1. Adding ammonium bicarbonate method to stacking manure: cut the crop stalk into pieces, add 0.5-1% ammonium bicarbonate and appropriate amount of human excrement for stacking, cover with mud and seal, and become a good bio-potassium fertilizer after decomposing.
2, fresh cow dung added soy milk pulp method: add 1.25 kg of soy milk per 50 kg of fresh cow dung, artificially stirred evenly, sealed at 25 ° C for 3-6 days, 3 times with water for top dressing, its fertilizer efficiency than ammonia Still high.

4, human feces and urine added gypsum powder method: add 5 kg of gypsum powder in every 50 kg of human excrement, add 25 kg of water, mix and mix evenly, cover and store for 10 days, can reduce the loss of nitrogen volatilization, increase fertilizer efficiency .
5. Adding ferrous sulfate to human excrement: Adding 300 g of ferrous sulfate (green strontium) to every 50 kg of human excrement can convert ammonium carbonate in urine into stable ammonium sulfate.
6. Adding superphosphate to human excrement: Add 2.5 kg of superphosphate in every 50 kg of human excrement, mix it evenly and store it for 5-7 days, not only to prevent nitrogen loss, but also greatly improve fertilizer utilization. .
