METHOD TO RECYCLE EMISSIONS OF HAZARDOUS ADMIXTURES IN AIR OF STOCK-RAISING PREMISES Russian patent published in 2012 - IPC A01G7/02 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture. The method consists in additional fertilising of plants with carbonic acid gas and nitric fertilisers due to supply of air with a mixture of gases along pipelines from a stock-raising room into a system of aeration drainage of a soil layer of greenhouses. In periods between crop combinations these emissions are supplied to sites for preparation of substrates from organic materials, volume of which is determined using the following formula: where W - volume of composted organic material, m³; 24 - number of hours per day; - quantity of ammonium discharged from a stock-raising room, kg/hr/head; T_com - period of composting, days; K₁ - content of nitrogen in ammonium, %; N - number of animal heads in a stock-raising room; G_fert - quantity of nitric fertilisers, which are to be introduced in composting of organic materials, kg/m³; K₂ - nitrogen content in a fertiliser used for composting, %.

EFFECT: invention makes it possible to increase environmental compatibility of a stock-raising complex.
