Summary: The article focuses on rapid intensification of operational loads on agricultural land, which is caused by a number of factors such as: population growth and the increasing of world food prices, the reduction of agricultural
land in world space, environmental degradation and an increase of negative anthropogenic influence in general. The significant importance of organic fertilizers in modern agriculture is determined and the method of determining of the optimal organic-mineral nutrition of crops on cereals example is generalized by the experimental way. The current state of the livestock industry with distinction of trends of rapid reductions in the number of
animals with corresponding consequences for the total emission of organic fertilizers is analyzed. The dynamics of organic fertilizers using is studied, which revealed a clear downward trend. On this basis, the amount of nutrient loss was calculated in equivalent amount of mineral fertilizers and a potential grain crop. The most rational option of animal waste treatment is substantiated, which involves pre-bio-fermentation with simultaneous separation of biogas and fertilizers, which will enhance the ecological-economic efficiency of using animal manure. Recommendations to provide the required amount of organic fertilizers by establishing a minimum allowable
quantity of animals per unit area of arable land have been made, multiplicative ecological and economic effect of this option was calculated.
