Potassium sulfate, Dnipropetrovsk region.

Potassium sulfate (K2SO4) is the world's most popular chlorine-freefertilizer, which does not contain nitrogen. Potassium sulfate plays an important role in the synthesis of proteins, enzymes and vitamins. Potassium has a positive effect on plants' resistance to drought, low temperatures, fungal diseases, and allows plants to use water more economically. Potassium is responsible for the ripening process of fruits, increases starch content in potato tubers, pectin substances in fruits and berries, and improves the color and taste of fruits. Sulfur, which participates in the process of exchange and transportation of substances, is part of proteins, being one of the starting products for the biosynthesis of amino acids.содержание крахмала в клубнях картофеля, пектиновых веществ в плодах и ягодах, улучшает окраску и вкусовые качества плодов.
