| titleOfInvention | Preparation method of nitrogen and potassium organic composite fertilizer |
| abstract | The invention discloses a preparation method of a nitrogen and potassium organic composite fertilizer. The preparation method comprises preparation of an organic potassium fertilizer, proportion of the organic potassium fertilizer and a urea fertilizer and fermentation of an organic composite fertilizer. The preparation of the organic potassium fertilizer comprises the following steps: crushing waste materials after crops are harvested; then, adding urinate of people and livestock and uniformly mixing; placing the mixture in a pool and compressing and sealing so as to naturally ferment for 15 days, thereby forming the natural organic potassium fertilizer; after mixing the organic potassium fertilizer and the urea fertilizer at a ratio of 7:1, placing the mixture in the pool again to hermetically ferment for 7 days so as to enable the urea phosphorus fertilizer to be seeped to the organic potassium fertilizer. The nitrogen and potassium organic composite fertilizer is simple in preparation method and convenient to prepare, and waste materials of crops can be effectively utilized for preparing the organic fertilizer, so that the environmental pollution is reduced, the production cost of agricultural products is lowered, and the quality and yield of the planted agricultural products are improved. |
