Crop yield and potassium sulphate

In agriculture, a large number of different fertilizers are used. For effective use of sod-podzolic and peat soils, potassium is introduced into them. But such fertilizer is also used on chernozems - for crops that need to absorb a lot of potassium and sodium: sunflower, sugar beet, roots, vegetables.

Potassium sulfate is used as a chlorine free fertilizer for root and radical bait. Its use is due to the type of crop, the technology of cultivation and the content of potassium itself in the soil. Such a fertilizer affects the yield more effectively when applied in combination with phosphorus fertilizers. To increase the content of sugars and vitamins in plants, potassium sulfate is used. Hydrolysis does not occur, but the substance dissolves well in water, so the fertilizer is applied in the form of aqueous solutions.

In early autumn, for fertilizing plants make a solution of nitrogen-free fertilizers, in which potassium sulfate is added. The use of such a solution helps to increase the winter hardiness of trees and shrubs. Potassium sulfate is introduced under all garden crops, it is used for room or balcony flowers. This fertilizer is suitable for any application: the main - in the digging of soil in autumn or spring, as an additional food - during the entire growing season.

On sites with humus soil and with reduced humidity in the summer, the fertilizer doses are lower, on low-fertile soils, with sufficient humidity, higher.

First of all, potassium sulphates are used for chlorine sensitive crops - grapes, potatoes, citrus fruits, tobacco, flax and others. Fertilizers with sulfate ions positively influence the yield of legumes, cabbage, rutabaga and turnip.

Potassium sulphate is a concentrated fertilizer with a high content of potassium oxide, which is not caked or hygroscopic. It is effectively used not only in the open, but also in the closed ground (in greenhouses).

After entering the soil, the fertilizer quickly reacts with the soil complex. When digging soil for cucumbers, tomatoes, strawberries and flowers, make no more than 20 grams per 1 sq. M. Soil, cabbage beds, beets, potatoes and carrots - up to 30 grams. For fruit trees and shrubs, it is required to apply up to 200 grams of fertilizer per pit during planting.

During the vegetative period, grooves up to 5-7 cm deep are made to fertilize vegetable crops and up to 15 g / m2 of fertilizer are applied in them. The use of potassium sulphate is necessary not only during the ripening of the crop, but also for a number of perennial plants after harvesting fruits, for example, strawberries, strawberries, fruit trees and shrubs.

When fertilizing plants in the spring for a varied and balanced diet, together with potassium sulfate in one solution, phosphorus and nitrogen fertilizers are applied. During the ripening of the crop and at the end of vegetation, in combination with potassium fertilizers only phosphorus fertilizers are used.

But the use of other fertilizers in combination with potassium is not always recommended. So, you can not categorically mix potassium salt, potassium chloride or potassium sulfate with chalk, lime, dolomite. This can lead to the death of plants.

When working with potassium sulfate, respiratory protection (respirators) should be used as a fertilizer, impermeable (rubber) gloves or mittens for hands, and for eyes - goggles, as the action of the chemical is irritating. It is advisable not to be in rooms with a high concentration of potash dust, avoid prolonged contact with the fertilizer, while observing the rules of personal hygiene - with prolonged ingress of dust into the human body, poisoning is possible.

In a number of European countries that are part of the European Union, potassium sulfate is allowed as a food supplement (ingredient E515).
