Add calcium superphosphate to human waste. Add 5 kg superphosphate per 100 kilograms of human waste, mix well, store for 5-10 days. The chemical reaction can make the volatile ammonium carbonate in human waste and urine be converted into ammonium phosphate with consolidating properties, avoid the loss of nitrogen volatilization, increase the phosphorus content in human waste, and improve the quality of fertilizer. nitrogen.

Add salt to human waste. For every 100 kilograms of human excrement, in addition to adding 5 kilograms of superphosphate, 3 kilograms of additional salt is added. After fully stirred for 10 days, the nitrogen content can be greatly increased, and when used, it can be watered 3 times.

Add yellow soybean milk in fresh cow dung. Add 2.5 kg of soy milk per 100 kg of fresh cow dung. Stir in the cylinder and seal it at 25°C for 3-6 days. The fertilizer efficiency will be greatly improved. When the application is required to dilute 3 times for topdressing.

Add calcium phosphate to manure and compost. Adding 20% ​​of superphosphate to manure and compost for 20-25 days will not only accelerate the composting process of composting and composting, but also increase the available phosphorus content and improve the quality of manure and compost.

Superphosphate with grass ash. After crushed 1 kilogram of superphosphate, add 2.5 kilograms of water and stir it to make it accumulate naturally. In addition, 3 kg of ash and 5 kg of water are soaked for a period of time. Finally, the two leach liquors were filtered and mixed to become potassium dihydrogen phosphate similar to spray application. When used, 50 kilograms of water was sprayed.
