4-10-22 SK is a granulated fertilizer in the mass unlike mixing fertilizers (Bulk). Each major and secondary element as well as the trace elements are distributed in each pellets. Our quality charter selects only raw materials assimilated by plants. 4-10-22 SK is a ternary mineral fertilizer NPK granulated rich in potash. Potash is present exclusively in the form of potash sulphate, which has many interests. Its salinity index is low, which makes it particularly suitable in situations where excess salinity is to be feared (intensive fertilization, location of fertilizer), even more so for crops that are sensitive to it.


4-10-22 SK is low in chlorine, chloride content below 2%. This property is particularly sought after for chlorine-sensitive crops such as vegetable, arboreal, wine or potato crops. It provides sulphur, an essential element for crops, in sulphate form very easily assimilated for plants. Potash sulphate also promotes dry matter production, sugar accumulation and improves crop firmness. There is a significant synergy between nitrogen and phosphorus elements, and nitrogen and potassium: a joint supply of phosphorus and potash allows an increased absorption of nitrogen by the plant.


4-10-22 SK promotes the mineralization of elements stored in the soil. It is enriched with magnesia to strengthen the resistance of plants, fruits, vegetables, trees and shrubs. 4-10-22 SK is distinguished by its great solubility ensuring better efficiency associated with rapid action.
