Foliar fertilizers and biostimulants provide an additional amount of essential nutrients in an easily absorbable form. The effect is quicker (1-3 days) compared to soil application. Foliar fertilizers and biostimulants can be applied throughout the entire vegetative period, depending on climatic conditions and plant needs. They serve as correctors of nutrient deficiencies, stimulate plant growth and development, and are the basis for achieving higher and better yields.
