During the last 40-50 years, the surface of the eroded soils of the Republic of Moldova increased by approximate 284 thousand ha, or annually by 7 thousand ha. The annual damage caused by erosion is estimated at 200 million US dollars. The problem of restoring the fertility of soils degraded by erosion under current farming conditions can be solved by using local organic fertilizers, which can serve to maintain and increase soil fertility, and not as environmental pollutants, which occurs in most cases. Being used as organic fertilizers, they increase the productivity of agricultural crops by 30-40%, reduce the humus deficit by an increase of 150-200 kg/t. Organic fertilizers applied to eroded common chernozem improve the quality of the structure and the aero-hydric regime of the soil. The use of local organic fertilizers also has a positive impact due to the fact that they are directed to study and applied according to the recommendations for their integrated exploitation in agriculture where they have origins.
