Abstract:
In the natural regime, the dynamics of the structural - aggregate state of the soil is determined by the volumetric, swinging - shrinkage changes materialized in apparent density and penetration resistance. In agriculture, the structure is determined by the specified factors, but also by a number of technoantropic factors: the system of work, the terms and conditions of carrying out the works, the fertilization system and the maintenance of the crops. In order to maintain the structural state of anthropogenic soils, it is necessary to use organic fertilizers that serve as raw material for the formation of humus as a degrading factor in maintaining the soil structure.
