When using long-term haymaking (73 years of use), the regularities of the influence of fertilizers and technological systems on the productivity and fertility of the soil are established. When using a technogenic system (without fertilizers), the productivity was 31.9 GJ/ha of exchange energy, the content of mobile phosphorus in the soil decreased by 37%, exchange potassium-by 19%, humus increased from 2.03 to 3.05%, with an annual humus content of 18 kg/ha. The highest productivity of haymaking over the past 27 years of use was observed in the technogenic-mineral system when using N180P45K90 —– 72.5 GJ/ha of exchange energy, 5.6 thousand feed. units, 922 kg/ha of raw protein. The content of mobile phosphorus in the soil increased by 232% compared to the initial one, humus from 2.03 to 2.94%, exchange potassium decreased by 18%, and the average annual accumulation of humus was 28 kg/ha.
