Appointment, types and features of the use of potash fertilizers

Potash fertilizers are minerals. They are widely used as a source of potassium for top dressing indoor plants and are needed for nutrition of garden crops. Regardless of the composition, dilution instructions must be strictly followed.

Why garden and indoor plants potassium

Potassium contained in fertilizers is of great importance in the growth and development of garden and indoor plants. Potassium top dressing allows the productive use of water, and also improves the movement of nutrients in plants and contribute to good root development. Such an element is necessary for garden plantings, so that the ripening fruits acquire a brighter coloras well as pronounced aroma. Harvested crops not only look attractive, but also stored for a long time.

Fertilizing fertilizers, which contain a sufficient amount of potassium, is necessary for plants at the stage of activation of growth processes and crop formation, and also have a positive effect on the resistance of crops to drought, low-temperature regimes, damage by plant parasites and fungal diseases.

To understand what top dressing is not enough, you need to remember that a clear deficiency of the element causes a slowdown or stop of growth, shortening of internodes on the emerging shoots. In addition, foliage can be deformed, yield and resistance to adverse external factors can decrease.

Purpose and use of potash fertilizers

There are different types of potash fertilizers, and in order to determine which ones are appropriate for each particular case, it is necessary to familiarize yourself with the characteristics of such top dressings and the rules for their use. Potash mineral fertilizers are responsible for the taste characteristics of the crop, the development of leaves and the level of resistance of vegetables, ornamental and horticultural crops:

  • improving the natural immunity of plants;
  • increase of protective functions.

It should be notedthat such elements are perfectly combined with many mineral complexes, and their digestibility is quite high in almost any culture. However, excess potassium is also very harmful, and causes growth retardation, shredding and browning of the foliage. Excessive intake makes it difficult to absorb calcium, magnesium, zinc and boron. Unnaturally plentiful flowering is sometimes observed with the subsequent formation of small fruits.

Varieties of potash fertilizers

Types of Potash Fertilizers

The substance is gray, white or creamy pink in the form of powder or crystals. A feature of potassium chloride is the good digestibility of decorative and flowering crops. It is allowed to mix with almost any kind of chemical elements.

Components can be applied to many types of primers. Potassium chloride is water-soluble, but may coalesce. Potash components excellently acidify the soil and are optimal for application after liming. A good result is the introduction of potash fertilizers for decorative cereals.

Chemical industry products

The general global trend is the expansion of production volumes for the production of complex types of fat in the form of double nitrogen-potassium and phosphorus-potassium complexes and triple nitrogen-phosphorus-potassium fertilizers. By the method of release, such a component is called:

  • complex tuks;
  • mixed tuks;
  • combined tuks.

The first option can be represented by potassium nitrate, well water-soluble and not hygroscopic, as well as ammophosphate. The composition of liquid potassium-containing fertilizers is represented by potassium, nitrogen and phosphorus. The second option is obtained on the basis of ready-made components in accordance with established proportions. The combined type of potassium-containing granular fertilizers is produced in the process of acid or ammonia treatment.

The most popular formulations:

  • potassium nitrate represented by grayish-white crystals with a yellowish tinge. The crystals dissolve well in water, and the resulting solution can also be used after the formation of ovaries, for feeding root crops, berries and tomatoes. It is allowed to use in a dry form. The last time you should feed the plants a month before the harvest;
  • kalimagnesia It is a complex potassium-magnesium fertilizer, non-chlorine-containing, hygroscopic, non-caking. Such a composition has proven itself very well in areas characterized by a low content of active magnesium and potato fields;
  • nitrophoska differs in the equal content of nitrogen, potassium oxide and phosphorus and is widely used in any garden crops;
  • nitroammofosk it can be used both scattered, and local application, as well as in the sowing season and for foliar top dressing.

Many gardeners, gardeners and amateur gardeners abandoned fertilizers of industrial production in favor of no less effective natural components.

The use of potash fertilizers in the fall

Derived from natural raw materials

A significant part of potash fertilizers is extracted from the so-called potash ores located in natural deposits. As natural salts, carnallite, sylvinite, polygalite, cainite, Shenit and nepheline are most often used.

An excellent natural potash fertilizer capable of competing well with mineral complexes is the usual wood ash. The main advantage is the presence in the composition in addition to potassium of many important elements in the form of phosphorus, calcium, magnesium, iron, sulfur and zinc.

Valuable for decorative leafy, flowering and horticultural crops, wood ash can be obtained by burning wood. The most valuable is the fertilizer obtained by burning fruit and deciduous, in particular birch wood. Coniferous ash is less useful for plants. Valuable top dressing can be obtained by burning potato tops, sunflowers, cereal straw, including rye, wheat and buckwheat. Such fertilizers can feed almost any plant.

It is strictly forbidden to use the ash obtained as a result of burning household waste, including plastic and rubber, to improve soil and feed crops. Such toxic substances are detrimental to the microflora of the soil and the formed crop.

Instructions for use potassium chloride

Potassium chloride has a high potassium content. The substance is actively used in agricultural technology, if necessary, replenish nutrients and normalize the development of gardening and ornamental crops. It can be used in complex dressings, together with nitrogen-phosphorus components.

Advantages of making:

  • increasing the "immunity" of plants;
  • disease prevention;
  • increased frost resistance of perennials;
  • improved adaptation to temperature extremes;
  • reduced likelihood of crop dehydration;
  • a positive effect on fruit formation;
  • improving the quality of garden products;
  • increase the shelf life of the harvested crop.

It is important to strictly adhere to the dosage recommended by the manufacturers, as excessive application often reduces soil fertility.

Potassium chloride can be granular and fine, as well as differs in varietal characteristics:

  • granules or crystals of the first grade are compressed, irregular in shape, have a grayish-white or brownish-red color;
  • granules of the second grade, represented by large crystals of grayish-white staining.

Terms of use:

  • potatoes, tomatoes and other vegetable crops - making a digging at the rate of 100 g of potassium chloride for every 10 m²;
  • garden plantings - the application of 150 g under one adult fruit tree. Depending on the type of soil, the application rate can vary from 120g to 180 g.

The standard autumn application for digging is 100-200 g for every 10 m² of usable area. During spring application for digging, the dose must be reduced to 25-50 g per 10 m². For feeding during the growing season, solutions are used, prepared at the rate of 30 g per bucket of water at room temperature.

What potash fertilizers to use for indoor plants

If the soil with which the flower pots are filled contains too little potassium, then the decorative indoor plant does not bloom at all or forms too small and unattractive inflorescences.

Also potassium helps plants absorb carbon dioxide from atmospheric air. With an excess of the foliage element, as well as with a deficiency, it very characteristically turns pale or almost completely discolored, which is explained by the difficulty in the supply of nitrogen fertilizers and other important trace elements to plant juices.

To feed indoor flowering and ornamental foliage crops that need slightly acid and acid soil, it is best to use potassium sulfate. Fertilize large household perennials sensitive to chlorine, preferably by kalimagnesia.

When to apply potash fertilizer to the soil

The composition of potassium-containing fertilizers is represented by substances that can perfectly dissolve in water, and when introduced into the soil, a quick reaction with the components occurs. However, chlorine anions are easily washed out of the soil, which must be taken into account in the process of determining the timing of feeding and choosing a dosage.
