MIGRATION OF MICROELEMENTS IN SOILS OF FERGHANA VALLEY AND ADVANTAGES OF USING THEM

The role of microelements in physiological, biological and chemical processes in plants is extremely high. The soil is a source of microelements for plants, animals and people. Microelements include vitamins, enzymes, and hormones. The lack or excess of microelements in the soil leads to a decrease in crop yields, deterioration in the quality of agricultural products, metabolic disorders and, in some cases, causes endemic diseases of plants, animals and people. Migration of microelements in living organisms is carried out in the system soil → plant → animal → human. Mineral fertilizers are used to provide plants with microelements, they are called microfertilizers because they contain trace elements. Obtaining high-quality agricultural products, the elimination of endemic diseases of animals and humans is achieved by defining areas with insufficient, optimal or excessive content of trace elements in the soil. Microfertilizers are a powerful tool that can regulate the composition of trace elements in the soil
