How to make organic fertilizer from chicken manure of 100000 chickens

Chicken manure treatment and organic fertilizer production for 100000 chickens

In large-scale, automated, and intensive chicken farms, the treatment of chicken manure is an important and complex process. For a chicken farm with 100000 chickens, the daily production of chicken manure is enormous. Improper handling can not only cause environmental pollution, but also potentially lead to disease transmission. However, through scientific and rational processing, chicken manure can be transformed into high-quality organic fertilizer, providing valuable resources for agricultural production.

Characteristics and Problems of Chicken Manure

Chicken manure is a highly nutritious organic waste containing essential nutrients such as nitrogen, phosphorus, and potassium for plants. However, chicken manure also contains a large amount of pathogenic pathogens, insect eggs, and drug residues. Direct application can cause harm to plants such as burning roots and seedlings, and may even contaminate soil and water sources. In addition, chicken manure has a high water content, especially the manure of captive laying hens, which can reach around 80% water content and is difficult to directly accumulate and ferment.

Methods for treating chicken manure

For the treatment of chicken manure from 100000 chickens, the following methods can be adopted:

Natural drying method:

Sun chicken manure on cement or open ground, mixed with auxiliary materials such as wheat bran and rice bran for drying. This method is suitable for small-scale farmers, but for large-scale chicken farms, it is inefficient and occupies a large area.

High temperature drying method:

Using a dehydration dryer to quickly reduce the moisture content of chicken manure to below 13% at a high temperature of 500 ℃, suitable for large-scale breeding farms. This method has a high cost, but can effectively kill pathogens and insect eggs, and is easy to store and transport.

Fermentation treatment method:

Fermentation is one of the most commonly used methods for treating chicken manure, which converts harmful substances in chicken manure into harmless substances through the action of microorganisms, and produces abundant beneficial microorganisms and nutrients required by plants.

Mixing and Fermentation: Mix fresh chicken manure, crushed green feed, rice bran, etc. in a certain proportion, adjust the moisture content to about 60%, and seal for fermentation. Suitable for large chicken farms.

Mechanical fermentation: using a chicken manure regenerated feed fermentation machine for rapid fermentation, suitable for small and medium-sized chicken farms.

Aerobic fermentation: By using a turner to increase the amount of oxygen, fermentation efficiency and maturation success rate can be improved. Suitable for handling large amounts of chicken manure.

Silage method:

Mix chicken manure with green feed, grass feed, rice bran, etc., adjust the moisture content to around 60%, and seal and ferment for 30-45 days. This method is suitable for producing long-term stored feed or organic fertilizers.

Puffing method:

Dry fresh chicken manure to a moisture content of less than 30%, heat it in a puffing device to around 200 ℃, and quickly spray it out. This method can improve the organic matter digestion rate of chicken manure, but the equipment cost is relatively high.

The steps of making organic fertilizer from chicken manure

Mixing:

Mix chicken manure with straw, branches, mushroom residue and other auxiliary materials in a certain proportion, adjust the dry humidity and carbon nitrogen ratio. For chicken manure with high moisture content, auxiliary materials such as sawdust and bran can be added.

Fermentation:

Activate the bacterial strain using the “High Temperature Fermentation Agent for Poultry Manure” and mix it with chicken manure for heap fermentation. During the low temperature season, it is necessary to cover with film or grass for insulation. Regular flipping is required during the fermentation process to increase the amount of oxygen.

Crushing:

After fermentation, use a grinder to crush chicken manure organic fertilizer into powder form, which is convenient for crops to absorb and make into granules.

Ingredients and Mixing:

Add nutrients such as nitrogen, phosphorus, potassium, and microbial agents as needed, and stir evenly.

Granulation and drying:

Make powdered organic fertilizer into granules and dry it to remove excess moisture and prevent particle adhesion.

Cooling and packaging:

The dried granular organic fertilizer needs to be cooled and then packaged for sale or self use.

Advantages of Chicken Manure Organic Fertilizer

Nutritious: Chicken manure organic fertilizer contains abundant nutrients such as nitrogen, phosphorus, and potassium, making it a high-quality base fertilizer for crop cultivation.

Improving soil: Long term application of chicken manure organic fertilizer can improve soil structure, enhance soil fertility, and promote crop growth.

Environmental protection and safety: Chicken manure organic fertilizer that has been fully fermented has no odor, bacteria, or insect eggs, and is harmless to the environment and plants.

In summary, the chicken manure of 100000 chickens can be transformed into high-quality organic fertilizer through scientific and rational treatment, providing strong support for agricultural production. At the same time, this also conforms to the concepts of circular economy and sustainable development, achieving the maximization of resource utilization.
