Add calcium superphosphate to human excreta Add 5 kg of superphosphate per 100 kg of human excrement, stir evenly, and store for 5 to 10 days. Through chemical reaction, the volatile ammonium carbonate in human excrement can be converted into stable ammonium phosphate to prevent the loss of nitrogen volatilization. At the same time, the phosphorus element in human excrement is increased, and the nitrogen is supplemented with phosphorus to improve the quality of the fertilizer.
Adding salt to human excrement In every 100 kilograms of human excrement, in addition to adding 5 kg of superphosphate, adding 3 kg of salt, fully stirred and fermented for 10 days, can greatly increase the nitrogen content. It can be watered 3 times with water when using.
Add soy milk in fresh cow dung Add 2.5 kg of soy milk to 100 kg of fresh cow dung. Stir in the tank and seal it for 3 to 6 days at 25 °C. The fertilizer efficiency will be greatly improved. When applying, it needs to be watered 3 times for topdressing.
Adding superphosphate in manure and compost, adding 20% ​​superphosphate to manure and compost, stacking for 20 to 25 days, not only accelerates the composting process of compost and manure, but also increases the effective phosphorus content and improves manure and compost. quality.
Superphosphate with grass ash After pulverizing 1 kg of superphosphate, add 2.5 kg of water and mix well to allow it to precipitate naturally. In addition, 3 kg of grass ash and 5 kg of water were soaked for a period of time. Finally, the two kinds of leachate were filtered and mixed to become potassium dihydrogen phosphate similar to spray application, and 50 kg of water was sprayed when used.
