Studies of the effect of litter chicken manure applied in doses of 500-1000 t/ha showed a significant increase in the humus content in soils up to 2.8-5.2%, led to an increase in the content of thermophilic microflora in soils up to 12 · 105 CFU/ g, to an increase in the content of mobile phosphates up to 1200 mg/kg. However, the content of mobile forms of heavy metals (Pb, Zn, Cu, Ni) also increased. The increase in humus content in soils positively correlated with the content of mobile phosphates (r up to 0.5).
