The content of antibiotics and heavy metals in chicken manure is often high, and antibiotics mainly come from feed. Due to the high density of chicken farming and high requirements for epidemic prevention, the use of antibiotics in livestock and poultry is relatively high. In addition, the short digestive tract of chickens makes it easier for very few farms to add antibiotics to their feed and excrete them through feces. After thorough fermentation of chicken manure, it is a relatively high-quality organic fertilizer with rich nutrient content. It contains both a large amount of organic matter and a high content of three essential nutrients, making it an efficient organic fertilizer.
Small organic fertilizer production lines require essential equipment such as organic fertilizer crushers, organic fertilizer mixers, organic fertilizer granulators, organic fertilizer screening machines, belt conveyors, and granulators. The small-scale organic fertilizer production line has low energy consumption, small floor area, no odor in the operating environment, zero pollution, good ventilation, and deodorization in only 1-2 days. The organic fertilizer production line has a compact structure and advanced technology. It uses harmless live bacterial preparations to treat livestock and poultry manure, and undergoes biological fermentation under the action of various beneficial microorganisms. After fully decomposing the organic matter, nutrients are released, and the resulting biological heat and high-temperature fermentation process can kill bacteria and insect eggs, detoxify and deodorize, purify the environment, and achieve harmless, resourceful, and industrialized treatment. The energy consumption is low, and the product quality is stable.
If professional organic fertilizer production lines are not used to thoroughly ferment chicken manure, when the appropriate temperature and humidity are reached, the chicken manure begins to ferment, and the heat generated will burn seedlings, rot roots, black roots, yellow leaves, yellowing, and in severe cases, cause plant death. Especially in winter and spring, the use of chicken manure poses the greatest safety hazard, as the temperature inside the greenhouse is high and the fermentation of chicken manure releases a large amount of heat, leading to root burning. The organic fertilizer production line utilizes composting treatment technology (mainly aerobic composting), and after high temperature and fermentation, it can basically degrade 60% to 70% of antibiotics in chicken manure, meeting the requirements of harmless treatment. Chicken manure organic fertilizer is generally used as base fertilizer for cash crop such as vegetables and fruit trees, which can effectively improve crop quality and soil structure.
