Abstract
Goal. To determine the influence of organic and organo-mineral systems of fertilization and soil cultivation on the transformation of the humus state and the agrochemical properties of typical black soil. Methods. Field, laboratory. Results It has been established that prolonged application of different fertilizer systems for combined and shallow soil treatments causes differentiation of the upper layer of soil by the level of humus, qualitative changes of organic matter and the agrochemical properties of typical black soil. Conclusions The use of fertilizers contributed to the increase of mobility of the whole system of humus substances, which is confirmed by the growth of the content of moving fractions and the decrease in the content of fractions that are tightly bound to the mineral part of the soil. Organic and organo-mineral fertilizer systems for combined and shallow soil treatments have positively influenced the nutrient content.


Key words: fertilizer systems, soil cultivation, typical black currant, humus, nutrients.
