Ash is a residue resulting from the burning of various organic substances. These can be: firewood, straw, dried tops of garden plants, conifer needles, coal and other materials.
Plants infected with various diseases cannot be sent to compost, but ash is allowed to be used after burning!
The properties, the chemical composition of the future mineral fertilizer will depend on the feedstock.
Ash is obtained from:
- Hardwoods and crops with thick stems (sunflower, buckwheat).
This ash contains a lot of calcium, potassium. These minerals will serve as a good fertilizer for garden crops and will ensure that the pH level will be restored to acidified soils.
This ash, in addition to a high content of calcium, is rich in phosphorus irreplaceable for plants.
Wood ash is considered to be one of the most valuable types of mineral fertilizers of natural origin.
Peat ash is not as common, it has almost no nutritional value for garden crops. And because this ash is less in demand among gardeners. Basically it is used as an impurity to maintain the optimum pH of the soil.
Ash based on it is not very suitable for fertilizer, because it contains a small amount of useful substances. It is used on alkaline soils for the purpose of their acidification.
Autumn biomaterial is conveniently stored and then burned in barrels. Leafy ash can be used both in the form of self-feeding, and as a mineral additive for compost.
Separately, it should be said about the ash remaining after smoking cigarettes. It is used as a fertilizer for indoor flowers. In addition, the ash perfectly protects home plants from small midges and fungal diseases.
Collect ash should be immediately after cooling. Soaked ash is not endowed with useful qualities. And because it should be protected from moisture.
Composition and properties
Ash is famous for its beneficial properties and rich mineral composition. Due to this, it is able to improve the qualitative composition and structure of the soil, saturate it with irreplaceable elements, improve air exchange, strengthen the immunity of plants.
The ash contains:
- calcium (in different compounds: carbonate / silicate / chloride / sulfate),
- potassium (in the form of orthophosphate),
- sodium (in the form of chloride),
- magnesium (in the compounds: silicate / carbonate / sulfate),
- Able to improve the structure of the soil - to make it more loose.
- Increases fruiting on heavy soils.
- It improves the air permeability of the soil, thanks to which the plants grow and develop better, and the simplest inhabitants are able to simply fully exist.
- It accelerates the decomposition of organic matter, because it is always added to the compost heaps as a separate layer.
- The ability to maintain a positive impact on the soil for 2-3 years.
Is it possible to use?
Wood ash in the role of mineral fertilizer can be applied on any type of soil. In this case, the pH of a little or strongly acidified soil will try to correct. Neutral soil ashes enrich the full range of mineral elements.
It is used to fertilize houseplants and a large number of garden crops: zucchini, tomatoes, potatoes, pumpkins, eggplants, and many others.
Ashes are introduced mainly in autumn when preparing the land for winter.
Do not use ash for fertilizer:
- Berries loving acidified soil: lingonberries, blueberries, cranberries.
When ash is introduced, the soil becomes neutral, and therefore these berries simply stop growing.
These crops react to ash by rapidly releasing arrows, as well as by stopping the growth of root crops.
- Flowers: camellia / rhododendron / azalea.
They immediately stop blooming and stop growing.
These plants grow well only on acidified soils.
Before applying the ash must be adapted. It is usually used in three ways:
- By placer on the beds, between the rows, holes, under shrubs and trees.
- Through watering or spraying (pre-prepared infusion based on the ash).
- As a component for compost. The optimal dose is 2.5 kg per cubic meter.
Gardeners mainly use straw, hardwood and wood ash. Strengthen the degree of its effectiveness will help mixing with other organic fertilizers. Together with humus or peat, ash is a powerful mineralizer. The average mixing ratio is 1: 3. This fertilizer can be immediately used, evenly distributing the plot. Plants will not be difficult to assimilate all the nutrients from such a complex.
It is also good in composts. Moreover, no full-fledged compost is possible without its introduction. Ash has the ability to accelerate the decomposition of organic matter. So, peat compost will require 45 kg of wood ash per ton of basic raw material. It perfectly neutralizes peat acidity.
Ash is not desirable for mixing with fresh manure, chicken manure due to possible loss of nitrogen. And its combination with superphosphate will reduce the access of horticultural crops to phosphorus. For a similar reason, do not mix ash with lime.
Rules for making clean ash:
- Prepare small grooves (approximately 15 cm deep).
- Ash is poured into them. One adult plant consumes about 2 kg of this mineral supplement per season.
- An ash-based water solution is prepared (at least 2 glasses are needed for the bucket), which is then shed in the ground.
- The grooves are buried.
For the garden
When planting spring seedlings of vegetables, wood ash is used directly in the wells (9 g per furrow), not forgetting to mix it with the soil.
Bean crops and greens are very responsive to ash: they are able to assimilate up to 200 grams per square meter per season. m
Squashes and pumpkins are fed with ashes at least 3 times per season: during the spring preparation of the beds, before planting, approximately in the middle of the growing season along with watering. Each time used 200 g per square. m
Peppers and eggplants are fertilized twice: when digging in the spring (600 g per meter), when planted (100 g per well).
Cabbage and turnips are fed with ash 2 times: during planting (a handful per well) and in the form of a solution for spraying during active growth.
Under the garlic in the fall make 400 g of substance per square meter. m
For carrots, celery, beets, one spring dressing will be enough - a glass of ash per meter.
Potatoes are fertilized with ashes 3 times: with spring digging (200 g per meter), directly into the wells when planting (3 large spoons each), with secondary hilling in the form of a solution (400 ml per bush).
For cucumbers, 2-3 additional feedings will be needed: spring - using the method of scattering ash in between rows (50 g per meter), while growing and the appearance of ovaries - when watering with the addition of dry matter (1/2 liter per bush).
Tomatoes require 4 supplements: 2 dry and 2 wet. The first time the ash is used when digging the ground under the beds (1/2 cup per meter), the second - when planting by spreading between plants. The next 2 wet dressings are carried out during the period of active growth and in the process of fruiting (up to 1 l per plant).
Responds well to the introduction of ash currants. Up to 600 g of dry matter is required for an adult shrub. In the process of growing season, you can shed the bush also with an aqueous solution of ash. Because of this, currants bear fruits better and become more resistant to diseases and some pests.
Strawberries are fed in 2 ways: root and foliar. The first do 2 times a year - before the rapid flowering, after the end of fruiting. Ashes are simply scattered between the rows (65 g per meter). Foliar fertilizing (spraying method) is carried out in the process of setting berries. Enough half a cup of dry matter in a bucket of water. Spraying produced at the rate of 1 l per square. m
Fruit trees are often fed with a liquid ash solution about once every 2-3 years. Enough 2 kg per bucket of water. This is a portion for one adult tree. For seedlings enough 1 kg. Ash helps to resist attacks of pests and gives the plants the necessary mineral feed.
Potted flowers periodically fertilize at the rate of 3 large spoons per 200 ml of water, garden ones twice a season. First, when preparing the beds in the spring (200 g per meter), then - a glass of dry mixture per well when disembarking.
Especially love ash roses. It stimulates the development of future inflorescences, protects against diseases, strengthens their immunity, making them more resistant to temperature shocks.
- Ash is good to use on clay soils and loams in the process of autumn digging. On sandy soil, it is better to transfer top dressing with ashes to spring.
- If the ash consumption is 300 g per meter, you can forget about the additional mineralization of the soil in the next couple of years.
- On acid soils, the ash is good in the autumn - it will help the plants to better endure the winter.
- Depriving the ash fertilizer compost is like leaving a chemical reaction without a powerful catalyst.
- It is good to use an aqueous solution of ash for soaking the seeds before sowing. Ash is a powerful growth promoter.
- It is better to store it in a closed container that does not allow moisture to pass through.
- At the same time with the nitrogen can not be ash. These two substances neutralize each other. You must wait at least about 30 days.
If possible, it is best to spread 2 of these substances in different seasons: nitrogen - in the spring, ash - in the autumn.
- If household waste or plastic gets into the barrel when the biomaterial is burned, the ash becomes useless due to its high toxicity.
- In fresh manure, the ashes are not appropriate - it will reduce the nitrogen content and will promote the formation of compounds that the plants simply cannot absorb afterwards.
- It is forbidden to fertilize saplings with ashes until the first leaves appear. At this point, nitrogen fertilization is more relevant - to stimulate growth.
- When fertilizing tomatoes or crops of the pumpkin family, the ashes are thoroughly mixed with the earth in order to avoid burns of their root system.
- If the acidity level of the soil is 7, the introduction of ash is unnecessary. Acidification and alkalization of the soil always leads to worse absorption of nutrients by plants.
Wood ash composition
Ash quality depends on many circumstances - the most important of which is the raw material - the type of wood burned in the fire.
The most valuable is ash produced by burning. birch wood. It contains in its composition of potassium 10-12%, phosphorus 4-6%, calcium 35-40%.
Ash formed by burning spruce wood contains potassium 3-4%, phosphorus 2-3%, calcium 23-26%.
But the most important thing in making ash is that plastic packaging, polyethylene, rubber should not get into the fire.
Potassium in ashes is contained in the form of potassium carbonate, easily soluble in water. There is little phosphorus in wood ash, but it is used more completely than from superphosphate.
A large amount of calcium in the ash makes it a good alkaline fertilizer that can quickly deoxidize the soil.
Ash application reduces acidity, improves soil structure and creates favorable conditions for the development of microflora.
When lime is deoxidized, it should be remembered that crops such as carrots, parsley, and radish do not tolerate lime well. In carrots, the root crop is bent, and in the rest it coarsens. Therefore, under these crops, the soil is best deoxidized wood ash.
Video - The value of wood ash for future harvest
Ash can be added directly to the wells when planting potatoes, seedlings of tomatoes, peppers and other vegetable crops, as well as in planting holes when planting fruit and berry crops.
Ash can be applied to almost all crops, with the exception of plants that love acidic soils. These include rhododendron, sorrel, azalea, hydrangea and others.
Do not apply ash with nitrogen fertilizers. - fresh manure, ammonium sulfate, ammonium nitrate, urea. This leads to nitrogen losses.
Do not mix ash with superphosphateThis contributes to the transfer of part of the phosphorus to an insoluble state, worsening the phosphorus nutrition of the plant.
Wood ash as fertilizer
The addition of ash to compost gives a positive effect - the decomposition of plant components is accelerated, the activity of microorganisms is activated.
It is possible to carry out top dressing of garden cultures during the whole season. If in the first half of summer the plants need more fertilizers with nitrogen content, then in the second half with potassium and phosphorus content - which is rich wood ash.
When feeding the ashes can be introduced in a dry form, then loosened to be buried in the soil.
Also prepare a solution of ash: To prepare a solution for 10 liters of water, add 100 grams of ash and mix well. Without waiting for the insoluble part to settle down, they water the plants - tomatoes and peppers, 0.5 liters each, under a bush. Feeding is carried out necessarily after watering.
Many gardeners used ash for soaking seeds before sowing. For 1 liter of water, add 2 tablespoons of ash, insist 2 days and then strain.
Disinfecting and healing properties of ash known to people from ancient times. Dry ash powders strawberries immediately after flowering, which greatly reduces the likelihood of infection. gray rot.
It is possible to powder with ashes and other cultures - cucumbers, tomatoes, berry bushes and fruit trees. This is done in the early morning, before the dew has come down or by pre-spraying the plant with water.
Pest control solutions are used which include ash - boil 100 grams of wood ash in 1 liter of water for 15 minutes, infuse for 2 days, strain. Add another 1 liter of water and 10 grams of soap.
Ash has almost no statute of limitations, but it should be stored in a dry place. When it gets wet, it loses almost all potassium.
Attention! Always follow the norms for applying any fertilizer to the soil; an oversupply of fertilizer is as harmful as a shortage.
An excess of potassium in the soil delays the entry of nitrogen into plants.
Useful properties of ash
Ashes of plants may vary significantly in composition.. For example, potato tops are very rich in trace elements such as potassium. When burning tops, only sixty percent of this trace elements is lost. Needles, a valuable supplier of phosphorus, lose only fifty percent of this element when burned. But regardless of the species, all the ash has in its composition: zinc, calcium, sulfur, sodium and iron.
Wood ash as a fertilizer can significantly change the composition of the soil: to make it from acidic alkaline, and from solid and dense loam - an excellent loose soil. Ashes are very much loved by plants such as strawberries, strawberries, potatoes and currants. Due to the fact that there is no chlorine in its composition, it fits perfectly to these garden crops. Gardeners are so accustomed to using ash, it is difficult to imagine planting strawberries, cucumbers and zucchini without this natural fertilizer.
Of all types of ashes coal ash is almost never used due to extremely low nutrient content and very dense texture. Its only use is drainage for indoor flowers and the oxidation of alkaline soil. Hardwood is the best ash.
As it was repeatedly noted, the ash deposited in the soil significantly increases plant resistance to diseases and insect pests. She sprinkled the ground in pots of indoor crops, when they get blackflies. This fertilizer also perfectly saves from fungal and bacterial diseases.
What does the ashes give to our garden?
- Significantly improves the quality of heavy loamy soils. With its help, such soils acquire the ability to be easily processed and become suitable for vegetable growing.
- Wood ash makes the soil friable, which contributes to the vital activity of beneficial microorganisms living in the ground.
- Ash is an affordable and free mineral fertilizer. After it has been applied, the soil remains well-fertilized for three years.
- If ash is applied along with organic fertilizers, the latter will decompose faster. Thus, their activity increases.
Ash has proven itself in pest control. With its help they treat black rot, powdery mildew, and also get rid of midges from houseplants.
To cure the plant from powdery mildew, make the following solution: combine a tablespoon of ash with a liter of soap solution, mix and spray the leaves and stems of the plants with this mixture. This should be done after the sun sets.
To rid strawberries of black rot, spray the ashes over the bush. Try to make it so that it covers all parts of the plant with a thin layer. Usually two procedures are enough to get rid of the disease.
Calcium carbonate in the composition of the ash contributes activating growth and building green mass. It enhances metabolic processes in plant cells and directly affects the rate of maturation. Its effect on tomatoes and other nightshade is especially noticeable. If they are fed room or garden flowers during the budding period, the inflorescences will grow large, with bright and rich shades of petals.
Если после посадки огурцов в почву внести удобрение с повышенным содержание карбоната кальция, то рост их значительно усилится, а качество плодов будет высоким.
Кальция силикат действует на пектиновые соединения, которые склеивают клетки. Если в почве будет ощущаться недостаток этого элемента, то луковицы высохнут и расслоятся. Therefore, for all bulbous it is very important to water the ash dissolved in water.
Salt in fertilizer is an important substance., providing cell fullness with moisture. It helps to keep fluid in fruits and other parts of plants, which is extremely necessary during a drought.
Magnesium is important for the formation of a sturdy stem. All cereals use it as a building material for building starch and carbohydrates in the composition of the grains. A lot of magnesium is required for flowers, such as roses, which will wither and shrink when there is a shortage of this element.
Potassium orthophosphate does not allow ammonia to accumulate in the leaf plates. With it, garden crops such as grapes, chrysanthemums and roses tolerate wintering well.
The use of ash in the garden
It can be diluted in water and used for irrigation, and it can also be applied dry. Share four uses of this fertilizer.
- When you prepare the beds in the fall, add ash to the soil and dig. So you prepare the soil for the spring planting of seedlings. You can also spray the ashes in the spring.
- Excellent proven watering plants with ashes. Such top dressing gained the greatest popularity in care of the potted plants and vegetables. For more effect, add peat in a 1: 2 ratio.
- Ash is applied directly to the beds during summer dressings. To do this, they pierce small grooves in close proximity to the stalks of the plants and pour them in a uniform layer. This method is not suitable for small shoots that have not yet gained green mass.
- The most popular way is to apply fertilizer when planting directly in the hole.
Wood ash has very little chlorine, which, on the one hand, is good for vegetable crops, and on the other, it is not. Indeed, thanks to calcium chloride, plants become more winter-hardy and less susceptible to diseases. It contributes to the storage of the harvest. So, carrots and strawberries are stored much longer, and tomatoes are not amenable to fungi during long-term transportation.
When ash is not good
Not all plants love this fertilizer.. For example, cranberries and blueberries prefer acidic soils, and ashes make this soil alkaline. This fertilizer can stop the development of flowers such as camellia and azalea. Ash radish is not suitable at all. It provokes the formation of seeds, while the root crop will remain in its infancy.
A very important trace element calcium sulphate is present in the ash in a small amount. It contributes to the growth of green mass and is extremely necessary for plants such as parsley, dill and sorrel. After the death of plants, this element remains in the soil.
It is impossible to feed the plant with ashes if white spots are found on it. The presence of speckled leaves indicates a glut of calcium.
In fertilizers, which are composed of synthetic phosphorus, do not recommend adding ash. This can badly affect the development of the root system.
There are some differences for different soil types.. So, if you fertilize loamy soil, then bring ashes during the autumn digging. If the ground consists of sandstone, then spring.
You can not combine it with fresh manure and weed tinctures. Dissolve them for a period. For example, first feed with ashes, and after ten days add manure.
The only soil in which ash is not applied is saline soils. For sandy and marshy ground it will be enough to take about one hundred grams of ash per square meter of soil. In order to neutralize the soil with high acidity, add burnt peat or shale. They need a lot: 500 grams per square meter of soil.
How to fertilize the soil
There are vegetables that just love wood ash.. Cucumbers and zucchini will be happy to feed. Water them with diluted ash once a month throughout the season.
- For onions that are planted in the autumn, they dig up a bed together with ashes.
- This fertilizer is also required for trees. Saplings up to three years old are watered with a solution of ash once a year, and in the future the dressing is reduced to once every two years.
- Mix the ashes with organic fertilizer and deposit in the pit for planting currants or raspberries. These shrubs will take root well and go into active growth.
- This fertilizer is perfectly combined with river sand. If you are planting seedlings of Bulgarian or hot peppers, mix ashes, peat and sand and add the mixture to the well.
The greatest amount of potassium can be obtained by burning vines of grapes, sunflower stalks and potato tops. The inferior ash of buckwheat, nettle and cereal straw is slightly lower. Phosphorus-rich will be ash from the leaves of all fruit trees. Calcium is very abundant in shale, peat and ordinary wood. Do not use burnt polymer materials, paper from glossy magazines and rubber.
This fertilizer is valued by the fact that potassium, phosphorus and calcium are in it in the most favorable form for learning. For example, phosphorus is absorbed much better than synthetic superphosphate, and a very small amount of chlorine in the composition of the ash makes it a universal fertilizer. Therefore, the ash can be safely used to feed potatoes, raspberries and grapes, that is, those plants that are very poorly tolerated chlorine.
Usually, the ash is simply diluted in a container and insisted throughout the day. For indoor plants and seedlings, it is dissolved in boiling water, and stirred throughout the day. In order to get rid of pests and fungi, the ash should be boiled over low heat, and for better effect, also mixed with soapy water in a 1: 1 ratio.
Observe precautions when handling ashes. Protect your eyes, mouth and nose from ash in the airways. Keep it in a dry place. Usually used for storage bag or hermetic dishes.
What fertilizers are wood ash?
Ash is the remnant of the complete combustion of organic matter, it is ash, which does not contain unburned parts. During combustion, all organic components are destroyed and inorganic mineral elements remain, their composition depends on which plants are burned.
Thus, wood ash is a mineral fertilizer, it contains a set of useful substances that are in the most accessible form for plants.
The remains of burnt organic matter containing a large amount of calcium, reduce the acidity of the soil, helping to neutralize its composition with an excess of acid.
The use of ashes for plants is also in the ability to scare away harmful insects and loosen the soil, that is, to improve the structure.
Ash is a phosphate-potash fertilizer, but only this does not exhaust its properties, since other elements of the composition are also necessary for plants. Their important feature is a good dissolution in water.
The content of nutrients in the ashes
The plants contain different substances, their quantitative characteristics also vary greatly, therefore the composition of the unburned residue is not the same.
The following table describes the average fertilizer parameters:
The main useful properties of the components:
- Calcium carbonate stimulates an increase in the green part, accelerates metabolic processes and vegetation. Provides growth and development of flowers, increases the pomp and beauty of the buds, and therefore is used, in particular, for roses. Stimulates the development of lash cucumbers, good fruiting. Used to increase the yield of solanaceous (tomato).
- Calcium sulfate - an indispensable element for the formation of a young plant, therefore, is used to stimulate the growth of seedlings. Included in the superphosphate.
- Calcium chloride accelerates enzyme formation in plants, accelerates photosynthesis. Strengthens resistance to frost, which is important for the northern areas when growing horticultural crops, for preserving grape vines, for strawberries.
- Magnesium strengthens the root system, stimulates photosynthesis, provides energy for growth.
- Sodium provides absorption and movement of moisture, maintains water balance.
- Potassium needed for growth, cell division, strengthens the protective forces of the plant, regulates the distribution of nutrients.
This composition of wood ash makes it possible to use it as a safe and complete fertilizer for the garden, garden. The most useful is the ash obtained by burning tree branches, straw of cereals.
When do you need to fertilize with ashes?
Top dressing with burnt organic allows to improve the harvest in the garden. Ash is also used as a fertilizer for indoor plants, which increases the growing season and flowering time.
Rules for making feeding for different soils:
- for light, sandy - 200 grams per square meter,
- on loam - up to 800 grams.
Excess dosage may result in alkaline imbalance. In general, the introduction of ash into the soil is used to reduce the acidity, it facilitates heavy marshy clay soil, saturates them not only with minerals, but also with oxygen due to loosening.
Fertilizer is applied in the spring before planting (root), in the winter before digging and during the growing season.
The greatest benefit brings ash to the following types of crops:
- cucumbers, zucchini,
- eggplant, pepper,
- onion garlic,
In general, fertilizer is applied in case of potassium deficiency. Yellowing and drying of the leaves testify to its lack. If the foliage on the plant begins to grow brown, curl, become covered with rust stains, you need to get the ash and begin feeding.
Ashes are useful not only for tomatoes and cucumbers, they can process flowers, shrubs, trees.
How to apply fertilizer?
To the maximum benefit from feeding, you need to choose the most appropriate option for the delivery of fertilizer.
Powder poured during planting. The main condition - do not pour directly on the roots. The required dose of top dressing is mixed with earth or sand and distributed in the fossa.
- grass seedlings - 1-3 tablespoons,
- bushes - glass,
- trees (seedlings) - a kilogram (1/5 of the bucket).
So feed the seedlings during the landing. Wood ash is also used as a fertilizer for potatoes, which significantly increases the yield. If the entire site is not digging, ashes can be added to the hole with a tuber when sowing. If the entire plot is dug, it is possible to feed in the course of work on the whole area, without laying each tuber separately.
The scattering of dry powder is performed during flowering and the formation of the ovary, while you can sprinkle the leaves and trunks to repel pests. During the pre-winter digging, ashes are brought to the entire area, trying not to leave dry fertilizer on the surface so that it will not be blown away by the wind.
Ash sandwich compost to enrich it with minerals and accelerate decomposition. A glass of powder sprinkled on 2-3 square meters, closing the next layer of compost.
Sprayed with infusion or a decoction of the ashes of the plant during the growing season. It is possible to process in this way not only the ground part of plants, but also seeds, tubers, and bulbs before planting.
Before using the ash solution in a spray bottle, thorough filtration is required. Spraying delivers beneficial substances to the leaves, the stems, saturating them with trace elements, and creates a barrier from pests.
It is necessary to make wood ashes during the active growing season, especially if the seeds were not processed before sowing. Ash solution is prepared by entering 1-1.5 tablespoons of powder per liter of water. After insisting during the day, you can water the seedlings.
What not to do?
Applying wood ash, you need to adhere to the following rules:
- Do not use with fresh manure, compost, bird droppings.
- Do not combine with mineral fertilizers - nitrogen and phosphate.
- Do not fertilize with ashes of earth with alkaline soil (up to 7 ph).
- Young shoots of seedlings watered after the appearance of the third leaf.
We should not forget that some plants (mountain ash, horseradish, sorrel) love sour soil and they do not need enhanced treatment with ashes.
Excess ash can adversely affect soil inhabitants - good bacteria, worms that loosen the soil and are needed by plants. It will take a long time to restore the composition of the soil.
You also need to remember that it is impossible to pour ashes on open roots, you need to connect it to the ground.
What is wood ash mixed with?
Use of top dressing is possible in several ways. We give the most common and proven:
- Solution. For seed treatment and increase germination apply a teaspoon of ash in a glass of water. Soaking lasts from 2 to 5 hours. If you want to fertilize garden crops, pour 1.5 cups of ash onto a bucket of water and mix thoroughly.
- Infusion. Many gardeners prefer to defend ashy solution for 1-2 days.
- The broth is prepared by boiling (30 minutes) in a liter of water 100 grams of ash. Before use, combine with water (10 liters). Used for vegetable crops (1.5 square meter bucket).
Here are the main ways to determine the weight of the ashes in the absence of scales:
Composition of wood ash
When the firewood burns, nitrogen and sulfur go into the air in the form of gases, and calcium, potassium, magnesium, various trace elements remain. Carbonates, oxides, remaining after burning wood, when introduced into the soil neutralize its acidity.
The value of fertilizer from burned trees depends on the type of wood you burn. As a rule, ash from deciduous trees contains a higher percentage of nutrients than ash from coniferous trees.
Anyway wood ash is an alkaline complex fertilizer. Its main advantage is a high content of calcium, potassium, magnesium, sodium, phosphorus in a form accessible to plants.
Burned wood does not contain nitrogen, which volatilizes when burned. However, this is not a reason to bring nitrogen fertilizers with it. The benefits in this case will not be, as this will lead to the formation and release of ammonia, large doses of which are dangerous to plants.
The introduction of ash helps to reduce the acidity of the soil. It is not recommended to deposit it on soils with acidity indicators (pH) of 7 or higher, since this will contribute to an even greater increase in the alkalinity of the soil. It is scattered under the digging of the soil or in the grooves, the wells during planting. The maximum consumption rate for soil digging should not exceed 1 cup per square meter. In this case, its action will be observed for 2 to 4 years after application.
Ash solution or infusion of wood ash - how to cook
It is possible to use the so-called ash solution or ash extract for fertilizing plants. It is prepared as follows: 1 cup of wood ash (100-150 g) is poured with a bucket of water, insist (I leave it overnight). Garden plants are watered with this solution. Before watering the infusion is stirred. Insoluble ash particles should be evenly distributed throughout the mixture.
Wood ash - use in the garden, where you can, and where you can not
Burned wood can be successfully used in compost heaps to help create the best conditions for microorganisms that process organic matter. Sprinkle ash on each layer of compost to enrich the latter with nutrients.
When used reasonably, it can be used to combat various pests, such as slugs or snails, as it draws water from invertebrate organs. Sprinkle ashes around your plants to scare away creeping pests. But as soon as the ashes become wet, it loses its deterrent properties. Its continuous use for these purposes can increase the soil pH much, and this is harmful for plants.
Wood ash does not contain chlorine, so it can be introduced under grapes, citrus fruits, strawberries, potatoes, raspberries, currants, as these crops do not tolerate chlorine. In addition, this fertilizer protects, for example, cabbage from diseases of the keel (a disease caused by a fungus parasitic on the roots) and black leg.
Wood ash should not be added around plants such as rhododendron, blueberries - they love acidic soil, but it reduces the acidity of the soil, which will depress these plants
Potato responds well to its use in cultivation - potato crispiness increases by 1-1.5%, but still use it carefully when planting potatoes, as it contributes to the development of such a dangerous disease of tubers, like rhizoctoniosis or scab.
Do not use wood ash to fertilize seedlings before the third true leaf appears, as it contains too many salts that are harmful to weak plants. When planting seedlings of tomatoes, peppers, eggplants, you can add 1 tablespoon of zolka to the hole, but be sure to mix it with the earth, and also sprinkle it on top of the soil so that the roots of the seedlings do not touch it, otherwise they will get burned - the plant will hurt, take a long time to settle in a new place.
Do not use wood ash to repel pests on radish, radish or turnips - you may scare away the pests, but the harvest of radishes and others like it will not wait - they will go "arrow", that is, the roots will stop growing, chop, stiffen - they will release flower the arrow.
Dry wood ash during storage does not lose its beneficial properties over the years. But when soaking, it loses almost all of the potassium. Процент калия в пепле зависит от породы и возраста сожженного дерева. Чем оно моложе, тем больше содержит калия.
По сравнению с калием фосфора пепел содержит мало, но такой фосфор используется растениями лучше, чем из суперфосфата.
Зола грецкого ореха как удобрение
Некоторые дачники опасаются вносить в почву золу древесины грецкого ореха. Their fears are most likely based on the fallacy that the plants of the nut family (walnut, manchurian, gray and black) contain the chemical juglon (nuqing) belonging to the naphthoquinone class. This substance has an adverse effect on plants growing close to the nut.
Their fears are unfounded. In the walnut plant, the juglon is in green peel, leaves, roots, and also the bark. When fully burned, juglone, as an organic substance consisting of carbon, hydrogen, oxygen, completely decomposes and disappears. Ash from walnut wood, as well as from other woody crops, contains potassium (15-20%), calcium (6-9%), phosphorus (5%), in small amounts magnesium, iron, sulfur, zinc. In addition, it includes many other trace elements needed by vegetable crops.
Walnut shell ash can be used as a cosmetic tool, for example, to remove unwanted hair. The following recipe is recommended: shells of nuts are burned, the ashes are diluted with water. On one teaspoon of gold take 0.5 liters of water. The resulting composition is used to lubricate the skin with unwanted hair.
What other ash can be used as fertilizer
In the garden can be used as a fertilizer ash from burning husks of sunflower, rice husk.
When sunflower husk is burned, it is formed in the amount of 0.5-1.0% of the total volume. It is very rich in potassium, can be used as a valuable potash fertilizer. Sunflower husk ash, as well as buckwheat straw, are leaders in potassium dioxide (K2O) Compared to woody or from other plants. You should know that when burning sunflower husk, nitrogen from it evaporates into the atmosphere. Therefore, the ash, unlike the husk itself, does not enrich the soil with nitrogen, as well as woody.
In addition to sunflower husk, in areas of the Krasnodar region, where rice is cultivated, a considerable amount of rice husk is obtained.

Dry feeding from ash
Ash is often poured into planting pits as dry fertilizer. The application rate may vary depending on the crop, but on average a small handful of powder goes into one well (3/4 tablespoon per 1 square meter of soil).
Please note that in the fall, during the rainy season, it makes little sense to add ash to light sandy soil - it is easily washed out.
Ash fertilizer for lawn
Ash has a beneficial effect on the beauty and freshness of the grass carpet, and in addition also absorbs harmful substances on the soil surface, preventing them from “poisoning” lawn plants.
So, how to cook the ashes for feeding the lawn? The secret is that you do not need to cook it at all! It is enough to spray it over the lawn in the fall or early spring, immediately after the snow melts.
For these purposes, you can use not only coarse ash, but also crushed charcoal.
2. Ash - a great alternative to lime
Speaking of improving the quality of the soil. Sprinkle it with ashes is a good alternative to chalking. As well as lime, ash "quenches" the excessive acidity of the soil, neutralizing its pH.
For these purposes, the ash obtained after burning peat is ideal.
Naturally, ash will not bring any benefit to crops that love acidified soil (conifers, hydrangeas, rhododendrons, heathers, blueberries, etc.). On the other hand, this feature can be used to control weeds: alkali is not to the taste of horsetail, wheat grass, woodlouse, malicious enemies of beautiful lawns.
3. Ash against pests and diseases

For example, prepare soap and ash solution: 3 kg of fine sifted ash pour 10 liters of hot water, insist under the lid for two days.
After this infusion filter. In 500 ml of hot water dissolve 40 g of tar or household soap, pour it all into the infusion of ash. The resulting solution can be sprayed plants several times per season with an interval of 1.5-2 weeks during the season.
You can also modify this recipe by adding instead of the infusion of ash a water extract of ash prepared according to the above recipe (500 ml) and 10 liters of herb decoction (tansy, tomato tops, yarrow).
5. Ash as a substitute for tablets.
Did you know that ash can be useful not only for the health of the garden, but also for the health of its owner?
