The characteristics of chemical fertilizers are high nutrient content and fast fertilizer efficiency, but the duration is short and the nutrients are single. If mixed with organic fertilizer, it can be used to complement each other.
1. Meet the needs of nutrients in crop growth stages.
2, can improve fertilizer efficiency. After the fertilizer is applied to the soil, some nutrients are absorbed or fixed by the soil. When mixed with farmyard manure, it can reduce the contact surface between chemical fertilizer and soil, thereby reducing the proportion of chemical fertilizer fixed by soil and improving the effectiveness of nutrients.
3, can save nutrients, reduce loss, improve the absorption of nutrients by crops. After application of chemical fertilizers, it will affect the absorption of nutrients and water by crops and accelerate the loss of nutrients. If mixed with organic fertilizer, it can promote the absorption of nutrients and water by crops.
4. It can effectively adjust soil pH and improve soil structure. On alkaline soils, the application of acidic fertilizers will result in soil compaction and enhanced acidity. If mixed with organic fertilizer, it can effectively adjust the acidity and alkalinity.
5, can increase soil nutrients and improve soil vigor. Farmyard manure is the energy source of microbial life, and fertilizer is the inorganic nutrient that supplies microbial growth and development. The combination of the two can promote the activity of microorganisms, thereby promoting the decomposition of organic fertilizer. Soil microbial activity can increase soil nutrients, increase soil vigor, and promote crop growth.
Second, the scientific mix of organic fertilizer and inorganic fertilizer
1. Combination of human excrement and ferrous sulfate: 500 g to 600 g of ferrous sulfate per 100 kg of human excrement can convert ammonium carbonate in human excrement into stable ammonium sulfate to protect fertilizer. Stinky, prevent the loss of nitrogen volatilization.
2, human excrement with superphosphate: add 5 kg of superphosphate per 100 kg of human excrement, stir evenly and store for 3 days - 10 days, can convert the highly volatile ammonium carbonate in human waste into The stable nature of ammonium phosphate, thereby increasing the elements of phosphorus in human excrement, with phosphorus and nitrogen, the fertilizer effect is greatly increased.
3, grass ash and superphosphate with: 6 kg of grass ash soaked in water 30 kg, plus 2 kg of calcium phosphate, 6 hours later, add 100 kg of water and mix well, after standing sedimentation, take the clear liquid spray, you can get The same fertilizer effect as potassium dihydrogen phosphate.
4. Mixing of compost and ammonium bicarbonate: weeding weeds, plant stems, leaves, etc. into pieces, adding 0.5% to 1% of ammonium bicarbonate and human excrement, and then sealing with mud, fully decomposed It becomes an efficient biological potassium fertilizer.
5, the combination of manure and superphosphate: the feces taken out in the livestock circle, add 20% of superphosphate and mix well, after stacking for 20 days, not only can prevent the loss of nitrogen nutrients in the manure, but also accelerate the maturity of the manure, increase The content of available phosphorus.
