Microfertilizers and special fertilizers
Microfertilizers – fertilizers, containing micronutrient elements and substances consumed by plants in small amounts. They are divided into boric, copper, manganese, zinc, cobalt and other, as well as polymicrofertilizers composed of 2 or more micronutrient elements. The most effective forms of micronutrient elements are chelates (Zn, Cu, B, Mo, Fe, Co) and other compounds as part of organic molecules (boretanolamin etc.).
