THE ECOLOGICAL STATUS OF AGROSYSTEM WHEN SOIL DISPOSAL OF SEWAGE SLUDGE AND DOLOMITE DUST
In article results of research of soil disposal of domestic and industrial wastes and identification of multi-element anomalies in the soil with the application of sewage sludge and dolomite dust. When soil disposal of sewage sludge and dolomite dust revealed that all indicators total contents of heavy metals in the years of fertilization and subsequent years were below the MPL. Application of lime also had no significant increase in the concentrations of heavy metals. It is established that the use of non-conventional fertilizers of different nature, ecologically reasonable doses, no significant prolonged action on the properties of the arable horizon of gray forest soils. The results indicate the possibility of soil utilization as fertilizer, sewage sludge and dolomite dust in the organization biogeochemical monitoring of heavy metals in the soil in the production of environmentally safe products.
