The Role of Agro-Ecological Land Evaluation in the Adaptive - Landscape Farming Systems of the Kazakhstan Dry Steppe Zone
As result of studies it is shown that agro-ecological land evaluation is important for crops selection in fodder rotations on account of their different yielding capacity. This is indicated by the evaluation coefficients of forage crops productivity according to the agro-ecological land subgroups (1,05 - 2,34). Differences in soil subgroups grade assessment (18,4 - 24,5) and their agro-ecological qualities (0,55 - 0,80) are demonstrated.
