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.

Direct effect and aftereffect of sapropel on agricultural crops yield and agrochemical properties of light grey forest soil

“…Laboratory analysis of the content of heavy metals in soil and potato tubers showed approximately the same low content in all variants. It is also confirmed by studies carried out under the land monitoring program, confirming the ecological purity of the territory of the Chuvash Republic [7,8].…”

“…Numerous results of scientific research on the cultivation of agricultural crops using only organic fertilizers (semi-rotted manure, compost, peat), urban wastewater sludge, as well as by-products of the food industry and waste processing (liquid and solid products of a biogas plant, horn-hoofed shavings, bone meal, cake, etc.) showed their high economic efficiency [1], [2], [3], [4], [5], [6], [8], [9], [12], [ 19], [20], [21]. The research carried out in greenhouses showed that by-products of industrial production, i.e., products of a biogas plant, municipal wastewater sludge, etc.…”
