Earth-based quick-effect compound fertilizer two methods

Earth-based quick-release compound fertilizer two-in-one five-in-one quick-effect compound fertilizer: According to a ratio of 1:10, the plant ash and soft water (river water, pond water) are poured into a pot to boil, and an aqueous alkali solution is obtained after filtering out impurities. Pour the bovine bone powder and soft water into the pot at a ratio of 1:7. Boil the impurities and remove the filtrate. A ratio of 1:3 was formulated as a saline solution. Put the plaster in the stove at high temperature and then grind it into powder for later use. Put 30% alkaline aqueous solution in the pot first, and after boiling, 13% bovine bone water, 2% salt solution, and 30% gypsum powder are poured into the pot together (while pour it down while stirring), boil Cook for a further 10 to 15 minutes, and then pour the quicklime with the mixed solution (the quicklime can be piled on the cement floor) until the quicklime is powdered. According to the above method, each 50 kilograms of mixed raw materials can be used to make 23 kilograms of five-in-one compound fertilizer with the contents of nitrogen, iodine, and potassium being 28%, 0.5%, and 30%, respectively, which can be used as base fertilizer and top dressing.

Preparation of ammonium phosphate quick-acting compound fertilizer: Take 5 kg of large manure and pour it into a large iron pan. Add 0.2% to 0.5% of acid (sulfuric acid, nitric acid may be appropriate) to make it soaked and fermented. About 4 to 5 hours later, 5 kg of human urine and 10 kg of chicken and sheep droppings are mixed thoroughly and poured into a pot. Then, 3 kg of superphosphate is added to the pot. Then, the iron pan is heated, and it must be stirred with a wooden stick in the pan while cooking, and the cooked food in the pan is ready to dry. The ammonium phosphate compound fertilizer produced by the above method has a high nitrogen content and is suitable for crop topdressing.
