Why Use Chicken Manure as Fertilizer?
Studies have shown that chicken manure contains 2.34% nitrogen, 2.32% phosphorus and 0.83% potassium. It is the best nutrient content of all livestock manure. Sounds incredible, right? But actually, composting and pelleting your chicken manure can give you great benefits. The nitrogen, phosphorus, potassium and organic matter elements contained in chicken manure are indispensable nutrients for crop growth. Chicken manure can improve the soil environment and provide better growth space for crops. Therefore, chicken manure can not only be used as fertilizer, but also a high-quality organic fertilizer.
How to Process Chicken Manure Into Organic Fertilizer Efficiently?
Preparation Before Composting
Preparation of chicken manure and straw
Studies have shown that when the initial moisture content of aerobic fermentation is 55%-65%, the microbial activity in the compost is the largest, and the composting effect is the best. However, the moisture content of fresh chicken manure is generally around 80%. Therefore, it is necessary to add straw or other auxiliary materials to reduce moisture. If the raw material is fresh chicken manure and fresh straw, it needs to be dried. Stacked separately.
Preparation of decomposing agent
The addition of decomposing agent can speed up the composting process, increase the temperature of the compost and shorten the composting time. An average of 1t of material can use 0.5kg of fermentation agent.
Preparation of site
You can choose a suitable site according to the amount of chicken manure, and try to choose a place with flat terrain, shelter from rain and good ventilation. Generally choose warehouses, simple houses or canopies. The general composting methods are divided into trench compost and windrow compost. When you choose to compost flat, just choose a flat area, or an open space with a greenhouse. When you choose trench composting, you need to build a trench.
Composting Chicken Manure
This is the first step in turning your chicken manure into fertilizer. First of all, you need to collect your chicken manure, maybe each of us will collect chicken manure in time. Second, you need to know the water content in your chicken manure. Due to the high water content of chicken manure, it cannot be directly composted. At this time, you need to add some accessories such as straw, straw, sawdust or leaves to the chicken manure pile. On the one hand, it can reduce the moisture in your chicken manure, and on the other hand, it can adjust the carbon-nitrogen ratio. Finally, you may need some starter cultures. These inoculants can boost microbial activity in chicken manure and help heat up the compost. Did you think this was over? And of course the most important step – flipping. You have to toss your chicken manure or it won’t ferment well. At this point, you need a flipper to help you.
Crushing Chicken Manure
Composted chicken manure needs to be pulverized for better granulation. When you compost chicken manure, there may be agglomeration of chicken manure. At this time, a pulverizer is needed to break the chicken manure for granulation. The pulverized chicken manure is powdery fine particles, and the chicken manure particles produced are more beautiful.
Pelletizing Chicken Manure
The uniformly mixed raw materials can enter the granulator for granulation. Granulation is the most important step in the entire production process. Why do you need granulation? First, granular fertilizers are easier to transport, and powdered fertilizers are prone to agglomeration and moisture during transportation. Second, granular fertilizers hold nutrients longer and make fertilizers more effective. Powdered fertilizers are easily affected by external factors, such as being blown away by the wind or running off with rain. Granular fertilizers do not have these problems.
Drying and Cooling
A complete chicken manure pelleting production line also needs drying and cooling steps. This is because the temperature of the finished pellets is high and cannot be packaged directly, and needs to be cooled. The granules produced by wet granulation contain a certain amount of moisture and need to be dried before being packaged.
Packaging is the last procedure of chicken manure organic fertilizer production. Shunxin’s automatic packaging scale adopts imported sensor, which has fast packaging speed and measurement accuracy of plus or minus two thousandths.
What is the Parameters of Chicken Manure Composting?
First you need to mix wet chicken manure with rice husk or other ingredients. Next, adjust the water content of the mixture to about 60%. Finally, biological fermentation is used to heat up and sterilize, so that the moisture content of chicken manure is further reduced. In order to speed up the fermentation process, you should add the fermentation agent in the early stage of fermentation. While promoting the temperature rise of the compost, it increases the content of active microorganisms.
- Composting capacity
Daily treatment of wet chicken manure: 333t
Moisture content: 60%
Mixture specific gravity: 0.7t/m³
Mixture volume: 333/0.7~476m³
- Process parameter control
1) Raw material diameter: If the diameter of your chicken manure and auxiliary materials is less than 10mm, there is no need to crush them.
2) Moisture content: Moisture content is the primary consideration parameter for raw material adjustment. If the moisture content of the raw material mixture is already around 60%, then no adjustment is necessary.
3) C/N: C/N is an important reference parameter for raw material adjustment. C/N is controlled between 20 and 40, and the C/N of raw materials does not need to be adjusted.
4) Temperature control: The internal temperature of the stack is raised to 50-70°C and maintained for 7-10 days to meet the standard of harmless feces.
5) Turnover control: take temperature and fermentation time as basic standards. When the temperature of the pile body exceeds 70°C or above 60°C, keep it for more than 24 hours, and then you can turn the pile. The number of turnings varies with the season.
- Choose the machine
Windrow compost turner with a span of 2-3 meters or trench compost turner with a span of more than 6 meters.
- Stacking parameters
Stacking maximum width: 20m (slotted)
Maximum stacking height: 2.6m
Stacking length: 55m
Stacking number: 30
- Composting site parameters
Composting site length: 55+ 20=75m (10m running space at both ends of the stack)
Width of the composting site: 195+ 20=215m (10 meters of running space are left on both sides of the site)
Composting site area: 75mx215m=16125㎡
You should consider the ground pressure of the composting site. You should built the compost field as a flat concrete floor with a surface pressure of 1.83kg/cm2. We recommend that the ground be constructed with an inclination angle of 1° to prevent possible water accumulation.
- Technical parameters of compostingprocess
The compost turner works about 3-4 hours a day
The compost cycle is 10-20 days, turning once every two days, and turning once every day for the next ten days.
The moisture content of the finished product can finally reach about 30%.

The batching system uses computer batching, automatic batching, quantitative measurement, high measurement accuracy, easy operation and reliable operation.
Chicken Manure Organic Fertilizer Production Double Shafts Horizontal Mixer
Why do you need to add a blender? This is because the material coming out of the batching machine is unevenly distributed. If you granulate directly, the distribution of nutrients in fertilizer granules is uneven. Some elements are abundant, and some are even missing. So the mixer is an indispensable step. Our double shafts horizontal mixer uses a double-shaft design to make the material more evenly mixed. Generally, after the dynamic batching machine, it is transported to the mixing tank by the belt conveyor. Homogeneous agitation is carried out by means of helical blades mounted on double shafts. It is worth mentioning that the spiral blades on the double shafts rotate in opposite directions, so that the material is mixed more evenly. The stirring blade is made of high-strength wear-resistant material, which has a longer service life.
