What methods are there to improve the effectiveness of farmyard manure? Please provide an introduction to the efficiency-enhancing methods.
To improve the efficiency of farmyard manure, you can refer to the following methods:
1. Add fine dry soil, turf, and other highly absorbent materials to human excrement and urine. Human excrement and urine have high nutrient content, decompose quickly, and act fast, but are prone to loss. If materials with strong absorption capacity such as dry soil and turf are placed in the manure pit as a cover or mixed into the excrement and urine to absorb urine and ammonia gas, nitrogen loss can be greatly reduced. According to experiments, adding 25% fine dry soil to human excrement and urine can reduce nitrogen loss by 10%.
2. Add superphosphate to human excrement and urine. Adding 3%-5% superphosphate to human excrement and urine can not only reduce nitrogen loss, but also increase nutrients such as phosphorus in human excrement and urine.
3. Add ferrous sulfate to human excrement and urine. Add 250-300 grams of ferrous sulfate per 50 kg of human excrement and urine, which both preserves nitrogen and prevents odor.
4. Add gypsum powder to human excrement and urine. Add 5 kg of calcined gypsum powder and 25 kg of water per 50 kg of human excrement and urine, mix evenly, seal for 10 days, and then apply.
5. Add soybean flour to fresh cow manure. Add 50 grams of soybean flour per 50 kg of fresh cow manure, place it in a vat and stir evenly, seal at 25°C for 3-5 days, and dilute with 3 times the amount of water when applying.
6. Add superphosphate to barnyard manure. Add 2% superphosphate to barnyard manure, stir evenly, and store in a pile for about 20 days; its fertilizer efficiency can be increased by more than 1 time.
7. Mixing and composting farmyard manure with phosphate fertilizer can also improve phosphate fertilizer efficiency. This is because the carbon dioxide and organic acids produced during the decomposition of farmyard manure help the conversion of insoluble phosphorus compounds in phosphate fertilizer. At the same time, the humic acid in farmyard manure has strong adsorption and exchange capacity and can combine with metal ions such as iron, aluminum, and calcium that play a "fixing" role in the soil to form complexes, thereby activating and protecting phosphorus and improving utilization. According to research, applying phosphate fertilizer mixed and composted with organic fertilizer can increase phosphate fertilizer utilization by 10%-30%; among this, composting phosphate rock powder mixed with stable manure for 30 days can increase weakly acid-soluble phosphorus by 67.6%. When phosphate fertilizer is mixed and composted with organic fertilizer, the proportion of superphosphate added is generally 2%-3%, calcium magnesium phosphate fertilizer is about 5%, and phosphate rock powder is 5%-10%.
