Soybean is a crop from legume family and it has ability to form symbiosis with beneficial microorganisms in the soil. These microorganisms fixate atmospheric nitrogen and transform it into accessible form for the cultivated plants, nitrate nitrogen. Due to this it is very important to pay attention how much nitrogen is given through the basic fertilization before sowing, i.e. to reduce the quantity of the basic fertilizer during soil cultivating, and add all other necessary quantities of nutrients during vegetation through FITOFERT foliar fertilizers. Boron has a multiple effect on soybean crops: it affects root growth, improves nitrogen fixation, stimulates branch spread and flowering, prolongs longevity and fertilization of the flowers and increases the number of beans in the pod.
