The method for preparing biogas humic acid fertilizer is to stack the biogas residue taken out from the biogas tank together with organic garbage or soil, and add a layer of 20-30 cm thick biogas residue to a layer of garbage (or soil). A large round table-shaped fertilizer pile, then cover the surface with some mud and shoot it, stacking for 15-20 days to become biogas and fat. If 20-25 kg of calcium, magnesium, phosphate or phosphate rock is added to each cubic meter of biogas residue during stacking, it will become a bio-fermented phosphate fertilizer. The fertilizer is suitable for use as a base fertilizer, and the application amount per acre is 1000 kg.
According to the experiment of the Beijing Academy of Agricultural Sciences, the biogas rot phosphate fertilizer has a significant effect on increasing yield of wheat, corn, eggplant, green pepper, etc., corn can increase yield by 13.8%, and green pepper can increase yield by 15%.
