5 methods to improve the efficiency of farmyard manure

1. Add ferrous sulfate (green sputum) to human excrement: Add 500-600 g of ferrous sulfate per 100 kg of human excrement, which can convert ammonium carbonate in human excrement into stable ammonium sulfate. To protect the fertilizer from deodorization and prevent the loss of nitrogen volatilization.

2. Add soy milk in fresh cow dung: Add 2.5 kg of soy milk to 100 kg of fresh cow dung, mix well in the tank, and seal for 3-6 days at 25 Â°C. Its fertilizer efficiency is higher than the equivalent amount of ammonia. When applying, it needs to be watered 3 times for topdressing.

3. Add calcium phosphate in manure and compost: add 20% superphosphate in compost and manure and mix well. Stacking for 20-25 days can prevent the loss of nitrogen in the manure and accelerate the process of composting of manure compost. Increase the effective phosphorus content and improve the quality of manure and compost.

4, superphosphate mixed with plant ash: 1 kg of superphosphate pulverized, add 2.5 kg of water and stir evenly, let it naturally precipitate. In addition, 3 kg of grass ash and 5 kg of water were soaked for a period of time. Finally, the two leaching leaves are filtered and mixed to form a potassium dihydrogen phosphate equivalent to spraying 1 mu of field. Spray 50 kg with water when using.

5. Soil-based production of potassium carbonate: soak the ash in water for about 5 minutes, stir evenly, and then filter it with white gauze. The dark yellow liquid filtered is liquid potassium carbonate fertilizer with a concentration of about 2%. The concentration is 0.5%, that is, 1 kg of liquid potassium carbonate and 4 kg of water are used for foliar spraying, and it can also be used as base fertilizer and seed fertilizer.
