Abstract

This article discusses changing the basic parameters of fertility (humus, mobile phosphorus, exchangeable potassium, soil acidity) in the conditions of application of increasing doses of sewage sludge.The study demonstrated that the addition of increasing doses of sewage sludge from 5 to 30 t/ha of dry matter results after three cycles of their introduction into the soil to increase the humus content, increase of available phosphorus in the soil, since application rates SALT 5 t/ha of dry matter, but does not significantly increase the content of exchangeable potassium in the soil. Adding doses of sewage sludge of more than 10          t/ha of lime shows its effect and leads to higher values pHsal. The article indicated calculations shift indicators of fertility of sod-podzolic sandy loam soil when making increasing doses of sewage sludge for three cycles of making rain, which can be used for prognostic calculations change fertilityparameters of sod-podzolic sandy loam soil in the conditions of application of different doses of sewage sludge.
