Abstract
The article provides information about dynamics of the content of trace elements available in plants copper, zinc, manganese and water-soluble boron under the conditions of a field experiment conducted on irrigated gray-brown meadow soils during the cultivation of winter wheat. The experiment consisted of five options: 1-option-control, without fertilizers; Option 2 - 2 tons of manure on the background of N-220 R-160 K-50; option 3 - 7 t/ha of waste and residues on the background of N-154 R-112 K-35; 4-option-10 t/ha of waste and residues on the background of N154 P-112 K-35; 5-option-15 t/ha of waste and residues. The results of the research have established that the greatest amount of microelements in the soil is observed during the period of winter wheat budding in all variants of the experiment. The introduction of manure, waste and plant residues together with mineral fertilizers contributes to an increase in the content of trace elements of copper, zinc, manganese and boron available in plants in soils.
