Abstract

The problem of anthropogenic changes in the agrochemical, chemical and physical properties of dark-chestnut carbonate soils of the Northern Kazakhstan as a result of extensive use in agriculture is considered in the article. It was analyzed the characteristics of degradation processes and their estimation. There was a decrease of humus content, gross forms of nitrogen and phosphorus. The amount of absorbed bases also showed a decrease in direct correlation with the size fraction (<0.001 and 0.01 mm). It was identified and justified the need to develop techniques to restore the potential and effective soil fertility. An analysis of the closest to the target recovery methods of soil humus is given. An objective assessment taking into account the actual organizational and economic, agronomic and technological features and capabilities are shown. The necessity of a comprehensive approach to the restoration of the potential and effective soil fertility with the use of traditional and new approach, a focused management approach soil fertility in relation to the zonal conditions, allowing at the same time to solve two major problems - the restoration of soil fertility, and the optimization of supply, which ensures high efficiency and environmental safety the use of chemicals was justified.
