"The land is fed by manure, and the seedlings grow by manure." Chicken manure is an important raw material of organic fertilizer, which has the advantages of high nutrient content, comprehensive nutrient and fast fertilizer effect. But in fact, the development of chicken manure organic fertilizer did not go smoothly at the beginning. Some people worry that soil residues of antibiotics will affect human health if they enter the human body through food. Why is that? Antibiotics and heavy metals in chicken manure are often high, and antibiotics are mainly derived from feed. Due to the high density of chicken breeding, high epidemic prevention requirements, the use of antibiotics in livestock and poultry is relatively large, and the chicken's digestive tract is short, very few farms add antibiotics in feed, and it is easier to discharge through feces. But there is no need for such fears now. Antibiotics can be degraded by industrial means. Chicken manure organic fertilizer production line using composting treatment process (mainly aerobic compost), after organic fertilizer equipment high temperature, fermentation, basically can degrade 60% to 70% of the antibiotics in chicken manure, to meet the requirements of harmless treatment. Chicken manure organic fertilizer is generally used as a base fertilizer for cash crops such as vegetables and fruit trees, which can effectively improve crop quality and improve soil structure.
