Fresh animal manure (cow manure, chicken manure, pig manure) (excluding other impurities), supplemented with appropriate proportion of supplementary materials (straw, bran, etc.) (adjusting the moisture content of the stockpile, C_N), is generally controlled at 25-30% of the input weight of the manure. The amount of detonator added is implanted into one kilogram of starter per three tons of animal manure. Some materials are evenly mixed with forklift trucks and stacked in strips (about 50% - 60% moisture content), with a width of 2.8 - 3.0 meters and a height of 1.2 - 1.4 meters.
