Additives to increase farmyard manure
The content of active ingredients in farmyard manure is low, and the fertilizer efficiency is slow. If a little “additive†is added to the farmer's fertilizer, it can not only prevent the loss of the active ingredient, but also increase the fertilizer efficiency.
The addition of ferrous sulfate to human urine in the urine of 500-600 grams of ferrous sulfate per 100 kg of human urine, can convert human urine ammonium carbonate into a stable nature of ammonium sulfate, to prevent fertilizer and deodorize, prevent nitrogen volatilization The role.
Adding superphosphate to human excrement and adding 5 kg of superphosphate in 100 kg of human excrement, stirring and storing for 3-10 days, can convert the highly volatile ammonium phosphate in human excrement into stable ammonium phosphate. Increase the phosphorus content of human excrement and phosphorus to protect nitrogen.
Add calcium superphosphate to the ash, add 3 kg of grass ash to 15 kg of water, then add 1 kg of calcium phosphate, stir evenly. Add 6 kg of water and mix evenly after 6 hours. After standing and sedimenting, take the liquid spray to obtain Potassium dihydrogen phosphate is similar in fertilizer efficiency.
Adding ammonium bicarbonate to the manure fertilizer to cut the stalks and leaves of the plant into pieces, adding 0.5%-1% ammonium bicarbonate and a proper amount of human excrement, and then sealing with mud to form a high-efficiency organic fertilizer after decomposing.
Adding superphosphate to the manure and adding 20% ​​superphosphate to the manure, stirring evenly, after stacking for 20 days, not only can prevent the loss of nitrogen nutrients in the manure, but also accelerate the decomposing process of manure and increase the effective phosphorus content.
Add fresh soy milk to the fresh cow dung, add 2.5 kg of soy milk per 100 kg of fresh cow dung, stir evenly into the jar, seal for 3-6 days, apply water 3 times with top dressing, and its fertilizer efficiency is better than ammonia.
