With the increasing number and scale of chicken farms and more and more chicken manure, how can chicken manure be used to generate revenue?
Although chicken manure is a relatively high-quality organic fertilizer, it cannot be applied directly without fermentation. When chicken manure is applied directly to the soil, it will ferment directly in the soil, and the heat generated during fermentation will affect crops. The growth of fruit seedlings will burn the roots of crops, which is called root burning.
In the past, some people used chicken manure as feed for cattle, pigs, etc., but it was also due to the complicated process. It is difficult to use on a large scale; some people also dry chicken manure, but drying chicken manure consumes too much energy, the cost is too high, and it is not a sustainable development model.
After people’s long-term practice, chicken manure fermentation is still a relatively feasible method. Chicken manure fermentation is divided into traditional fermentation and microbial rapid fermentation.
一.The traditional fermentation
Traditional fermentation takes a long time, generally 1 to 3 months. In addition, the surrounding stench is unpleasant, mosquitoes and flies breed in large numbers, and the environmental pollution is very serious. When the chicken manure is wet, it needs to be supplemented, and more labor is required. In the fermentation process, it is a relatively primitive method to use a raking machine to turn the rake.
Although the equipment investment of traditional fermentation is relatively low, the cost of using traditional fermentation to process 1 ton of chicken manure is also relatively high under the current high labor costs, and traditional fermentation will be eliminated in the future.
