Biological cycle of organic matter and elements of plant nutrition in the field crops on the chernozem
Abstract
In the stationary experiment of NSC «Institute of Agriculture of NAAN» carried out on the chernozem of Panfilskaja experiment station, plant biomass and the content of chemical elements (nitrogen, phosphorus, potassium) in it, the organic mass in plants and nutrition elements estranged with crops and applied into soil with plant residues were determined. This makes it possible to estimate the importance of crop in crop rotation and its influence on cultural process of soil development.
