It is considered one of the most important problems in land reclamation is the assessment of soda salinization of soils. On the basis of long-term research on the genetic and meliorative properties of the Western Siberia soils, methodological approaches have been given to assessing soda salinization of soils. In the assessment methodology, along with the principle of sodification (congestion and accumulation of soda), depending on the quality of irrigation water, where the processes of metamorphism of the systems of salts and solutions and waters proceed only under the condition ensuring of the forming systems CO3 + HCO3 > Ca2+ + Mg2+, is used the method of soil resistance evaluation. Soil resistance reveals their immunity to soda salinization. Such geosystem evaluation of soil soda salinization has proved its ecological and economic efficiency, revealing the full range of their genetic and land reclamation features. |
