FIELD: agriculture. SUBSTANCE: the present innovation deals with processing poultry dung to obtain fertilizer. One should dissolve raw poultry dung up to the moisture of not less than 94% followed by mechanic filtration. Dissolving should be carried out by applying mother liquor of bischofite natural mineral of sulfate type of MgCl2.6H2O formula at the density of 1.1-1.5 t/cu. m for 3-6 min, bischofite expenses correspond to 30-70 weight% against dry dung. The innovation in question enables to increase efficiency of fertilizer due to enrichment by microelements. EFFECT: higher efficiency of dehydration. 7 tbl |
