Humus condition of usual black earth in natural anthropogenic landscape of Kamennaya veld (steppe)



Humus condition of usual black earth in natural anthropogenic landscape of Kamennaya veld (steppe)



Izvestiya Timiryazevskoi Sel'skokhozyaistvennoi Akademii (3): 38-46



Original experimental data characterizing general laws of black earth humus matter structural changes under the influence of anthropogenesis are given in the article. More material changes happened to both humus content and its reserves. Active dehumification of ordinary black-earth is observed. From all variants the most favourable conditions for humus formation are found in the system of black earth irrigated crop rotation of perennial grasses, though the mobility of humus matter goes up when irrigating.
