At present, most of the organic fertilizers applied by growers to the farmland are naturally piled with livestock manure for a few days and then applied to farmland. In fact, there are great hidden dangers in doing so, especially since the manure cannot be fully decomposed. During the natural piling period, allowing wind, sun and rain not only causes serious loss of nutrients, but also causes environmental pollution. Casting farmland can also cause burning of seedlings and even cause death of crops. There are five major hazards to the direct application of unripe organic fertilizer to farmland: 1. The pests and threats include coliforms, nematodes, and other pests and diseases. Direct use can lead to the spread of diseases and pests, crop disease, and the health of people who eat agricultural products. It will also have an impact; when unfermented organic matter is fermented in the soil, it will easily breed pathogens and pests, leading to the occurrence of plant diseases and insect pests. 2. The burning of rootless livestock and poultry manure is applied to the farmland. Because the fermentation is not complete, “secondary fermentation†occurs. When the fermentation conditions are met, the fermentation of raw manure is performed under the action of microorganisms; when the fermentation site When it is close to the root or when the crop plants are small, the heat generated by the fermentation will affect the growth of the crop, causing "burning of roots and burning of seedlings", and in severe cases it will lead to plant death. 3, poisonous gas harm unfamed feces produce methane, ammonia and other harmful gases in the process of decomposition, so that the soil and crops produce acid damage and root damage. 4. Decomposition of soil in the absence of oxygen in the decomposed soil will consume oxygen in the soil and temporarily leave the soil in an anoxic state. Under such an anoxic condition, the growth of the crop will be inhibited. 5. Nutrient loss In the traditional process of stacking excrement, the loss of nutrients such as nitrogen, phosphorus and potassium is very serious due to natural decomposition, wind and rain, and the general utilization rate is only 50%.
6. Slow fertilizer effect The nutrients in unfermented and decomposed organic fertilizers are mostly organic or slow-acting. They cannot be directly absorbed and utilized by crops. They can only be absorbed and utilized by crops if they are decomposed and transformed into quick-effect states. Therefore, direct application without fermentation will slow down the effect of the fertilizer. It can be seen that raw manure or unfammed livestock and poultry excrement can not be directly applied to farmland. It is best to choose a special brand of fermentation agent such as: Kinpo fertilizer starter, fermentation function "wild", "mighty", "fast "It is a special microbial fermentation agent for the production of organic fertilizers that meets the requirements of national environmental protection and green food production materials. It has wide applicability and can be used in small quantities. It can deodorize and decompose the material and complete the fermentation within one week. The organic fertilizer fermented by the use of goldfish fertilizer starter has good fertilizer effect and is safe and convenient to use, and can also promote disease resistance, fertility, and utilization of chemical fertilizers.
