How to use farmyard manure to improve its fertilizer efficiency

Although farmyard manure has advantages such as rich nutrient content and loosening the soil, it also has disadvantages such as low effective content and slow fertilizer effect. How can we enhance the fertilizer efficiency of farmyard manure by maximizing its strengths and avoiding its weaknesses? Practice has proven that mixing an appropriate amount of chemical fertilizer into farmyard manure can not only effectively prevent the volatilization and loss of fertilizer efficiency, but also double the fertilizer effect.

Adding ferrous sulfate to human excrement and urine

Adding 500-600 grams of ferrous sulfate to every 100 kg of human excrement and urine can convert the ammonium carbonate in the excrement and urine into the more stable ammonium sulfate, thereby effectively inhibiting nitrogen loss in human excrement and urine.

Adding superphosphate to human excrement and urine

Adding 5 kg of superphosphate to 100 kg of human excrement and urine, stirring evenly and then storing for 3-5 days, can convert the highly volatile ammonium sulfate in the excrement and urine into the stable ammonium phosphate, using phosphorus to preserve nitrogen.

Adding superphosphate to barn manure

Adding superphosphate at 2% of its weight to barn manure, stirring thoroughly and evenly, then stacking and storing for about 20 days, produces a high-quality organic fertilizer with fertilizer efficiency increased by more than 1 times.

Adding ammonium bicarbonate to composted manure

After mixing crushed plant stalks and other raw materials with soil (or the bottom of a firewood or straw stack), add 1% ammonium bicarbonate and mix well, pile it up, seal the pile with mud for composting, and after decomposition it becomes a high-quality and high-efficiency biological potassium fertilizer.

Adding superphosphate to plant ash

Soak 3 kg of plant ash in 15 kg of water, then add 1 kg of superphosphate, stir evenly, add 50 kg of water after 6 hours and mix well, and after it settles, take the clear liquid and spray it to obtain the same fertilizer effect as potassium dihydrogen phosphate solution.
