Calcium phosphate is added to human excrement. Add 5 kg of superphosphate per 100 kg of human excrement, stir evenly, and store for 5 to 10 days. The chemical reaction can convert the volatile ammonium carbonate in human excrement into a stable ammonium phosphate to prevent the loss of nitrogen volatilization. At the same time, the phosphorus in human excrement is increased, the quality of the fertilizer is improved, and nitrogen is preserved.
Add salt to human waste. For every 100 kilograms of human excrement, in addition to adding 5 kg of superphosphate, adding 3 kg of salt and stirring for 10 days, the nitrogen content can be greatly increased, and the water is watered 3 times when used.
Add ferrous sulfate (green sputum) to human excrement. By adding 500-600 g of ferrous sulfate per 100 kg of human excrement, the ammonium carbonate in human excrement can be converted into ammonium sulfate with stable properties, thereby preventing fertilizer, deodorizing and preventing the loss of nitrogen volatilization.
Add soy milk in fresh cow dung. Add 2.5 kg of soy milk per 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 is necessary to use 3 times of water for topdressing.
Add calcium phosphate to manure and compost. Adding 20% ​​superphosphate to manure and compost, stacking for 20 to 25 days, can not only accelerate the composting process of compost and manure, but also increase the effective phosphorus content and improve the quality of manure and compost.
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.
How to effectively improve the efficiency of farmyard fertilizer
The scientific method of accumulating farmyard manure can effectively prevent the volatilization loss of fertilizer efficiency, help the absorption of phosphorus, and double the fertilizer efficiency. The method is: when stacking fertilizer, mix 5-10 kg of superphosphate per 100 kg of compost, and after 10-20 days of stacking, the phosphorus content can be increased.
