Change of water-physical properties of mountainous meadow-chernozem soils of the republic of Armenia under the influence of anthropogenic factor

The aim of the article is to study direction negative changes in water-physical properties occurring meadow-chernozem soils under influence anthropogenic factor. "soil keys" method was used determine location transects. Field researches were conducted on same-type relief areas, when comparing virgin and arable variants soils. Soil samples taken from main sections by genetic horizons. In results research factors change mountain Republic Armenia are presented. At present stage issues storing improving fertility mountainous very acute. These soils, long-term use agricultural crops, undergo considerable deterioration, leading activation degradation processes Long-term unsystematic leads increase their density. porosity, its moisture capacity, mechanism movement, etc. depend soil studies have shown that density tilled layer generally favourable for growth development plants, but upper part profile somewhat compacted variants. data porosity show studied characterised satisfactory general porosity. High especially whole-loam some deterioration water observed. maximum hygroscopicity, field range active content stable wilting slightly decrease.
