Human fecal urine with ferrous sulfate Add 500-600 grams of ferrous sulfate per 100 kilograms of human fecal urine, can make ammonium carbonate in human excrement into stable ammonium sulfate, play a role in protecting fertilizer and deodorizing, preventing nitrogen from losing volatilization. Human urine and superphosphate Add 5 kg superphosphate per 100 kilograms of human waste. Stir and store for 3 to 10 days. This can convert ammonium carbonate, which is highly volatile in human waste, into stable ammonium phosphate, thereby increasing human waste. Phosphorus element, phosphorus nitrogen, fertilizer effect greatly increased. Plant ash and superphosphate With plant ash 6 kg watered 30 kg soaked, plus 2 kg of superphosphate, 6 hours and then add 100 kg of water and mix well, after standing and taking the liquid spray, you can get the same fertilizer effect as potassium dihydrogen phosphate. Stacked manure and ammonium bicarbonate The weeds, plant stems, and leaves were cut into pieces, and 0.5% to 1% of ammonium bicarbonate was added and the human waste was piled up and tanned. Then, the mud was covered and sealed, and when fully cooked, it became a highly efficient biopotash fertilizer. Circulation with superphosphate 20% of superphosphate is added to the feces taken out of the livestock circle and mixed well. After 20 days of storage, not only the loss of nitrogen nutrient in the ring fertilizer can be prevented, but also the decomposition of the circle fertilizer can be accelerated and the content of available phosphorus can be increased.
