METHOD OF BIOTECHNOLOGICAL PROCESSING OF DROPPINGS IN POULTRY FARMING

摘要

FIELD: biotechnology.;SUBSTANCE: invention relates to biotechnology and can be used in processing of fresh chicken droppings. Method involves mixing of bird droppings with moisture-absorbing materials and composting stimulator based on microorganisms and its introduction into substrate. Composting is carried out at temperature of ambient medium and active aeration for 5–7 days. Wherein composting stimulator is consortium of soil microorganisms Trichoderma viridae, Azotobacter chroococcum, Azomonas agilis 1:1:2 with concentration of Azotobacter chroococcum – 2×10⁵ CFU/ml, Azomonas agilis – 4.3×10⁵ CFU/ml, Trichoderma viride – 1.5×10⁴ CFU/ml. As water-absorbing material sawn off hardwood is used in amount, providing specified moisture content of compost mixture, and composting stimulator is introduced into substrate in form of mixture of excrements and sawdust or wood chips in ratio of 1:2.;EFFECT: invention makes it possible to restore soil fertility, reducing environmental contamination in area of poultry enterprise.;1 cl, 3 tbl
