1. Adding ferrous sulfate (green sputum) to human waste
The addition of 0.5 kg of ferrous sulfate per 100 kg of human excrement can convert ammonium carbonate in human excrement into stable ammonium sulfate, thereby functioning to protect fertilizer, deodorize and prevent nitrogen volatilization.
Second, human excrement plus superphosphate
Add 5 kg of superphosphate in 100 kg of human excrement, mix and store for 5 to 10 days, which can convert the highly volatile ammonium carbonate in human excrement into stable ammonium phosphate, which can improve nitrogen and improve nitrogen. The purpose of fertilizer quality.
Third, the addition of superphosphate to the ash
3 kg of fresh grass ash, soaked in 15 kg of water for 2 to 4 hours, then add 1 kg of superphosphate and mix well. After 6 hours, add 50 kg of water to stir. After sedimentation, take the clear liquid spray to obtain dihydrogen phosphate. Potassium has the same effect.
4. Adding ammonium bicarbonate to the heap fertilizer
Cut the crop stalk into 5~10 cm short sections, add 1% ammonium bicarbonate, which is the total weight of the stem, add a proper amount of human excrement, and then cover it with mud. After decomposing, it becomes a highly efficient organism. Potash fertilizer.
5. Adding superphosphate to manure
100 kg of manure, adding 20 kg of superphosphate to stir evenly, after stacking for 20 days, not only can prevent the volatilization of nitrogen in the manure, but also accelerate the decomposing process of manure, increase the content of available phosphorus, and improve the fertilizer efficiency of manure.
