Instructions for the use of potassium chloride in the garden

Potassium chloride is a fertilizer that contains a lot of potassium. It is used in agricultural technology in order to replenish nutritional components and stabilize the development of crops. Used together with other feed formulations, combined with nitrogen- and phosphorus-containing fertilizers, or separately. Today, such fertilizer is considered the most popular among gardeners.

What is Potassium Chloride

It is a concentrated potassium supplement. Based on the method of production and classification according to the requirements of the standards, the fertilizer can contain from fifty two to ninety nine percent of potassium.

It looks like granules or crystals of pinkish, white, gray and even brown shades. Formed during the reaction of potassium hydroxide with hydrochloric acid under laboratory conditions. In production, the main raw material is salt, which contains potassium.

Under natural conditions, the substance is contained in sylvinite, it can be found in the form of sylvine and carnalite.

Potassium is considered to be the most important component in the nutrition of crops.... It differs from nitrogen and phosphorus in that it is included in the organic composition of the plant. For this reason, fertilizers have to be added to the beds additionally.

Why is potassium chloride good as a fertilizer?

Many plants can survive micronutrient deficiencies, reducing productivity or stopping fruiting., but an insufficient amount of one of the main components causes the death of the culture. This means that on the beds of the personal plot, feeding with the main nutrients should be carried out constantly.

The peculiarity of potassium chloride is that it is contained in minimal amounts almost everywhere and can be replenished from natural sources. To be honest, gardeners discovered this fertilizer relatively recently. But it turned out that it is an excellent help in the garden and has a multifaceted effect on plants.

It accelerates the growth and development of root systems, increasing their resistance to frost and drought, activates the formation of shoots, increasing yields, and improves the quality of fruits.

Properties and benefits from application

It is believed that potassium chloride does not need to be used in fertile soil. But this is not so - in such areas it is allowed to minimize or not use nitrogen and phosphorus at all, but potash fertilizer will definitely be needed. With its help you can:

  • improve the immune system of plants, prevent many diseases;
  • increase frost resistance of perennials;
  • help plants better tolerate temperature changes;
  • reduce the likelihood of dehydration;
  • have a positive effect on the formation of the yield, especially for tuber crops;
  • improve the presentation of the product and its taste;
  • to extend the shelf life of the crop.

Potassium chloride can often create overfeeding of plants. In perennial crops, this is expressed in the disease of the root system, freezing of the kidneys in winter. Annual plants immediately lie down and begin to rot near the root collar.

Long-term use of fertilizer will negatively affect the condition of the soil - it becomes acidic. In addition, due to potassium chlorine, a large amount of salt accumulates in the earth.

Fertilizer application in the garden

Potassium chloride is not introduced in the winter, it is used only in the summer. It is used for:

  • urgent foliar feeding;
  • heavy soil composition during spring digging of beds;
  • preparation of perennial crops for the winter season;
  • seasonal plant feeding, well assimilating this fertilizing composition;
  • planting crops that consume excessive potassium chloride.

It is possible to fill the soil with potassium chloride in the fall before the winter season in clay and loamy places where a lot of snow falls.

This fertilizer is recommended for use on sandy, podzolic, sandy loam and peat soils, where good yields can be achieved only by introducing nutrients.

Compatibility with other fertilizers

Simultaneous use with lime, chalk or dolomite flour is prohibited. It is allowed to combine fertilizer with ammonium sulfate, manure, ammophos, chicken droppings, diammophos.

Immediately before use, the substance is mixed with urea, ammonium, calcium, sodium nitrate, superphosphates.

Storage and precautions

As follows from the instructions, potassium chloride is a moderately hazardous substance. It does not have a negative effect on the integrity of the skin, but it prevents the healing of wounds, irritates and can contribute to inflammatory processes.

Therefore, it is recommended to use protective clothing when working with such a fertilizer composition, covering open wounds and injuries. When combined with air, the substance does not create toxic compounds that are dangerous to the body. It is not considered flammable and explosive, does not form corrosive processes.

High levels of hygroscopicity of the composition are prescribed to store it in a closed room with a low level of humidity. Precipitation and groundwater flooding are not allowed. On the street, fertilizer is stored in tightly sealed containers or in plastic bags. The plot must be under a canopy.

According to the requirements of state standards, the shelf life of the drug should not exceed six months. After this time, the fertilizer loses its external data, forms lumps, but at the same time retains its chemical indicators completely.

Experienced gardeners note that the use of potassium chloride is possible even in emergency situations. Signs of its deficiency in this case are wrapped foliage, brown spots between the veins, drying out.

Correct and timely fertilization will help keep crops growing and producing good yields.

Potassium chloride as fertilizer: description and instructions for use

I took chemistry at school for "5", but I did not know at all - still, we had a former pioneer leader who read this subject, who simply hated chemistry!

But when I seriously started gardening, I had to scratch the turnip thoroughly, since most modern ways to squeeze the maximum yield out of a meter of square soil are not based on organic matter, but on bags with man-made feeds.

Which one is considered natural and which is toxic and why? And most importantly, which of them gives real results? In the case of potassium chloride, everything turned out to be more or less simple.

General information on fertilization

Substance formula - (NH2)2CO, chemical name - carbonic acid diamide. It is obtained from ammonia and carbon dioxide. Urea has a crystalline structure and is usually granulated during production. Granules 2-3 mm in diameter, colorless or white, odorless. They are slightly hygroscopic, but well soluble in water, and can be transported without problems. They must be stored in plastic bags, granular urea does not stick together, almost does not cake. The fertilizer belongs to the 3rd class of hazardous substances (moderately hazardous), you can work with it without protective equipment.

Urea contains 46% nitrogen, more than any other nitrogen or mixed fertilizer. The element is in the amide form, it was found that in this type of plants it is poorly assimilated. The rate of conversion of nitrogen into the mineral form is influenced by the temperature and reaction of the soil: in warm and neutral soil, the process is fastest, in cold, acidic or alkaline, it slows down.

Granular urea contains biuret, this substance, if it is more than 3%, can inhibit and poison plants, especially sprouts. In urea, it should be no more than 1%, however, this figure is usually not exceeded in the fertilizer produced by the industry.

Beneficial features

Fertilizer urea used in the garden has a number of advantages, ranging from economic benefits to benefits for plants. Unlike other nitrogen monofertilizers, it is much cheaper. Compared to ammonium nitrate, it is required 3 times less, and there are more opportunities for use, because nitrate is used only for introduction into the soil, and urea - into the soil and by the foliar method.

In addition to increasing the yield, the solution has the following useful qualities:

  • It is used to control pests of agricultural crops and fruit trees. It is applied by spraying on the leaves.
  • When foliar method does not cause leaf burn. Different concentrations are used for feeding and preventing diseases.
  • It is quickly absorbed by plants, which makes the solution a fertilizer of paramount importance in case of nitrogen deficiency. The exposure occurs within the first two days.
  • It is washed out of the soil for a longer time, therefore it is advantageous to use carbamide on sandy and sandy loam soils, on which other dressings immediately go to the lower horizons and plants cannot get them.
  • Safe for the human body.
  • Does not acidify the soil, so plants can receive other nutrients in full.

The absence of chlorine in the composition of urea makes it possible to apply fertilizer in the garden for all plants.

Instructions for the use of fertilizer potassium chloride

1. Use potassium chloride for plant nutrition if you want:
- to increase the resistance of cultivated plants to changeable weather conditions, diseases and various kinds of pests
- to raise the quality and quantity of the crop
- provide long-term storage.

2. Please note that in order to use this type of fertilizer successfully, you need to understand that efficiency depends not only on the characteristics of the soil, but also on the biological properties of garden crops. Chlorine, unfortunately, has a negative effect on all plants. Among the most sensitive representatives to such an influence are tomatoes, potatoes, cucumbers, currants, raspberries, strawberries and salads.

3. Know that you can make chlorine safe in this case. Fertilize your garden crops with potassium chloride only within the allotted time frame. In the fall, apply it to medium to heavy soils. In this case, the chlorine will be washed out by rains from the upper layers in the fall, and then in the spring. Potassium, on the other hand, will remain in the ground and will be useful for plants in the next season.

4. Apply potassium chloride in the spring to light and high peat soils. If fertilized in the fall, a noticeable loss of potassium cannot be avoided. On such types of land, he lingers a little. Therefore, experts recommend that vegetables sensitive to chlorine be fertilized with potassium magnesium or potassium sulfate.

5. Keep in mind. Potassium chloride is presented in the form of a fine-crystalline and coarse-crystalline substance of gray or pink shades. Large granules are most effective. They take longer to dissolve than small ones, and therefore the nutrient potassium in them will be available for plants longer.

  • Strengthens the immunity of plants, increases frost and drought resistance.
  • Promotes moisture retention in the soil, prevents dehydration of plants.
  • Stimulates tuber and fruit formation.
  • Improves the appearance and taste of the fruit.
  • Increases the shelf life of the crop.

They are brought in in the fall for digging the soil. The norm is 100-200 g per 10 square meters of soil.

In the spring, the rate is reduced to 25-50 g per 10 sq. M.

Instructions for the use of potassium monophosphate in the garden

Top dressing should be carried out with a working solution of potassium monophosphate. The composition is used for watering the soil or irrigating the ground parts of plants. The procedure should be performed in the evening to slow down the evaporation of liquid. Also, the composition can be used in drip irrigation installations.

After prolonged precipitation, there is a need for emergency feeding. Thanks to this, it is possible to replenish the supply of potassium, which was washed out from the aboveground fragments of crops. There may also be a need for calcium supplementation.

To achieve the desired results, it is worth adhering to the dosage of applying the funds:

  1. For seedlings of vegetables and flowers, it is recommended to use 7-10 grams per 1 bucket of water. In this case, it is required to carry out 2 dressings. For the first time, the composition is applied at the stage of appearance of 2-3 leaves. For 1 square meter of planting, 3-5 liters of solution are used. The second time, it is required to apply the composition 10-15 days after diving or transplanting seedlings into open ground. After the appearance of 5-6 leaves, it is permissible to increase the dosage to 5-10 liters per 1 square meter.
  2. Vegetables require 2 dressings. The first time, the manipulation is carried out at the beginning of fruiting, the second - after 15-20 days. At the same time, 5-10 liters of working fluid must be used for 1 square meter of beds.
  3. For feeding ornamental bushes and fruit and berry crops, you need to make a solution of 10-15 grams and 10 liters of water. A total of 3 dressings are recommended. For the first time, apply the composition after flowering, the second - after 15-20 days, the third - in mid-September. At the same time, 10-20 liters of the substance should be used per 1 square meter.

There are also certain features of making fertilizers for specific plants:

  1. It is recommended to feed tomatoes with a solution of 15% concentration. To prepare it for 10 liters of water, you need to take 15 grams of top dressing. The seedlings should be treated twice during the season. This is done at intervals of 2 weeks.
  2. Cucumbers should be fed in the same way as tomatoes. But there are also some differences. The dosage of the product depends on the shape of the fruit. If they are deformed, then it is necessary to make top dressing.
  3. Potatoes require irrigation of the tops. To do this, you should use 10-15 grams of granules per 1 bucket of water. Apply in the morning or evening. The first time it is done after hilling, the second - when buds appear. Thanks to the use of fertilizer, potato tubers become denser and larger. In addition, the composition significantly strengthens the tops. Thanks to the introduction of monopotassium phosphate, the shoots do not fall on the ground.
