Organic fertilizer and acid fertilizer

The combination of alkaline bio-organic fertilizer and acid fertilizer has obvious synergistic effect. Under different raw materials and processes, the PH value of organic fertilizer is also different. At present, the relatively pure organic fertilizers in China are mainly organic fertilizers made of chicken manure, among which the bio-organic fertilizer produced by Shandong Minhe Biotechnology Co., Ltd. is pure, and Minhe bio-organic fertilizer is made of high-quality chicken manure produced by its parent company Minhe Animal Husbandry. Using domestic advanced equipment, through high-temperature fermentation, deodorization, beneficial bacteria and other processes, the total nutrients of nitrogen, phosphorus and potassium in the original ecology are as high as 8%, and the organic matter is over 50%, which is neutral and slightly alkaline. After mixed use of chemical fertilizer and organic fertilizer, chemical fertilizer can be absorbed and stored by organic fertilizer, reducing losses, and mixing chemical fertilizer and organic fertilizer can also promote further decomposition of organic fertilizer and improve fertilizer efficiency. The results show that the combined application of chemical fertilizer and organic fertilizer can not only reduce the oxidation-reduction potential of soil, reduce the nitrification of ammonia, but also reduce the volatilization loss of ammonia, and generally improve the utilization rate of nitrogen fertilizer 10%- 15%. However, decomposed organic fertilizer should not be mixed with alkaline fertilizer because mixing with alkaline fertilizer will cause ammonia volatilization and reduce the nutrient content of organic fertilizer.
