EFFECT OF PIG FARM WASTEWATER AND BIOPREPARATIONS ON THE PROPERTIES OF TYPICAL CHERNOZEM
The questions of application of pig farm wastewater and their impact on the properties of typical chernozem have been considered. The positive effect of wastewater and biopreparations on soil fertility has been noted. The content of mobile forms of phosphorus and exchange potassium was increasing, and the hydrolytic acidity of the soil was decreasing. The combined application of wastewater and biopreparations was reducing the content of heavy metals in the soil.
