Increase of an overall production in crop husbandry branch provokes after-harvesting residues rise. For example, maize (Zea mays) cultivated for fodder composes 700 thousand hectares, for grain - 100-150 thousand hectares. After-harvesting residues compile 70-150 centner per hectare. Rape and cereals after-harvesting residues occupy considerable part of the field also. Great volumes of after-harvesting residues make difficult soil cultivation process. Damage of machines (cultivators, ploughs) declines soil cultivation quality and prolongs agro-technical terms. Traditional means of after-harvesting residues dispersal, distribution and burying are not effective and need to be improved. A complex analysis of special aggregates for after-harvesting residues utilization is carried out, comparative characteristic of different aggregates is made. An experimental aggregate for after-harvesting residues utilization is constructed and presented. General view of the field after corn harvesting is shown. Distribution and composition of the corn after-harvesting residues before and after experimental aggregate treatment is analyzed. The results of the research are used during the experimental creation of an aggregate.
