K2SO4 is applied in different ways depending on the type of soil. On heavy loams, it does not pass well into the soil complex, and usually turns out to be locally locked in the place of use.

In order for potassium to become available to the roots, it must be used in advance (preferably in the fall), removing the top layer of the earth (10-30 cm, depending on the type of plant).

Another way to urgently feed an already adult plant with this substance is to make pits (vertical holes) around it, at an angle of 45 degrees, towards the roots, and pour the recommended dose of an aqueous solution of potassium sulfate there. For fruit trees, this agrochemical is applied already at planting, to the bottom of the planting pit, together with phosphorus fertilizer.

Application rates will vary from crop to crop. The dosage depends on individual characteristics, and on the amount of potassium intake by one or another plant. The following proportions are recommended for spring digging of land for fruit and vegetable crops:

Tomatoes – 20 g per square meter;

Cucumbers – 15 g per sq.m .;

Cabbage, turnips – 25 g per sq.m .;

Potatoes – 30-35 g per sq.m .;

Berries – 20 g per sq.m .;

For the second feeding, which is done in the middle of summer, you can take a potassium sulfate solution. In this state of aggregation, the active substance will reach the plant roots faster. On sandy soils, you can simply water your plantings at the root, and on heavy loams, it is advisable to feed on a leaf. The solution is prepared as follows – 35-40 g of potassium sulfate is taken for 10 liters of water and everything is thoroughly mixed. Despite the almost complete dissolution of salts, it is better to use this liquid fertilizer immediately, watering with an estimated amount of about 3-4 square meters. beds.

For summer dressings, you can use the dry fraction. This is especially convenient for row planting of plants, between which grooves are drawn, and K2SO4 powder is poured. But under fruit trees, this fertilizer is applied in much larger volumes – about 150-200 g in one near-stem circle. The peculiarity of the use of potassium in this case is that its crystals must be buried in loose soil in the root zone.

Usage: In agriculture, potassium sulfate is a valuable chlorine-free fertilizer. Potassium increases the content of sugars and vitamins in grown products, and top dressing at the end of August-September contributes to better wintering of fruit and berry and ornamental trees and shrubs. It is used on various soils, for all crops, as well as for indoor and balcony floriculture.

Fertilizer potassium sulfate K2SO4 is also particularly effective for grain and oil plants. It improves tillering, increases the thickness of the stem and takes part in all metabolic reactions: it promotes better grain filling, improves its fullness, increases the protein content. By regulating the water balance, the plants become more resistant to drought. Potassium is perfectly absorbed by winter and spring wheat from germination to flowering and most intensively – in the “flag leaf” and “milky spikelet ripeness” phases. And the assimilation of potassium by the sunflower most intensively occurs in the period from the formation of the head (phase “asterisk”) to ripening.

How and when to fertilize potassium sulfate?

Mineral fertilizer potassium sulfate is used for foliar feeding of plants by leaf or through drip irrigation. POTASSIUM SULPHATE can be used alone or in conjunction with a solution of urea or other micronutrient fertilizers, as well as a pesticide tested for compatibility.
