Quick-acting compound fertilizer with five key nutrients: Start by mixing plant ash and soft water (such as river or pond water) in a 1:10 ratio. Place the mixture in a pot and boil it, then Filter out any impurities to create an alkaline solution. Next, combine bovine bone powder with soft water in a 1:7 ratio, boil again, and remove the residue. Mix this with water in a 1:3 ratio to form a saline solution. Meanwhile, heat plaster in a stove until it becomes powder for later use. In a separate pot, first add 30% of the alkaline solution, bring it to a boil, and then gradually stir in 13% bovine bone extract, 2% saline solution, and 30% gypsum powder. Continue boiling for another 10 to 15 minutes. After that, add quicklime (you can spread it on a cement floor to make it fine) into the mixture. This process produces 23 kilograms of five-in-one compound fertilizer from 50 kilograms of raw materials, containing 28% nitrogen, 0.5% iodine, and 30% potassium. It can be used as both base fertilizer and top dressing, making it a versatile option for various crops. To prepare ammonium phosphate quick-acting compound fertilizer, start by placing 5 kilograms of manure in a large iron pan. Add 0.2% to 0.5% of acid—such as sulfuric or nitric acid—to help soak and ferment the material. Let it sit for about 4 to 5 hours. Then mix in 5 kilograms of human urine and 10 kilograms of chicken and sheep manure, and pour everything into a pot. Add 3 kilograms of superphosphate to the mixture. Heat the pot over fire while continuously stirring with a wooden stick to ensure even cooking. Once cooked, let it dry. The resulting ammonium phosphate compound fertilizer is rich in nitrogen and ideal for topdressing crops, especially during their growing season. This method not only improves soil fertility but also enhances plant growth effectively.
