Add superphosphate in human fecal urine Add 5 kg superphosphate per 100 kg of human excreta, mix well and store for 5 to 10 days. The chemical reaction can make ammonium carbonate, which is easily used in human excrement and urine, be converted into stable ammonium phosphate, thereby preventing the loss of nitrogen volatilization, increasing phosphorus in human excrement and improving the quality of fertilizer. In human excrement, add salt to every 100 kilograms of human excrement, add 5 kg of superphosphate and 3 kg of salt, stir and evenly ferment for 10 days, and increase the nitrogen content. When used, water 3 times. In fresh cow dung, add yellow soybean milk, add 2.5 kg of soybean milk per 100 kg of fresh cow dung, stir in a cylinder, and seal at a temperature of 25°C for 3 to 6 days. When you use it, you need to dilute water 3 times to make top dressing. Adding calcium superphosphate to manure and compost Adding 20% ​​of superphosphate to the compost and manure and stirring evenly and stacking it for 20 to 25 days can prevent the loss of nitrogen in the manure, accelerate the decomposed process of the compost and increase the available phosphorus. Content, improve manure, compost quality. Calcium superphosphate mixed with grass ash To pulverize 1 kg of superphosphate, add 2.5 kg of water and stir it to make it precipitate naturally. Another 3 kg of grass ash plus 5 kg of water soaked for a period of time. Finally, the two leach liquors were filtered and mixed to make potassium dihydrogen phosphate equivalent to 1 acre field. Potassium carbonate production by soil method The ash of the plant is soaked in water for about 5 minutes, stirred well, and then filtered with white gauze. The dark yellow liquid that is filtered off is the liquid potassium carbonate fertilizer with the concentration of about 2%. The use of a concentration of 0.5%, that is to take 1 kg of liquid potassium carbonate mixed with 4 kg of foliar spray, can also be used as base fertilizer, seed fertilizer.
