Several efficient fertilizer preparation methods

At present, the price of fertilizer has increased and the cost of agriculture has increased. Such as homemade soil fertilizer can greatly reduce costs. The self-made soil chemical fertilizer has a wide range of raw materials, simple method, economical and practical, and its fertilizer efficiency is no less than that of chemical fertilizer. Now we introduce several self-made methods of high-efficiency soil fertilizer for reference by farmers.

Ammonia water 50 kg of fresh cow dung, 50 g of soy flour, 5 kg of cooked gypsum powder, sealed at 25 ° C for 3 days, applied to 3 times of water, the fertilizer effect is higher than ammonia.

Ammonium sulfate, human urine 50 kg, 5 g of plaster, 25 kg of water, mixed and mixed, applied after 10 days of closure, the fertilizer effect is equivalent to ammonium sulfate.

The soil compound fertilizer firstly pulverizes the superphosphate, and then mixes 100-kg of superphosphate with 120-150 kilograms of human urine, then piles it into a conical shape, and seals it tightly with 3 cm of mud, and stacks it for 7 days. It can be used, and the fertilizer effect is ideal. Be careful not to pile up at low places to prevent water immersion; this kind of soil compound fertilizer can be used as base fertilizer, top dressing, and seed fertilizer. The base fertilizer can be divided into sputum fertilizer and soil mixed fertilizer; when seeding fertilizer, do not contact with seeds to prevent influence. Germination; can be applied or applied in the topdressing, from the root of the crop to prevent burning, and the soil should be strict after application.

Soil potassium dihydrogen phosphate potassium superphosphate and hot water in a ratio of 2:5, stir evenly for 48 hours, filter for use; plant ash and hot water in a ratio of 6:15, stir and let stand for about 10 minutes, filter and then The two filtered solutions are mixed into a crude solution containing potassium dihydrogen phosphate with the same effect as potassium dihydrogen phosphate.

The soil nitrogen-phosphorus compound fertilizer is processed into bone powder by animal bones. It is an important late-effect agricultural fertilizer. It is generally used as a base fertilizer. It is divided into raw bone powder and cooked bone powder. The bone powder is simply cooked by removing bone and removing some fat. The powder, which contains 2%--6% nitrogen, contains 15%-28% phosphorus pentoxide, is a high-efficiency nitrogen-phosphorus compound fertilizer; steamed bone powder (also known as defatted bone powder) is the bone after solvent extraction of fat It is then pulverized by high temperature cooking, which contains 1.50%-5% nitrogen. Containing phosphorus pentoxide 16% -25%, its fertilizer efficiency is also higher.
