How to Improve Farm Fertilizer Efficiency
1. Adding ammonium bicarbonate method for stacking manure: The crop stems are cut into pieces, 0.5-1% of ammonium bicarbonate is added, and the amount of human feces and urine is used for stacking. The mud is covered and sealed, and after decomposed, it becomes a good biopotash fertilizer. 2. Adding soybean milk to fresh cow dung: Add 1.25 kg of soy milk per 50 kg of fresh cow dung, mix it evenly, seal for 3-6 days at an air temperature of 25°C, and dilute the water 3 times as top dressing. The effect of fertilizer is better than ammonia. Also high, 3, plant ash added superphosphate method: every 6 kilograms of plant ash plus 10 kilograms of water, soaked for 6 hours after the filter to take the liquid to be used; another take 2 kilograms of superphosphate powder, add water, stir evenly, let the natural precipitate after taking Filtrate, and then the two solutions were mixed, watered 100 kg spray to obtain the same fertilizer effect as potassium dihydrogen phosphate. 4. Add gypsum powder method to human waste: Add 5 kg of cooked gypsum powder per 50 kg of human waste, add 25 kg of water to mix evenly, cover and preserve for 10 days, reduce nitrogen evaporation loss and increase fertilizer efficiency. . 5. Add human urine ferrous sulfate method: 300 grams of ferrous sulfate (green hydrazine) is added to every 50 kilograms of human waste, and ammonium carbonate in urine can be converted into stable ammonium sulfate. 6, human fecal urine added superphosphate method: In every 50 kilograms of human excrement, add 2.5 kilograms of superphosphate, stir and store for 5-7 days after use, not only to prevent the loss of nitrogen, but also greatly improve the fertilizer utilization .
