摘要：
FIELD: agriculture.SUBSTANCE: invention relates to agriculture, and in particular to methods for protecting horizontal drainage from insoluble precipitate formation. To protect the horizontal drainage from insoluble precipitate formation in the cavity of the drain, exhaust gases of the internal combustion engine. New is that simultaneously with the supply of exhaust gases to the cavity of the drain, a fine powder of coal and/or brown coal from thermal power plants is supplied, containing not less than 28 mg/kg of copper. Powder of coal and/or lignite ash of thermal power stations together with the flow of exhaust gases enters the inner surface of drainage pipes and in the cracks of drainage pipes. Copper and calcium carbonate, which are contained in the ashes, block the bacterial process of converting iron compounds into insoluble forms. Iron bacteria die. Process of insoluble precipitate formation stops.EFFECT: invention compared with similar solutions provides a 42 % reduction in the intensity of drainage
