Farmers have low levels of active ingredients and slow fertilizer effects. Adding a little “additives†to farmyard fertilizers can not only prevent the loss of volatile components, but also increase fertilizer efficiency.
Human fecal urine is added with ferrous sulfate in 500 to 600 grams of ferrous sulfate per 100 kg of human excrement, which allows ammonium carbonate in human excrement to be converted into stable ammonium sulfate, which acts as a nutrient and deodorant to prevent nitrogen. The role of volatilization.
Calcium superphosphate in human excreta Add 5 kg of superphosphate to 100 kg of human excreta, mix it well, store it for 3 to 10 days, and convert the highly volatile ammonium carbonate in human excrement into stable ammonium phosphate. , Increase the phosphorus content of human waste, and keep nitrogen with phosphorus.
Add Calcium Sulfate to Plant ash. Soak 3 kg of plant ash to 15 kg of water, add 1 kg of superphosphate, mix well, add 50 kg of water after 6 hours, mix well, and take clear solution after standing to settle. Potassium dihydrogen phosphate has the same fertilizer effect.
Stacked manure by adding ammonium bicarbonate will plant stalks, leaves cut into pieces, adding 0.5% to 1% of ammonium bicarbonate and the amount of manure urine stack, and then covered with mud seals decomposed into a potent bio-potash fertilizer.
The addition of superphosphate to manure by adding 20% ​​of superphosphate to the manure and mixing it for 20 days will not only prevent the loss of nitrogen nutrient in manure, but also accelerate the decomposed process of manure and increase the available phosphorus content.
Fresh cow dung soy milk added 2.50 kilograms of yellow soybean milk per 100 kilograms of fresh cow dung. Stir in the jar and place it in a sealed place for 3 to 6 days. The water should be top-dressed 3 times, and its fertilizer efficiency is better than ammonia.
