Agroecological assessment of agricultural land management and measures for its protection

In the study complex agroecological research of the condition of dry steppe landscapes of Altai Region was conducted. It was shown that in dry steppe of Altai Region agroecological condition of lands depended on geological and geomorphological features and bioclimatic potential. The complex of actions for protection of lands of agricultural purpose was complicated by the dependence on agroecological condition of natural and anthropogenous factors influencing the stability of agrolandscapes and the level of agricultural production. On the basis of agroecological assessment of chestnut soils of agrolandscapes of dry steppe Kulunda the following complexes of actions keeping geosystems were developed. The first complex optimized agrolandscapes: the main action of this complex was the creation of the system of field-protecting forest plantings. In combination with forest plantations on flat alluvial sandy loam plains and slopes of loess plateaus, other phytomeliorative techniques were relevant, for example, leaving straw residues (mulch), occupied and green manure fallows, tinning, soil-protective crop rotations with band placement of field crops, annual (legume) and perennial grasses...
