In agricultural production, chicken manure is a valuable organic resource. Through scientific composting, it can be converted into fertile organic fertilizer to help crop growth. However, if the composting method is improper, it will not only fail to play its role, but may also cause problems such as odor, pests and diseases. For novices, it is crucial to master the correct steps of chicken manure composting. With professional composting equipment and technology, Huaxin Fertilizer Machinery simplifies the composting process for you, improves the efficiency and quality of composting, and makes it easier to turn chicken manure into treasure.
Preparation of materials required for composting
1. Core raw materials: chicken manure
Chicken manure is rich in nitrogen, phosphorus, potassium and other nutrients, and is a key raw material for composting. When collecting, try to choose fresh chicken manure without too many impurities. It should be noted that untreated raw chicken manure contains a large number of pathogens, insect eggs and salt, and direct application will cause harm to crops, so it must be composted.
2. Carbon source materials: straw, sawdust, etc.
In order to balance the carbon-nitrogen ratio (C/N) of composting, carbon source materials need to be added. Common ones include rice straw, wheat straw, sawdust, corn cobs, etc. These materials can effectively absorb moisture from chicken manure, improve the air permeability of compost, and avoid excessive ammonia and odor during the composting process. Generally speaking, the volume ratio of chicken manure to carbon source materials is controlled at 1:2 – 1:3.
3. Green manure materials: grass, vegetable leaves, etc.
Green manure materials are rich in moisture and easily decomposed organic matter, which can provide energy for microbial activity in the early stage of composting. You can choose grass, vegetable leaves, vines, etc., but avoid using plant residues with pests and diseases. Chopping green manure materials and mixing them into compost can speed up the composting process.
Detailed explanation of composting stages
1. Active Phase: High temperature and rapid decomposition
In the early stage of composting, microorganisms quickly decompose organic matter, releasing a large amount of heat, causing the compost temperature to rise rapidly to 140 – 160°F (about 60 – 71°C), and this stage lasts for 2 – 3 weeks. High temperature can effectively kill pathogens, insect eggs and weed seeds in chicken manure to ensure the safety of composting.
To maintain a high temperature environment, the following points should be noted:
- Regular turning: Use tools to turn the compost every 2-3 days to ensure oxygen supply and promote microbial activity. Huaxin Fertilizer Machinery’s automatic turning machine can achieve efficient turning, save manpower, and turn evenly, so that the compost is heated more fully.
- Control moisture: The ideal moisture content of compost is 50%-60%. Too dry or too wet will affect the activity of microorganisms. If the surface of the compost is dry and white, you can spray water appropriately; if there is too much water, you can add dry materials such as straw to adjust.
2. Curing Phase: Stable maturation
After the active phase, the compost enters the curing phase, which lasts for 30-60 days. At this time, the compost temperature gradually decreases, the microbial activity slows down, and the organic matter is further decomposed and converted into stable humus. At this stage, the frequency of turning the compost can be reduced, and it can be turned every 7-10 days. Over time, the volume of the compost gradually decreases, the color becomes darker, and the texture becomes loose.
Solutions to Common Problems
1. Odor Control
The generation of odor during composting is a common problem for novices. The main reason is an imbalance in the carbon-nitrogen ratio or insufficient oxygen. The solutions are as follows:
- Add carbon source: When the compost has a pungent odor, add materials with high carbon content such as sawdust and rice husks in time to absorb odorous gases such as ammonia. Enhance ventilation:
- By turning the compost or using composting equipment with a ventilation system (such as Huaxin’s forced ventilation composting box), increase the oxygen content in the compost, promote the growth of aerobic microorganisms, and reduce the odor produced by anaerobic fermentation.
2. Pest and disease management
To prevent pest breeding and disease spread, it is necessary to pay attention to:
- Avoid adding perishable and insect-attracting materials such as meat and oil.
- Keep the compost dry: A humid environment is easy to attract pests such as flies and grubs. If the compost is too wet, add dry materials in time to adjust it, and ensure that the compost pile has good drainage.
Check whether the compost is mature
- Appearance and texture: The mature compost is dark brown, loose in texture, similar to soil, without obvious chicken manure or other raw material forms, and has the natural smell of soil, rather than a pungent odor.
- pH value detection: Use pH test paper or a detector to measure the pH value of the compost. The ideal range is between 6.5 and 7.5. Too high or too low pH values will affect soil and crop growth.
- Temperature test: Insert the thermometer into the center of the compost. If the temperature is close to the ambient temperature, the compost is mature. If it is still high, it needs to be piled up.
