What's the effect of chemical fertilizer with organic fertilizer?

What's the effect of chemical fertilizer with organic fertilizer? Please give guidance to chemical fertilizer with organic fertilizer application effect is good, details can refer to the following list: first, chemical fertilizer and organic fertilizer use benefits 1, can improve fertilizer efficiency such as calcium superphosphate, trace elements and other fertilizers, applied into the soil fixed by the soil and failure. When mixed with organic fertilizer, due to the reduction of the contact surface with soil and the fixation of nutrients, organic fertilizer can improve the solubility of phosphate rock, which is better under paddy field conditions. After many chemical fertilizers are mixed with organic fertilizers, chemical fertilizers can be absorbed and preserved by organic fertilizers to reduce loss. In addition, chemical fertilizer mixed with organic fertilizer can also promote the maturity of organic fertilizer and improve fertilizer efficiency. The results showed that the combined use of chemical fertilizer and organic fertilizer could not only reduce the redox potential of soil, reduce the nitrification of ammonia, but also reduce the volatilization loss of nitrogen. Generally, the nitrogen use efficiency can be increased by 10% to 15%. 2. It can reduce some adverse side effects of chemical fertilizer. When a large amount of chemical fertilizer or uneven chemical fertilizer is applied alone, the concentration of soil solution is high, which affects crop water absorption and even root damage. If mixed with organic fertilizer, this problem will not occur. In addition, if physiological acid fertilizer is applied alone for a long time, the soil will become acidic, resulting in excessive active iron, active aluminum and other harmful substances, causing toxicity to crops. The mixed application with organic fertilizer can increase the buffering capacity of soil and prevent soil acidification. For example, some calcium superphosphate contains too much free acid, which will affect seed germination and seedling growth when making seed fertilizer. After adding organic fertilizer, it can neutralize free acid and reduce the damage to seeds. 3. It can increase crop nutrition, organic fertilizer contains more nutrients, fertilizer effect is stable and long, contains more organic matter, can increase the content of soil organic matter and improve soil physical and chemical properties. It can supply not only crops, but also soil microorganisms with nutrients such as nitrogen, phosphorus, potassium, vitamins and growth hormone. After the application of organic fertilizer, the soil enzyme activity was enhanced, which was beneficial to the transformation of nutrients. For example, the mixture of organic fertilizer and calcium superphosphate or magnesium superphosphate fertilizer can promote the growth of autogenic nitrogen-fixing bacteria in soil and increase crop nitrogen nutrition. According to the experiment, the content of organic matter, ammonifying bacteria, aerobic nitrogen-fixing bacteria and cellulose decomposing bacteria increased by 0.08%-0.11%, 260%, 119% and 600% respectively in the plots with chemical fertilizer and organic fertilizer for 3 years. 4. when straw is returned to the field and immature organic fertilizer is applied, the addition of chemical nitrogen fertilizer can avoid the slow supply of crops due to the lack of nitrogen in the early stage, and cereal crops need to provide nitrate nitrogen and ammonium nitrogen at the same time at the mature stage. Organic fertilizer can do this. 2. The requirements for the combined use of chemical fertilizer and organic fertilizer 1. Grasp the application time, the amount of organic fertilizer is large, and the effect is slow, so it should be applied as early as possible, generally, the base fertilizer should be applied once before sowing, while the amount of chemical fertilizer is less and the effect is quick. generally, it should be applied about 7 days before the crop needs fertilizer. 2. To master the application method, organic fertilizer should be combined with deep ploughing and raking into the soil ploughing layer. Nitrogen fertilizer used in combination with organic fertilizer should be used as base fertilizer or topdressing, while phosphate fertilizer can be used as base fertilizer together with organic fertilizer. 3. To control the amount of fertilizer, the amount of chemical fertilizer used in combination with organic fertilizer can vary according to the fertility of crops and soil. For example, in low-fertility soil, 1000-1500 kg of organic fertilizer, 10-15 kg of urea, 40-45 kg of compound fertilizer and 10-12 kg of potassium chloride can be applied per mu, while on medium-fertility soil, 500-1000 kg of organic fertilizer can be applied per mu. Urea 8kg, compound fertilizer 35kg, potassium chloride 8kg On high fertility soil, 500 kg of organic fertilizer, 6 kg of urea, 35 kg of compound fertilizer and 6 kg of potassium chloride can be applied per mu.
