The issues of soil fertility preservation are relevant in all countries of the world. There are proposed concrete actions, technological and organisational solutions allowing to overcome this complex and continuous phenomenon by using exclusively agroengineering approaches. The preservation of the structure of agricultural soils requires urgent adoption of technological and organisational decisions in the following areas: maximum limitation of immobilisation of nitrogen in the soil after introduction of organic residues into the soil; development of technological methods and tools for the soil cultivation, aimed at loosening the surface layer of the soil with a minimum area of its contact with the airborne environment; improvement of the fundamentals of aggregation of agricultural machines, taking into account the maximum permissible slipping of wheeled energy facilities at the level of 15%, and a conceptual approach to their ballasting with respect to the requirements of the tire ecophilicity; application of a soil structure indicator when determining the ploughing frequency by means of ploughs with skimmers or their two-tier analogs; wide practical application of the controlled traffic farming system; adoption of a legislative document on specific conformity of the land users for the level of soil fertility for agricultural purposes.
