In agricultural production, the use of organic fertilizer equipment to process organic fertilizer is becoming more and more common. However, if used incorrectly, it can have a range of negative effects on the environment, soil and crops.

1. Overuse of organic fertilizers can lead to soil acidification. Some organic fertilizers, such as animal manure, contain large amounts of organic acids. If these acids are not effectively neutralized by the soil's natural buffer system, they can cause soil acidification and affect crop growth.

2, organic fertilizer decomposition process will produce methane and carbon dioxide and other greenhouse gases, if used in excess, will increase the greenhouse gas content in the soil, aggravate global warming.

3, some heavy metals in organic fertilizers may not be completely decomposed, with the absorption of crops into the food chain, may cause potential harm to human and animal health.

4, if the organic fertilizer is not properly handled, it may spread diseases and pests. Organic fertilizer that has not been filtered or fermented in the organic fertilizer production line may contain eggs and pathogens, and direct use may lead to crop infections and pests, increase the use of pesticides, and have adverse effects on the environment and the crops themselves.
