Earth-based quick-release compound fertilizer, a two-in-one and five-in-one formula, is made by combining plant ash with soft water (such as river or pond water) in a 1:10 ratio. The mixture is boiled in a pot, then filtered to remove impurities, resulting in an alkaline solution. Next, bovine bone powder is mixed with soft water at a 1:7 ratio and boiled again, with the liquid filtered out. This is then combined with salt water at a 1:3 ratio to create a saline solution. Gypsum is heated in a stove until it turns into powder for later use. Afterward, 30% of the alkaline solution is placed in a pot and brought to a boil. Then, 13% of the bovine bone solution, 2% of the salt solution, and 30% of the gypsum powder are added together while stirring continuously. After boiling for another 10 to 15 minutes, quicklime is introduced into the mixture. The quicklime can be spread on a cement floor and ground into fine powder before being added. Using this method, 50 kg of raw materials can produce 23 kg of five-in-one compound fertilizer containing 28% nitrogen, 0.5% iodine, and 30% potassium, suitable as both base fertilizer and top dressing. For the preparation of ammonium phosphate quick-acting compound fertilizer, start by placing 5 kg of manure in a large iron pan. Add 0.2% to 0.5% of acid—such as sulfuric or nitric acid—to soak and ferment the mixture for about 4 to 5 hours. After that, mix in 5 kg of human urine and 10 kg of chicken and sheep droppings, and pour everything into a pot. Then add 3 kg of superphosphate to the mixture. Heat the pot over a fire, constantly stirring with a wooden stick to ensure even cooking. Once fully cooked, the mixture is left to dry. This process results in a high-nitrogen ammonium phosphate compound fertilizer, ideal for topdressing crops and providing essential nutrients quickly.
