Scientifically matching organic fertilizers with inorganic fertilizers can not only prevent the volatilization of active ingredients, but also greatly increase fertilizer efficiency. First, the scientific mix of organic fertilizer and inorganic fertilizer 1. Human waste and ferrous sulfate with. Adding 500-600 grams of ferrous sulfate per 100 kilograms of human fecal urine can convert ammonium carbonate in human excreta into stable ammonium sulfate, which acts as a nutrient and deodorizer to prevent nitrogen from escaping. 2, human excrement and superphosphate with. Add 5 kg superphosphate per 100 kilograms of human excrement and store for 3 to 10 days after mixing evenly, which can make the highly volatile ammonium carbonate in human waste and urine convert into stable ammonium phosphate, thus increasing human excrement and urine Phosphorus element, phosphorus nitrogen, fertilizer effect greatly increased. 3, plant ash and superphosphate with. With plant ash 6 kg watered 30 kg soaked, plus 2 kg of superphosphate, 6 hours and then add 100 kg of water and mix well, after standing and taking the liquid spray, you can get the same fertilizer effect as potassium dihydrogen phosphate. 4, heap fertilizer with ammonium bicarbonate. The weeds, plant stalks, leaves, etc. were crushed into pieces, 0.5% - 1% of ammonium bicarbonate was added and human urine was piled up and tanned, and then covered with mud and sealed, and fully decomposed, it became a highly efficient biological potash fertilizer. 5, with fertilizer and superphosphate with. Adding 20% ​​of superphosphate to the excrement in the livestock circle and mixing it for 20 days will not only prevent the loss of nitrogen nutrient in the manure, but also accelerate the decomposed process of manure and increase the content of available phosphorus. Second, the organic fertilizer and inorganic fertilizer mix the benefits of 1, can be a comprehensive supply of nutrients needed for crop growth. Fertilizer is characterized by high nutrient content and rapid fertilizer effect, but short duration and single nutrient; therefore, the combination of the two can be used to meet the needs of nutrients during various growth periods of crops. 2. It can reduce nutrient fixation and further increase fertilizer efficiency. After the fertilizer is applied to the soil, some nutrients are absorbed or fixed by the soil, which reduces the effectiveness of nutrients. When mixed with farmyard fertilizers, it is possible to reduce the contact area between fertilizers and soil, thereby reducing the fixation of fertilizers to the soil and improving the effectiveness of nutrients. 3, can preserve nutrients, reduce loss, improve crop nutrient absorption. The solubility of chemical fertilizers is large. After application, it will cause higher osmotic pressure on the soil and affect the absorption of nutrients and water by crops. This increases the chance of nutrient loss. If mixed with organic fertilizer, this drawback will be solved, and promote crop absorption of nutrients and moisture. 4, can effectively regulate the soil pH, improve soil structure. In alkaline soils, only acidic fertilizers are used. After ammonium is absorbed, the remaining acid radicals combine with hydrogen ions in the soil to form acids, which can lead to soil compaction, acidity, and soil structure destruction. If used in combination with organic fertilizers, this contradiction is resolved. This is because organic fertilizers can relieve the buffering capacity of the soil and effectively regulate acidity and alkalinity so that the acidity of the soil does not increase. 5, can increase soil nutrients, improve soil vitality. Farmyard manure is an energy source for microbial life. Fertilizer is an inorganic nutrient for the growth and development of microorganisms. The combination of the two can promote the activity of microorganisms, thereby promoting the decomposition of organic fertilizers. Soil microbial activity can also increase the growth of various stimulants, such as vitamins, biotin, niacin, etc., increase soil nutrients, increase soil vigor, and promote crop growth.
