Five kinds of simple farm soil fertilizer production method

Soil nitrogen and phosphorus fertilizers: processed into bone meal using animal bones. Its high proportion of nitrogen and phosphorus is the best base fertilizer for plants, which is equivalent to high-efficiency nitrogen-phosphorus compound fertilizer. Methods: The raw bones were steamed to remove some of the fat and then crushed to fine powder, which contained 2% to 6% of nitrogen and 15% to 28% of phosphorus pentoxide. Potassium dihydrogen phosphate: Take the ratio of superphosphate and hot water in the ratio of 2:5, stir and set it for 48 hours, and filter it for backup; take the ratio of 6:15 of the straw ash and hot water and let it stand for 10 minutes. After filtration, it will The two solutions were mixed to prepare a 1% potassium dihydrogen phosphate crude solution. Soil ammonia water: 50 kg of fresh cow dung, 50 g of soya bean powder, and 5 kg of cooked plaster, sealed at 25 °C for 3 days, with 3 times the water application, fertilizer efficiency higher than ammonia. Soil ammonium sulfate: Use 50 kg of human urine, 5 kg of plaster offal, and 25 kg of water to mix well. After sealing for 10 days, use it equivalent to ammonium sulfate. Soil Compound Fertilizer: Stir 100 g of superphosphate powder and 120 to 150 kg of urine water, make it into a cone, externally seal it with 3 cm thick mud, and simmer it for 7 days. It can be used as base fertilizer and top dressing. Fertilizer use. Fertilizers should not touch the seeds and roots of plants, and should be covered with soil. The above-mentioned 5 kinds of self-made farmland fertilizers are widely used, they are simple in raw materials, economical and practical, reduce costs, and reduce pollution and pollution. The effect can be comparable to that of chemical fertilizers. The majority of farmers can try it, make materials locally, and make their own fertilizers. To lay a solid foundation for the harvest of crops and Chinese herbal medicines.
