Prospects for the use of poultry and drilling waste in agriculture

The article presents the possibilities of obtaining useful products from poultry and oil industry wastes using Mephosphon biologically active agent. The use of an aqueous solution of the Mephosphone preparation in ultra-low concentrations (10−6 –10−8 %) allowed obtaining the Compost UP-1 product from chicken manure and the Meliorant product from drilling waste. The Compost UP-1 belongs to the 4th hazard class in terms of physico-chemical and sanitary-biological characteristics, and the Meliorant product in terms of pollutant content belongs to the 5th hazard class. Studies on the influence of useful products derived from waste were carried out in the field in the experimental fields of the Laishevsky district of the Republic of Tatarstan. The Compost UP-1 and Meliorant products were introduced during pre-sowing cultivation in an amount of 26 t/ha and 1.3 t/ha, respectively. For comparison, during the research, reference plots were organized (Reference). The seeds were spring wheat of the Yoldyz variety (Compost UP-1) and Idelle (Meliorant). The analysis of growth and productivity indicators of plants grown in different areas showed that the use of the obtained products improved soil fertility: the introduction of the Meliorant product optimizes soil pH, activates mass transfer processes, and the introduction of the Compost UP-1 product increases the content of nutrients (N, P, K). So at the tillering stage in the section with Compost UP-1, the average phytomass per unit length of plants was 1.8 times higher than in the Reference. The use of Compost UP-1 leads to a significant improvement in grain quality: the mass fraction of protein increased by 32 %, vitreous content by 60 %, and the content of crude gluten by 34 %. Productivity increased and amounted to 42 kg/ha, which is 14 kg more than in the Reference. The use of the Meliorant also activated the growth of plants, and led to an improvement in the quality of grain.
