On modeling the connection of the soil structure With the content of organic matter And exchangeable cations Ca2+ and Mg2+

Abstract

A method is proposed to evaluate the connection of contents of organic matter (humos) and exchangeable cations in the soil adsorbing complex with the number of micro-aggregates determining the soil structure. The method is based on the use of statistical analysis of joint data of water extracts and the number of microaggregates in soils (serosems and black soils). The method is expected to allow a more complete assessment of the impact and effects of irrigation on the structure of the soil layers.
