Fertilizer production sites should be flat and near the water leeward sunny place, can be produced in the open air all year round. Fertilizer materials (take one ton of dry stalks as an example) to produce 1,000 kg of stalks, 20 kg of cake flour (eg, peanut cakes, bean cakes, cotton cakes, rapeseed cakes, etc.), and “Kent Green†No. 2 Inoculated with 1 kg of bacteria. The crop stalk (such as corn stalk) is crushed with a pulverizer or cut with a rake. The length is usually 1-3 cm. The smashed and cut straw is wetted and infiltrated with water. The water content of the straw is generally controlled at about 70%. Mix 20 kg of cake flour with 1 kg of bacteria, and spread the cake flour on the surface of the straw that has been poured by water. With a shovel and other tools overturned again, lined into a width of 2 meters, 1.5 meters high length of the bar, covered with plastic cloth can be. Straw rot is warmed up and it takes only 1 day from room temperature to 50°C. High temperature: Generally only 2 days from 50-70°C. Cooling: From high temperature to below 50°C, generally about 10 days, three phases. When the straw becomes brown or dark brown, the wet leaves are soft and elastic by hand. When dry, it is brittle and breaks easily. When the pile collapses by 1/3 or 1/2 when it is piled, it indicates that the fertilizer has matured.

It also contains a variety of trace elements, which are common fertilizers suitable for various crops and various soils, and have a significant effect of improving product quality and increasing yield.
