What problems should be paid attention to when composting organic fertilizer?

1. Requirements for fermentation raw materials: fermentation raw materials (such as feces and other agricultural wastes) should be fresh without natural composting. 2. Requirements for auxiliary materials: the water content of fermentation auxiliary materials (such as straw, rice bran, etc.) should be moderate, the water absorption is strong, the particle or length is appropriate, and it should not be too large. The addition amount should be determined according to the water content of fermentation raw materials. 3. Strain should be removed evenly: it needs at least 50 grams for one ton of raw materials to be fermented by organic fertilizer fermentation strain. Considering that it is impossible to remove the strain evenly on the fermentation materials, when using it, first mix 50 g of strain into 500 g of wheat bran, sawdust, oil, rice bran and other raw materials, and then remove them into the fermentation materials, and then mix them evenly and stack them for fermentation....
