Soil agrochemical analysis often shows a high content of potassium, and farms often don’t pay enough attention to this element, especially when it comes to foliar fertilization. However, neglecting potassium in the fall is not an option, and here’s why:

• High potassium content according to agrochemical analysis usually shows gross content, not available, as its extraction from the soil is done by aggressive substances.
• The situation is similar to phosphorus and other elements in the fall: the root system is underdeveloped and not working at 100%, plus there are several factors that limit their absorption.
• Potassium also has various functions: it is a catalyst for many physiological and biochemical processes, participates in the formation of high-energy compounds (ATP), which contributes to a quick start and further accumulation of vegetative mass; actively participates in the absorption of water and mineral substances by plant roots, in the transport of assimilates between organs, activates enzymes that accelerate the synthesis of proteins and carbohydrates, which is particularly necessary for young shoots.
• Accumulation of additional carbohydrates and sugars in plant cells before wintering is crucial for creating conditions for optimal overwintering.

Therefore, by foliar fertilization with potassium, we can not only additionally prepare winter crops for overwintering but also create conditions for future harvest (increased disease resistance, better restoration of vegetation in spring). That’s why complex NPK fertilizers with an emphasis on phosphorus and potassium are precisely what winter crops need for foliar fertilization in the fall.
