Current weather and temperature conditions allow for foliar fertilization of winter oilseed rape. Plantations sown on time have reached the 6-8 leaf development stage and require a procedure to modify the plant habit. Foliar fertilization with microelements can be used in the same procedure. This will allow plants to properly develop a root system. This will optimize the uptake of nutrients such as phosphorus, nitrogen, potassium and microelements. Plants will also increase their resistance to abiotic stress associated with overwintering. Plantations sown later and those that have recently been exposed to the effects of excessive rainfall will additionally require the supply of phosphorus and potassium in the form of foliar fertilizers. This will allow plants to maintain the correct growth rate.
