Along with the population increasing, also more and more demand for meat, all kinds of large and small farms are more and more, in the case of meet the demand of the meat, but also produced a large number of livestock and poultry dung, feces reasonable treatment can not only effectively solve the problem of environmental pollution, also can turn, generate considerable income, At the same time also formed a standardized agricultural ecosystem. So what is the better way to deal with it? The answer, of course, is to turn animal manure into organic fertilizer. The specific methods are as follows
First, compost preparation
No matter what kind of animal manure, if you want to transform into organic fertilizer, the most important step is the fermentation of raw materials. The process of hot composting can kill all kinds of harmful bacteria, weed seeds and worm eggs in the raw materials, which is necessary to promote the propagation of beneficial microorganisms, deodorization and harmless treatment. After complete fermentation, the animal and poultry manure can reach the standard processing of organic fertilizer. So, what problems should be paid attention to in procedure of composting?
First of all: control the carbon nitrogen ratio of raw materials
Generally speaking, it is necessary to match the ratio of raw materialsin the process of proper composting. For example, chicken manure raw materials have a high nitrogen content, and about 30% straw materials can be added to improve the overall carbon content of raw materials. Reasonable c/N ratio is the precondition of fermentation temperature rise, otherwise it will lead to fermentation failure. A reasonable c/N ratio is about 25:1.
Next: control raw material moisture
The moisture content of raw materials is also an important indicator before fermentation, too much water is too poor between the molecules of raw materials, which is not conducive to air circulation, so that raw materials can not fully combine with oxygen. Too little water is not conducive to the growth of beneficial microorganisms. Reasonable water content should be controlled at about 55%.
Finally: control fermentation temperature
Raw materials fermentation temperature for heating, high temperature, constant temperature, cooling four stages, using compost turning equipment fully contact with oxygen, accelerate the heating process, high temperature when using cast machine control temperature 70 ℃, avoid high temperature harm beneficial bacteria, entered the stage of constant temperature, then slowly into the cooling stage, when the material is beige, odourless, slightly sweet, namely complete fermentation.
Through strict and standardized harmless treatment, livestock and poultry manure can be transformed into high-value organic fertilizer, of course, if you want to reach the standard of commodity organic fertilizer, it is also necessary to carry out further processing, but also need to use the relevant organic fertilizer making machine t to cooperate.
