HUMUS STATE TRANSFORMATION OF THE RECLAIMED SOLONETZ-SOLONCHAK SOILS OF ARARAT VALLEY DURING THEIR AGRICULTURAL USE
Abstract
The effective use of soil resources largely depends on the content, composition and reserves of humus, which characterizes fertility, agro-industrial properties and productivity of soils. The changes in some of the basic chemical, physical-chemical properties and humus state of soda solonetz- solonchaks, meliorated solonetz -solonchaks and irrigated meadow-brown soils of the Armavir region in Ararat valley are investigated. In a relatively short period of time, improvement in the basic properties of soils is observed, which positively affects their humus state. The reclaimed solonetz-solonchaks become closer to irrigated meadow-brown soils in their desalinization and dealkalization rate, salt content, CO32-, pH, water-soluble and absorbed sodium, as well as in the composition of humus cluster.
