EFFICIENCY OF APPLICATION OF SOLID PRODUCTS OF BIOGAS INSTALLATION ON OIL-POLLUTED SOILS

Abstract

The article contains the results of scientific research on the use of solid products from the processing of poultry manure in a biogas plant of OOO NPO Agrobiogaz, St. Petersburg (hereinafter referred to as TBU or solid bio-fertilizer) on soils contaminated with oil products. Solid biogas plant processing products are a non-traditional type of organic fertilizer. The chemical composition of biofertilizer was determined: 1 ton of a natural substance contains on average 16,5 kg/ton of total nitrogen, 20 kg/ton of total phosphorus and about 16 kg/ton of total potassium, as well as trace elements. Scientific studies have shown that the use of bio-fertilizer on artificially polluted soils weakens their toxic effect, and with an increase in the dose of bio-fertilizers, it consistently increases the yield of barley. The results of scientific studies have shown that solid products of a biogas plant can be effectively used as improver on oil-polluted soils.
