How to improve the use effect of farm manure

Although farm manure has the advantages of rich nutrient content and loose soil, it also has some disadvantages such as low effective content and slow fertilizer effect. How can we make full use of our strengths and avoid weaknesses to improve the efficiency of farm manure? Practice has proved that the appropriate amount of mixed chemical fertilizer in farm manure can not only effectively prevent the volatilization and loss of fertilizer efficiency, but also double the fertilizer efficiency.

Adding ferrous sulfate to human feces and urine

The addition of 500 grams of ferrous sulfate per 100 kg of human feces and urine can convert ammonium carbonate in human feces and urine into ammonium sulfate with stable properties, thus effectively inhibiting the loss of nitrogen in human feces and urine.

Adding superphosphate to human feces and urine

Adding 5 kg calcium superphosphate to 100 kg human feces and urine, stirring evenly and then spreading and storing for 3 to 5 days, the easily volatile ammonium sulfate in human feces and urine can be converted into stable ammonium phosphate and nitrogen can be preserved by phosphorus.

Adding calcium superphosphate to ring fertilizer

Add 2% calcium superphosphate by weight to the ring fertilizer, mix it well and store it for about 20 days, then become a high-quality organic fertilizer, and the fertilizer efficiency can be more than doubled.

Add bicarbonate to compost

After mixing raw materials such as crushed plant straw with soil (or firewood and grass stack bottom), add 1% ammonium bicarbonate to mix well, pile it into a pile, seal and compost with mud, and become a high-quality and efficient biological potash fertilizer after ripening.

Adding calcium superphosphate to plant ash

Soak 3 kg of plant ash in 15 kg of water, add 1 kg of superphosphate, stir evenly, add 50 kg of water 6 hours later, and spray the clear liquid after it is still precipitated, the same fertilizer effect as potassium dihydrogen phosphate can be obtained.
