The article presents three-year data on the influence of different fertilization systems and predecessors (corn for silage and peas) of winter wheat in the rotation on the dynamics of content in the 0-20 cm layer of black leached soil of mineral nitrogen, of available phosphorus, of potassium, and yield of winter wheat. The materials presented in this article indicate that, regardless of its p ...

Great practical and theoretical interest comes with a study of the transformation of calcium agrobiogeochemical in agro-ecosystems. The basis of the stability of the soil, as an element of the structure and functioning of the biosphere, constitutes historically approved biochemical cycles and flows of matter and energy, which remain unchanged under anthropogenic impact. Comparative analysis of ...

The results of study of groups and forms of iron compounds in leached chernozemic soils of Western Ciscaucasia for three crop rotations according to scheme grain-grass-hoeing are presented. With long-term use of leached black soil in terms of Agrigento there is a substantial change in the contents of the various groups and iron compounds. On the non-fertilized variant of rotation, the total co ...
