Fermented and decomposed fertilizers have the following harmful effects: (1) Infectious diseases and pests. Fermented and decomposed fertilizers are mostly poultry and livestock feces, which contain many germs and pests. Direct use can lead to the spread of diseases and pests and crop diseases. When unfermented fertilizers are fermented in the soil, they can easily breed bacteria and insect pests, and also cause plant diseases and pests. (2) Fermentation without fermenting and decomposing fertilizers applied to the soil, the heat generated by the fermentation will affect the growth of the crops, leading to plant death in severe cases; (3) causing poison gas damage. Without the use of fermented and decomposed fertilizers, harmful gases such as methane and ammonia are generated during the decomposition process, so that the soil and crop produce acid damage and root damage; (4) to make the soil anoxic. Fermentation without composting consumes oxygen from the soil during the decomposition process, temporarily leaving the soil in an anoxic condition, which can inhibit crop growth. (5) Slow fertilizer effect. Unfermented and decomposed fertilizers are mostly organic or slow-acting, and cannot be directly absorbed and utilized by crops. Therefore, when the unfermented fertilizers are directly applied, the fertilizer effects are slowed down. (6) Untreated and used directly, unfermented fertilizer without bulking, low active ingredients, inconvenient transportation, and high operating costs.
