Potassium nitrate (potassium nitrate): properties, how to apply to feeding


Potassium nitrate is used in agriculture on a large scale. This fertilizer is used in agriculture on an industrial level and gives good results. Most often, fertilizing is used for additional nutrition of plants that do not organically tolerate chlorine. In the private sector, potash (potash) nitrate is usually applied as a fertilizer for strawberries, raspberries, beets, carrots, and grapes.

Properties of potassium nitrate and its benefits for plants

The formula for potassium nitrate is KNO3. Nitrate is called any salt with a nitrogenous residue - it is an acidic residue NO 3, obtained from nitric acid, it is called nitrate. Since, in addition to such a residue, there is potassium K, saltpeter is called potassium. Other names for the substance are potassium nitrate or Indian nitrate.

The main elements of the fertilizer are nitrate and nitrogen, as can be seen from its formula. These substances are very useful for plants: nitrogen accelerates the growth of crops, potassium improves the ability of roots to absorb nutrients from the soil. Another plus of potassium nitrate - with its use of breath plant cells are improving, because the agent catalyzes biochemical reactions in the cell. As a result, the plant's immunity is activated and, as a result, the resistance to many diseases increases, as well as yields increase.

As already mentioned, in potassium nitrate the main effect on plants turns out to be two components. Compared to other fertilizers, the percentage of potassium in this substance is higher than the percentage of nitrogen (44% vs. 13%). This makes it possible to produce additional feeding even after flowering of plants and the appearance of ovaries. Such a percentage of nitrogen will make the plant stronger, but will not contribute to the excessive growth of greenery and therefore will not prevent the plant from "throwing strength" on the formation of fruits. The use of potassium in the composition of nitrate will contribute to the good development of the fruit and their high taste.

Potassium nitrate is usually sold in the form of small white crystals. Sometimes it has the appearance of a white powder, but when storing this form of fertilizer, you should be careful and keep it tightly closed to avoid caking. Potassium nitrate is highly soluble in water, so it is easy to prepare top-dressings for agricultural plants in liquid form.

The use of potassium nitrate for fertilizing

KNO3 is used for both root and foliar dressings. Best used means for root crops, such as carrots and beets, as well as for fruit trees and berries (including tomatoes). It is better not to use saltpeter for potatoes, since it “likes” phosphorus, there will not be much effect from the addition. The same applies to radish, cabbage, greens.

After fertilizing with potassium nitrate greatly increases the yield of plants, the size of the fruit. As a result of the formation of fruit sugars, the fruit pulp becomes tastier. If you make a means at the time of laying the ovary, then after fruiting you will receive more than the deadly fruit that will be stored longer than usual.

Root top dressing

Despite the fact that KNO 3 can be used both in dry and in liquid form for top dressing, the solution is often used because of its speed. The following recipes for root dressings proved to be well (add liquid under the root, into the hole, near the stem):

  • 15 grams per 10 liters of water - for garden flowers
  • 20 grams per 10 liters of water - for berries
  • 25 grams per 10 liters - for fruit trees

This type of fertilizing is carried out 2-3 times a month..

Foliar feedings

Extra root dressings (for spraying plants) are made with a concentrated solution, since the liquid evaporates from the leaves. To prepare such a solution, take 25 grams of fertilizer. 10 liters of water. Spraying produced from the following consumption:

  • 0.7 liters per 1 square meter - strawberries, flowers, garden ornamental plants
  • 1 liter per 1 square meter - shrub berries
  • 1.5-7 liters per 1 square meter - fruit-bearing trees (here the volume is calculated based on the age and size of the tree)

In one summer, produce from two (minimum) to four (maximum) foliar dressings. The last time sprayed the plant no more than a month before harvest.

If the crop has ripened earlier than it was calculated, then the procedure is as follows: to wash the fertilizer off the fruit, a tree or berry bushes should be watered with a strong stream of water (preferably from a hose) with a spray nozzle. The first time is such a watering 10 days before the removal of fruits and berries, it must be repeated three times a day. Last time - a couple of days before picking the fruit. Water should be poured over the plants very carefully so as not to knock down the berries and fruits.

Application in other areas

In addition to use in agriculture, There are other uses for potassium nitrate:

  • used in the preparation of black powder and other substances for the production of pyrotechnics,
  • in industry (optics, glassmaking) it is used to discolor and brighten technical glasses, as well as to give strength to glass products,
  • molten potassium nitrate is used to produce a simple potassium substance,
  • used for the processing of nickel ores in metallurgy,
  • in the industrial manufacture of products KNO 3 is used as a preservative E252, when used for meat products, they produce potassium nitrite, which has an antibacterial effect

Preparation of potassium nitrate

You can make potassium nitrate yourself if you have potassium chloride and ammonium nitrate.

For this, crystals of potassium chloride in the proportion of 1 part of powder to 2 parts of water. If the solution remains undissolved precipitate, you should strain it. To dissolve ammonium nitrate in the same proportion.

To merge both solutions in one dish and to warm in a water bath, until needle-like crystals appear in the solution. It is advisable to make these manipulations by airing the room. Dishes must be completely clean. If something gets into the solution, especially soda or sugar, an explosion is possible.

Cool the resulting solution to room temperature. Using the funnel and cotton fabric, it is possible to decant the residue of the solution and thus separate the crystals. They can be dried by putting on clean paper.

Composition and properties

Potash nitrate, as mentioned above, contains two main components that have a nourishing effect on plants. Moreover, unlike most mineral fertilizers, here the specific proportion of potassium (44%) significantly exceeds the specific proportion of nitrogen (13%). This ratio allows the use of potassium nitrate even after the plant has faded, and formed the ovary. A relatively small amount of nitrogen will strengthen the plant, but will not spur the growth of green mass, and will not “distract” it from the main task - the formation of fruits and berries. BUT Potassium, introduced at this stage, will lay the foundation for the qualitative development of the future harvest, and help fruits and berries to acquire excellent taste.

Small, fragile white crystals - in this form, most often you can buy potassium nitrate. Less commonly, it is sold as a white powder, which tends to clot, so bags with this fertilizer should always be sealed. This agro-rubber has a high hygroscopicity, which makes it easy to dissolve potassium nitrate in water, preparing solutions for feeding garden and garden plants.

What is potassium nitrate?

Potassium nitrate (also known as potassium nitrate, potassium nitrate, potassium salt of nitric acid) is a two-component fertilizer having the chemical formula KNO3.

It includes:

The active ingredients allow the use of this additive in almost any type of soil and throughout the growing season.

What features has potassium nitrate?

The additive is characterized by such properties:

Potassium nitrate, or potassium nitrate is a mineral fertilizer that is widely used in agriculture.

  • It has the appearance of white, sometimes yellowish, odorless crystals resembling powder,
  • sold in packages with a capacity of 1 to 50 kg,
  • it is well dissolved in water, hydrazine, glycerin, liquid ammonia (but not ether or ethanol) is suitable for the same purpose,
  • melts at very high temperature
  • flammable during heating, causing a danger
  • the composition is not volatile,
  • free from harmful additives
  • does not affect soil acidity,
  • effective for soils poor in potassium, and plantations that do not tolerate chlorine (potatoes, grapes, tobacco),
  • it is used on the open and closed soil: in the garden, flower bed, when feeding indoor plants,
  • it is well combined with other water-soluble fertilizing agents,
  • Tracked in case of prolonged storage in non-sealed packaging.

Why use this tool and how does it work?

Potassium nitrate is used to influence vegetation in the following directions:

  • improves the absorption of substances by the root system, increases its branching,
  • balances photosynthesis,
  • accelerates growth
  • improves the quality of tissue structure,
Most often, it is introduced as an additional food for plants that absolutely do not tolerate chlorine.
  • increases stress resistance, frost resistance and immunity,
  • increases yield (number and size of fruits),
  • prevents cracking of fruits, increases their safety,
  • improves the taste of fruit and berry products, contributing to the accumulation of sugar (beets, grapes),
  • prevents the development of bacteria and fungi.

For which crops is potassium nitrate used most often?

The most effective fertilizer by this tool the following varieties of vegetation:

  • root vegetables (beets, carrots),
  • berry plants (tomatoes, currants, strawberries, raspberries, blackberries, blueberries, grapes, gooseberries),
  • fruit trees.

A smaller effect is observed when feeding potatoes, cabbage, radish, greens.

What are the most productive ways to feed this tool?

Practicing the introduction of dry matter, but the fastest effect is observed when using exactly 2% aqueous solution.

Potassium from the composition of this fertilizer is much more useful to fruit trees and berries, including tomatoes.

There are two common ways to use a solution of potassium nitrate:

  1. Root top dressing. It is carried out once in 14 days, adding a working solution to the plant near the rhizome.
  2. Foliar feed is spraying with a sprayer. It is carried out from 2 to 4 times during the whole growing season. Requires a higher concentration of the substance in the solution (about 2.5 g / l), since part of it evaporates from the foliage and is washed off during subsequent watering. Consumption means:
  • for vegetables, flower and decorative plantings - 0.7-1 l / sq.m,
  • for berries - 1 l / sq.m,
  • for fruit trees - 1.5-7 l / sq.m (depending on the age and density of the wood crown).

After each application, plenty of water vegetation.

ATTENTION! Do not mix potassium salt crystals of nitric acid with an organic type of fertilizer (compost, peat, straw, sawdust, manure).

Best time to use

It is recommended to use the additive in certain periods:

  1. For the first time you need to make a substance in April.
  2. The second time - during the sowing of the soil (May).
  3. Provide the earth with nitrogen from the beginning of the formation of buds until the fruit ripens.
  4. In the summer, feed the vegetation in a foliar fashion, trying not to overdo it with the amount of the introduced substance. To stop this feeding should be a month before harvest.
  5. Autumn fertilizer of fruit trees will increase their frost resistance.
After adding potassium nitrate, the quality and quantity of the crop improves significantly.

Potassium nitrate - instructions for use for garden crops

Farmers and gardeners advise applying potassium nitrate to specific vegetable crops:

  1. Cucumbers. Fertilized solution in the phase of fruiting. Yields, but not growth of greens (stalks and leaves) increase.
  2. Tomatoes They are shown watering the seedlings, when 4 developed leaflets appear in it. Also, reprocessing of potassium nitrate is necessary a week before planting seed into the soil and picking up bushes.

Root introduction of the drug in the flowering phase of tomatoes will allow a 40% increase in yield.

  1. Roots. Potatoes, carrots, radishes and other crops are supplied with components of potash nitrate by introducing dry product crystals directly into the ground (up to 50 g / m2) during spring digging. Planting of root crops is carried out after a few days. Consider:
  • potatoes are processed during hilling, at the peak of the development of potato tops. It is recommended to mix this additive with phosphorus for the best effect,
  • cabbage and radish strengthened with potassium nitrate, mixed with calcium,
  • beets and carrots prefer a means without impurities.
As a fertilizer, potash saltpeter can be applied under plants in both dry and liquid form.

Dosage and methods of use of potassium nitrate for fruit trees, shrubs

Under the root, near the trunk or in the hole, make a solution in the dosage:

  • for berry plants - 1 g / l,
  • for fruit trees - 2.5 g / l.

For spraying consumption rates others:

  • berry bushes - 1-2 g / l,
  • fruit trees - 2.5-3 g / l.

Flowers and other decorative cultures of open areas

Floral and ornamental plantings of flowerbeds, garden plots also need additional nutrients, including potassium nitrate.

It is added in the amount of:

  • with root dressing - 1.5 g / l,
  • when spraying - 2.5 g / l (consumption - 0.7 l / sq. m).

It is used no more than 2 times a season, as a rule, on the eve of planting flowers on a flower bed (introduction of a dry preparation when digging up the ground). Thus, the soil is enriched with minerals. Subsurface fertilizer solution is carried out a few days before flowering.

Saltpeter targets some varieties that react poorly with other types of fertilizer.

First of all, potassium nitrate is shown in colors:

  • small-bulb,
  • rhododendron
  • dahlias, tulips, gladioli,
  • lilies
  • clematis

Rules for the use of potassium nitrate for indoor plants

According to experts and consumer reviews, the dosage prescribed by flowerbed plants, in the case of indoor plants, should be reduced by half. That is, use the working solution in a concentration of 0.5 g / l.

Fertilizer is especially useful for:

  • violets
  • begonias,
  • orchids,
  • ferns and other exotic plants of subtropical origin.

Deciduous deciduous plants prefer watering with a complex solution twice a month. For its preparation you will need:

  • water (1 l),
  • potassium nitrate (0.1 g),
  • ammonium nitrate (0.4 g),
  • simple superphosphate (0.5 g).

The working solution can not be stored, after preparation it should be used immediately.

When greenhouse cultivation of vegetables and houseplants used saltpeter to strengthen plants

Precautions and storage of the drug

When choosing KNO3 for planting, remember that potassium nitrate is a dangerous substance:

  • is an oxidizing agent that reacts quickly with various flammable substances,
  • toxic
  • high concentration of the solution can cause irritation and chemical burns in humans.

The substance must be stored in a sealed package, separately from other fertilizers and household chemicals, as well as away from combustible substances and heaters. The package with bait must be protected from direct sunlight.

Safety during use:

  1. Do not inhale the substance, do not taste it, and do not apply the solution to the skin.
  2. Wear gloves, closed clothing and shoes when working with the working solution and dry granules. When foliar feeding (spraying) protect the respiratory tract respirator, and eyes - with special glasses.
  3. Do not use kitchen utensils when working with nitre.
  4. When the substance is heated, a fire or explosion is very likely, so do not use it in hot weather. For the same reason, do not mix the product with substances of organic origin. Do not smoke or make fire near it.

First aid:

  • If a substance comes in contact with the skin, wash it with cold water.
  • in case of contact with eyes, it is also recommended to wash them (during which the eyelids should be kept open),
  • after receiving a burn, apply a sterile bandage to the affected area and consult a doctor.

Compatibility of potassium nitrate with other drugs

This nutritional supplement is mixed with the following plant fertilizers:

  • lime fertilizers
  • potassium chloride,
  • phosphate rock,
  • potassium sulfate
  • urea,
  • ammonium nitrate.

Properly applying potassium nitrate, you get a high yield of excellent quality in the garden, increase the immunity and productivity of fruit garden crops, contribute to the development of flowers and other ornamental crops living in flowerbeds and indoors.

1 Properties of nitrate

Potassium nitrate - the most common the name of the substance with the chemical formula KNO3. According to the generally accepted nomenclature in chemical science, this compound is called potassium nitrate, potassium nitrate. In everyday life can be found the names of Indian or potassium nitrate.

Needle crystals are colorless, but when passing through a chopper, they may look white with a grayish tint. The substance is highly soluble in water and provides the plants with the necessary nitrogen and potassium for growth.

Potassium and sodium nitrate, though similar in appearance, are very different in hygroscopicity. Potassium nitrate is not inclined to lump up, but if this happens, you can dry the fertilizer on the battery for grinding and break up large pieces by mechanical means.

1.1 What is it used for?

Gardeners know potassium nitrate as an excellent fertilizer for all types of crops. The two-component additive allows not to contribute separately potassium and nitrogen supplements, especially since they block the absorption of each other.

The use of potassium nitrate is advisable when the excess nitrogen in the soil is avoided, as well as to feed crops that do not respond well to chlorine fertilizers (potatoes, currants, grapes, tomatoes).

Potassium nitrate performs at least eight functions:

  • helps root development, increases root branching,
  • accelerates growth, activates photosynthesis,

Preparation of soil for plants with potassium nitrate

1.2 How and when to contribute?

Potassium nitrate is convenient in that it can be applied either under the roots of a plant or sprayed with a sprayer. Fertilizing begin in the spring and continue during the growing season. In areas with potatoes and cabbage, potash fertilizers are usually applied during hilling, when the tops have reached the peak of development.

Useful potash support plants after the onset of budding and before the fruit ripens. At this stage, the minimum intake of nitrogen into the soil is desirable. Potassium nitrate meets this requirement: 13% of nitrogen accounts for over 40% of potassium.

Root top dressing is advisable to carry out 2-3 times per month, foliar - 2-4 times during the growing season.

Top dressing of tulips of potassium nitrate

The dosage of fertilizer depends on the type of crop:

  • for flowers - 1.5 g per liter of water,
  • for tomatoes and other vegetable crops - 1 g per liter of water,
  • for raspberries, strawberries, strawberries, gooseberries, currants - 1-2 g per liter,
  • for ornamental shrubs - 1 g per liter,
  • for fruit trees - 2.5 g per liter.

Top-dressing with a 2% potassium nitrate solution involves the use of a sprayer. It is more convenient to measure fertilizers, starting from the number of liters per square meter.

For berry bushes, this ratio is the easiest to remember - a liter per square meter. For flowers, vegetables, strawberries, 0.7 liters per square meter is enough. m. In the garden, you can navigate based on the age of trees: young seedlings of two liters, adults - up to 8 liters per plant.

2 How to make potassium nitrate yourself?

In the Middle Ages, the receipt of potassium nitrate suggested the presence of nitre. Organic waste - manure, straw, ash - were collected in a pile, where they were rotting. Nitrogen-rich organic matter, oxidized and recycled by nitrifying bacteria, turned into nitrate. This process was unhurried: the "maturation" of nitreid occurred two or three years.

More simple production of potassium nitrate was invented in the middle of the XIX century. This technology today can be used to prepare the substance at home. Equal parts of calcium chloride and ammonium nitrate will be needed. The process itself is a simple exchange reaction. No special device, no apparatuses are needed for the work - there is enough glassware that can be found in any kitchen (three-liter jars, bottles).

Homemade Potassium Nitrate Crystals

Instructions on how to make potassium nitrate at home are absolutely not difficult:

  1. Dissolve crystalline potassium chloride in hot water. One part of the powder will need two parts of water. Mix well, wait for the crystals to dissolve. If undissolved particles remain in the fluid, strain through cotton fabric.
  2. Ammonium nitrate is dissolved in the same proportion. - for one part of ammonium nitrate two parts of water.
  3. Drain the two solutions in one container (jar), put it in a water bath. Wait until the needles appear. The mixing process is best done in a well-ventilated area, with a hood.
  4. Cool the solution at room temperature. For the final cooling jar can be placed in the refrigerator.
  5. Separate the potassium nitrate from the remaining solution can be using a funnel and a fabric filter.
  6. It remains to dry the crystals. This can be done on clean paper.
  7. To obtain a product of high purity, you can recrystallize: once again dissolve the crystals in clean (distilled) hot water, filter the liquid product, cool, the precipitated crystals re-dry.

For safety reasons, use only clean utensils. Especially dangerous if the solution gets residual soda or sugar. A three-component mixture - saltpeter, soda, sugar - is the easiest recipe to create pyrotechnic effects. Therefore, if the desired product has nothing to do with smoke bombs, caution should be exercised.

Potassium nitrate is easy to store and easy to dose. Being well dissolved, saltpeter can be used as a root top dressing on the open ground, it is easily applied to the leaves using a spray bottle. If necessary, potassium nitrate can be made independently.

Properties and composition of fertilizer

Potassium nitrate is a very popular fertilizer for plants growing in any soil. She is improves the condition of plants and increases their protection in front of external factors. Nitrate increases nutrient absorption by the roots, stabilizes photosynthesis and plant respiration. Thanks to this feeding culture is much less likely to encounter diseases. It consists of only two active components:

It is a pure white crystalline powder. If it is stored for too long, it can be compressed, but its chemical properties do not suffer. One way or another, it is recommended to store potassium nitrate in a packed package.

Application features

On the garden plots and gardens carry out foliar and root fertilizer saltpeter. There is almost no chlorine in this product, so they can even process potatoes, tobacco and grapes. Excellent perceive this feeding tomats, beets, carrots, blackberries, raspberries, currants, decorative and flower cultures.

Experienced gardeners, who understand what potassium nitrate is for, do not recommend that she feed on cabbage, radish and greens. These plants do not perceive it very well.

To use such a feed is very simple. Potassium nitrate is on sale in small packages for summer cottage and garden, and for agricultural land it is packed in bulk bags.

Precautionary measures

Before using potassium nitrate you need to take care of safety measures. It is necessary to work with this substance in protective gloves made of rubberized material. It is also advisable to protect your eyes with glasses. It is advisable to wear tight clothing and a respirator before the treatment procedure, as a pair of top dressing can harm health.

If the substance accidentally gets on the surface of the skin, then it should be washed off as soon as possible with water and the affected place be treated with an antiseptic preparation. Potassium nitrate is oxidant that enters chemical reaction with highly flammable substancestherefore, this fertilizer should be stored as far as possible from such compounds.

. In the room where potassium nitrate is located, it is forbidden to smoke. You should also protect the access of young children and pets to feeding.

When using fertilizer it is necessary to provide protection to plants. To the drug is effectively absorbed, it is recommended to make its introduction when watering. Do not be too zealous with nitrate on acidic soils., because this feeding will oxidize them even more. To prevent crop burns, fertilizer should be applied as carefully as possible, making sure that it does not fall on the stems and leaves.

Cooking your own hands

To make potassium nitrate with your own hands, you must first prepare for the procedure and get all the necessary substances.

Buy potassium chloride and ammonium nitrate can be in any specialty store, and they are very cheap.

The mixture is made according to the following scheme:

  1. 100 g of potassium chloride should be thoroughly mixed in 350-400 ml of warm and clean water. Stir the mixture to complete dissolution of the active substance. After that, the composition must be thoroughly filtered.
  2. The filtered solution should be placed in an enamel vessel and put it on fire. After boiling, 95 g of ammonium nitrate must be carefully poured into the container. It is necessary to boil the product for 3-4 minutes, stirring constantly. Then it must be removed from the gas.
  3. A warm mixture must be placed in a plastic bottle and wait for it to cool. After the solution has cooled, it must be placed in a refrigerator for 1-1.5 hours. Then the composition must be held for 3 hours in the freezer.
  4. After cooling procedures, the water from the bottle should be carefully drained. At the bottom of the tank will remain ready for use substance. Her crystals need to be dried in a warm and dry room on a paper sheet for 3-4 days.

Composition, properties and features

Potassium nitrate or potassium nitrate, as it is also called, is a universal fertilizer used for almost any crop and on absolutely any soil. It is non-toxic and is a white crystalline salt (sometimes with a yellow tinge). Sometimes manufacturers produce this fertilizer in the form of crushed crystals, that is, in powder form. Potassium nitrate is a non-volatile, odorless substance that dissolves well in water, is well dissolved in glycerol or ammonia.

Tip During long-term storage, fertilizer tends to clot, but the chemical properties of the substance do not suffer from this. By the way, this process can be prevented by hermetically closing the package with the substance after each use.

Potassium-nitrogen mixture, which presents potassium (potassium) nitrate, is fundamentally different from other nutrient feedings used in agriculture that contains much more potassium than nitrogen (ratio of approximately 3: 1). Thanks to this feature, it is possible to use this nutrient mixture not only for plants that have begun their growing season, but also for ovaries that have formed.

Potassium nitrate is distinguished by unique properties that make it possible to have an incredibly beneficial effect on plants. So, for example, using this nutrient in the right ratio, you can help a plant:

  • accelerate growth
  • increase the strength of the root system
  • increase the respiration of plant cells,
  • activate the immunity of the plant, which will further help to get the maximum yield for a certain variety, because the plants will not be exposed to any pests and diseases,
  • to grow fruits of the greatest possible size and excellent taste,
  • improve their winter hardiness for fruit (perennial) and berry crops.

Application in gardening and horticulture

Potassium nitrate is actively used as a top dressing for most cultivated plants. Since this substance does not contain chlorine, it can be safely used to feed plants that are afraid of chlorine: potatoes, grapes, berries, carrots, beets, tomatoes, currants, fruit trees.

Tip From the use of this fertilizer should refrain from growing radish, cabbage and various greens. By the way, experienced gardeners note that potatoes are not the kind of culture that would be very happy with potassium (it is better to use phosphorus to feed them).

In general, potassium nitrate is considered a truly magical feed for cucumbers and tomatoes. And you can use it throughout the season. For feeding these garden crops most often used substance in liquid form. You can either prepare the solution yourself, or purchase it in finished form.

Tomatoes and cucumbers potassium nitrate helps to strengthen the root system, increase crop yield and speed up the processes of photosynthesis.

For feeding cucumbers used a solution of potassium nitrate, prepared using about 25 g of the substance in 15 liters of water. For dressing tomato bushes the substance is used in the same proportion, but it is introduced as a root dressing.

Potassium nitrate should be used only in combination with water: in no case do not mix it with organic fertilizers (peat, manure, etc.), as well as sawdust and straw.

During the entire growing season, plants should not be used too often: it is enough to feed the crops only 2-3 times. Otherwise, nitrates will accumulate in them. If you plan to feed root vegetables, you need to use only dry potash saltpeter. The crystals should be applied to the soil on the eve of planting crops in the following proportion: about 50 g per square meter.

Well, and finally, a few words about how to properly use potassium nitrate. Since it is an oxidizing agent, in no case do not mix it with combustible materials, as this may be a fire hazard. Keep the substance in hermetically sealed packaging, and work with fertilizer in rubber gloves and a respirator (foliar feeding).

This concludes the introduction of a valuable nutrient for plant nutrition in the garden plot. Good luck!

Features of potassium nitrate

So what is potassium nitrate and how does this feeding affect the growth of plants? Potassium nitrate or potassium nitrate is an inorganic compound, presented in the form of a white powder, which has no odor and is very well soluble in water. This substance no danger to animals, since it is absolutely not toxic.

Due to certain properties, potassium nitrate is widely used by many farmers and gardeners. It turns out that potassium nitrate, acting in plant tissue, performs a number of important functions due to which the vital activity of plants is significantly improved.

Positive properties

So potassium nitrate has following positive properties:

  • normalizes photosynthesis of plants,
  • provides garden crops with high resistance to various diseases,
  • through the use of potassium nitrate, the growth of crops is accelerated,
  • normal respiration of plant cells,
  • improves fruit set,
  • increases immunity
  • increased resistance to cold and drought.

It should be noted that the composition of potassium nitrate includes:

  • potassium, which accounts for about 40%,
  • nitrogen in the amount of 13%.

It is these substances that promote the good development and growth of many plants. However, it is necessary to take into account that if the soil contains an abundant amount of nitrogen, this may not lead to quite good consequences. The development of shoots and leaves occurs in an accelerated mode, and this phenomenon has a bad effect on flowering. Therefore, the best option nitrogen fertilizer application - the growing season. But the use of potassium will be appropriate during the flowering of the plant, its budding and fruiting.

Potassium nitrate belongs to the category of mineral fertilizers that perfectly absorb moisture from the air. Therefore, so that the potassium top dressing does not turn into lumps, it is hermetically packed. Of course, this phenomenon does not affect the properties of potassium nitrate, but the use of this fertilizer in this state causes some discomfort than using it in a crumbly form. Therefore, it is recommended to pack it well after using a potash fertilizer in order to avoid such consequences.

One of the negative and even hazardous properties of potassium nitrate is that this substance can easily ignite. To avoid any dangerous situations, it is necessary to store potassium nitrate in a cool dry place away from direct sunlight. Moreover, there should be no substances near with which the potash fertilizer could react.

To which plants can potassium nitrate be used?

An additional advantage of using potassium nitrate is that chlorine is completely absent in this substance, which many plants are afraid of. As a result, potassium nitrate can be used for the following garden crops:

  • potatoes,
  • carrot,
  • beet,
  • raspberries,
  • blackberry,
  • most types of ornamental plants,
  • some varieties of fruit trees.

It is noted that potassium nitrate is a substance especially useful for such a culture as cucumbers. It is especially useful to apply this dressing during the fruiting period of this vegetable crop. There is an increased yield of vegetables, but this decreases the active growth of greenery. This is the main advantage, as the rapid growth of greenery only takes all the necessary nutrients from the plant.

It is advisable to use potassium nitrate for tomatoes.. Here are the best properties of fertilizer:

  • accelerated photosynthesis,
  • the root system is significantly strengthened,
  • yield increases.

Основной особенностью использования калиевой подкормки является возможность ее применения на протяжении всего сезона.

According to the latest figures, the use of potassium nitrate does not affect the development of some garden crops. For example, this feeding will be ineffective for potatoes, radishes, cabbage and greens.

General recommendations

Although potassium nitrate and easy to use, but in the application it requires compliance with some simple, but very important rules:

  1. Before using the fertilizer, be sure to dilute it with water.
  2. In no case can not be diluted with this substance with organic fertilizers such as peat, straw, manure or sawdust.
  3. It is not recommended to fertilize plants with potassium nitrate very often. You can do feedings no more than 3 or 4 times, but in most cases, enough and 2 watering.
  4. While working with potassium nitrate, you need to follow some precautions: wear rubber gloves and goggles. Since nitrate fumes are unsafe for human health, the presence of a respirator is mandatory.
  5. If during treatment of plants with potassium nitrate, a substance accidentally gets on the skin, it is necessary to immediately wash the affected skin with water and treat it with an antiseptic.

Thus, potash nitrate or potassium nitrate is one of the few organic fertilizers that deserve universal recognition and popularity. Thanks to this category of fertilizers, many gardeners, gardeners and farmers get a very good, high quality and bountiful harvest.
