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 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. Here are some self-made methods for high-efficiency soil fertilizers:
1. Ammonia water 50 kg of fresh cow dung, 50 g of soy flour, 5 kg of cooked gypsum powder, sealed under 25 degrees for 3 days, applied to 3 times of water, the fertilizer effect is higher than ammonia.
2. Ammonium sulphate ammonium sulphate 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.
3. The soil compound fertilizer is first crushed and sieved by superphosphate. Then, according to 100 kg of superphosphate, 120-150 kg of human urine is evenly mixed, and then piled into a conical shape. The seal is tightly sealed with 3 cm thick mud, and stacked 7 It can be used in days, and the fertilizer effect is ideal. Be careful not to pile up in the lower part to prevent water immersion. This kind of soil compound fertilizer can be used as base fertilizer, top dressing and seed fertilizer. As a base fertilizer, it can be mixed with manure and soil; if it is used as a seed fertilizer, it should not be in contact with the seed to prevent germination. When it is used as a top dressing, it can be applied or applied, 1 cm away from the root of the crop to prevent burning of the seedlings. strict.
4, soil potassium dihydrogen phosphate potassium superphosphate and hot water in a ratio of 2:5, stir evenly for 48 hours, filtered for use; plant ash and hot water in a ratio of 6:15, stir and evenly stand for about 10 minutes, after filtration The two filtered solutions are then mixed to form a crude solution containing potassium dihydrogen phosphate with the same effect as potassium dihydrogen phosphate.
5, soil nitrogen ammonia phosphorus compound fertilizer with animal bone processing into bone powder, is an important slow-acting agricultural fertilizer, generally used as a base fertilizer, there are raw bone powder and cooked bone powder. Raw bone powder is a powder obtained by simply cooking the bone and removing a part of fat and pulverizing it, which contains 2-6% nitrogen and 15-28% phosphorus pentoxide. It is a high-slipping nitrogen-phosphorus compound fertilizer. The cooked bone powder (also known as defatted bone powder) is a bone obtained by solvent extraction of fat, and then pulverized by high-temperature cooking, which contains nitrogen 1.5-5, containing phosphorus pentoxide 16- 25%, its fertilizer efficiency is also higher.
