Regular withdrawal of part of the biological products from the crop leads to the fact that mineral substances do not return to the soil during the natural biological cycle. Therefore, agroecosystems are unstable. Maintaining the biological cycle in agricultural systems contributes to their high biological diversity. For this, properly balanced agricultural systems, in addition to fields, also include pastures, hayfields and livestock complexes. This is also facilitated by the organization of crop rotation, during which crop rotation is carried out in the fields.
