Determination of Ecologically Acceptable Technology for Cultivation of Agricultural Crops on Leached Chernozem in the Western Ciscaucasia

Abstract

The Western Ciscaucasia, which occupies the flat part of the Krasnodar Territory, is a unique natural site of the Southern Federal District of the Russian Federation. The soil covering of this region is characterized by domination of fertile super-deep and deep Kuban chernozems. However, their intensive use has led to an imbalance between their effective and potential fertility, as evidenced by a decrease in humus reserves and a worsening of its qualitative composition; depletion in nitrogen, phosphorus, potassium, calcium; acidification; heavy metal pollution; and, consequently, an ecological imbalance in the soil–plant system.
