Decomposition Technology of Raw Chicken Manure Composting

Can chicken manure be used as organic fertilizer if it is not ripe? Chinese style
Answer: No.
1. Not only chicken manure, but also human manure contains a lot of pathogens, eggs and parasites. Unripe manure can not be directly applied to crops.
2. Chicken manure will dissipate most of the heat in the process of ripening. If it is not fertilized directly, it will cause burning roots and seedlings of plants.
3. Nitrogen fertilizer in chicken manure originally existed in the form of protein. Plants could not use protein directly. Only when protein was decomposed into ammonia after fermentation, can they be used by plants.

How to decompose chicken manure?

Chicken manure must be fully decomposed before it is applied. The parasites and eggs in chicken manure, as well as some infectious pathogens, are inactivated through the decomposition process. Because chicken manure produces high temperature in the process of decomposition, it is easy to cause nitrogen loss. Therefore, it is better to add water and 5% calcium superphosphate before chicken manure is decomposed. Chicken manure has become a good base fertilizer for crop cultivation after full maturation. It can be used for all kinds of flowers, seedlings, crops and fruit trees.

The traditional method is to compost chicken manure for fermentation and maturation, which usually takes 3-4 months to mature. Nowadays, through the rapid biological decomposition technology of Nongshengle chicken manure, the decomposition rate can be 10-20 times faster than the traditional method by aerobic fermentation, and the protein and other substances of chicken manure can be converted into more easily absorbed elements such as nitrogen, phosphorus and potassium. After complete decomposition, chicken manure can hardly smell odor. Fermentation of chicken manure with Nongshengle Fecal Fermentation Fermentation Fermentation Fermentation Fermentation Fermentation has the advantages of low dosage, good effect and fast speed. Generally, chicken manure can be completely decomposed in 7-15 days. If the fermentation material is pure chicken manure, under normal conditions, the C/N ratio is generally less than 20, it should be added with appropriate amount of straw, sawdust and other materials with high C/N ratio. Straw can be added as much as chicken manure to mediate the C/N ratio, and because compost fermentation is aerobic fermentation, straw can enhance the looseness and permeability of chicken manure, which is more conducive to fermentation.

Note: It is recommended to use rice, corn, wheat, sawdust and other plant straw with larger carbon and nitrogen content, and to avoid using straw with smaller carbon and nitrogen content, such as beans. Chinese style

Method of decomposition of chicken manure: Before fermentation, mix all kinds of materials evenly and reserve them. During fermentation, the manure starter of Nongshengle was diluted and mixed with chicken manure mixture at the ratio of 1:200. Then it could be accumulated and fermented. The fermentation process is dumped 1-2 times, and the decomposition can be completed in 7-15 days according to the season.
Knowledge of organic fertilizer clinker: The ratio of total carbon content to total nitrogen content in organic matter is called carbon-nitrogen ratio, and their ratio is called carbon-nitrogen ratio.

C/N ratio of common plants:

• In general, the C/N ratios of gramineous crop stalks such as rice stalks, corn stalks and weeds are very high, reaching 60-100:1.
• The C/N ratio of leguminous crop stalks is relatively small, such as the C/N ratio of general leguminous green manure is 15-20:1.

Effects of different C/N ratios on Composting

The decomposition and mineralization of organic matter with high C/N ratio is difficult or slow. The reason is that when microorganisms decompose organic matter, they need to assimilate about one part of nitrogen to form their own cell body when they assimilate five parts of carbon, because the carbon-nitrogen ratio of microorganisms is about 5:1. In order to assimilate (absorb and utilize) one portion of carbon, four portions of organic carbon are needed to obtain energy, so 25 portions of organic carbon are needed for microorganisms to absorb and utilize one portion of nitrogen. That is to say, the ratio of carbon to nitrogen of microorganism decomposition of organic matter is 25:1. If the ratio of carbon to nitrogen is too large, the decomposition of microorganisms will be slow and the available nitrogen in soil will be consumed. Therefore, when applying organic fertilizers (such as rice straw) with high C/N ratio or composting materials with high C/N ratio, more N-containing fertilizers should be added to regulate C/N ratio. On the contrary, there are too many nitrogen elements in chicken manure, so more carbon elements such as straw should be added. Chinese style

How to reduce the use cost of chicken manure ripening agent:

In order to reduce the use cost of chicken manure ripening agent, the manure fermentation strain (original strain) was developed and manufactured. Users could use the manure fermentation strain to cultivate the fermentation agent by themselves, which could reduce the cost by 10 times. Chinese style

Benefits of Feed Fermentation

• Increase feed utilization rate and reduce feeding cost;
• Detoxification and detoxification, improve palatability and intake;
• Improving animal immunity and reducing fecal discharge;
• Enhance meat quality and flavor to make meat delicious.
