How To Produce Bio Organic Fertilizer With Organic Fertilizer Equipment?

Organic Fertilizer post

Fertilizers are not unfamiliar to farmers, and there are many types, such as organic fertilizers and bio-organic fertilizers. However, you may be unfamiliar with bio-organic fertilizers. What are the uses of bio-organic fertilizers? What equipment is needed in the production process? Are compost tanks, fertilizer granulators, and rotary drum dryers indispensable? As a professional organic fertilizer equipment manufacturer, we will give you a detailed answer. Let’s take a look.

Bio Organic Fertilizer Production

Bio-organic fertilizer refers to a compound of microorganisms with specific functions and organic materials that are mainly derived from animal and plant residues (such as livestock and poultry manure, crop straw, etc.) and have been harmlessly treated and decomposed. Bio-organic fertilizer is a type of microbial fertilizer. Organic waste is harmlessly treated and thoroughly decomposed, completely converted into organic fertilizer, and then some effective bacteria are added. The fertilizer is called bio-organic fertilizer. This fertilizer has the effects of both microbial fertilizer and organic fertilizer, and is an environmentally friendly fertilizer. Different microbial agents can be added according to soil conditions and application objects.

The main function of biofertilizer is to provide and increase the number of beneficial microorganisms in the soil. These microorganisms have a symbiotic relationship with plants, and they benefit each other. Microorganisms help decompose organic matter in the soil and colonize in the root zone or inside the plant, whether through seed treatment, spraying on the surface of the plant, or directly added to the soil. Microorganisms can also help plants resist pests and diseases, thereby further promoting healthy plant growth.

Biofertilizer Production Technology

Bio-organic fertilizer is an organic fertilizer suitable for agricultural use. Its main raw materials are organic waste and functional microorganisms. Therefore, in the process of bio-fertilizer manufacturing, you need to add microorganisms to organic fertilizers. In addition, the main production processes of bio-organic fertilizers include: material fermentation, fermented material crushing, adding live microorganisms (or bacteria) for fertilizers, mixing all materials, bio-organic fertilizer granulation, fertilizer screening and coating, etc. Therefore, the machines you will use include: compost tanks, fertilizer crushers, organic fertilzier mixers, fertilizer granulators, drum screening machines and coating machines, etc.

The production process of powdered bio-organic fertilizer is simple and easy to operate. Simply add specific microorganisms to the fermentation materials in prescribed proportions. During fermentation, use a mixer to blend the organic materials and microorganisms. Once thoroughly mixed, the mixture is dried and packaged.

Adding functional bacteria

Bio-organic fertilizer is a combination of organic fertilizer and functional bacteria. Bio-organic fertilizer is available in powdered and granular forms.

Adding functional bacteria to powdered bio-organic fertilizer: This process is relatively simple and has low cost. First, the fermented organic fertilizer and humic acid powder are mixed evenly in a certain proportion, and then a certain amount of functional bacteria agent is added. This process can use a horizontal mixer to mix the organic fertilizer and functional bacteria agent evenly. After mixing evenly, dry and package.

Adding functional bacteria to granular bio-organic fertilizer: In this case, functional bacteria can be added before, during or after granulation, or they can be mixed after granulation alone. If you choose to add functional bacteria after granulation, you can use a rotary coating machine to coat the fertilizer particles with functional bacteria. In addition, the strains and organic fertilizers can be granulated separately, and then mixed evenly with a fertilizer mixer.

Bio-organic fertilizer can be selected from compost fermentation. There are two types: powdered bio-organic fertilizer and granular bio-organic fertilizer.

Organic Fertilizer Equipment for Bio Organic Fertilizer Production

Compost turner

Production Capacity: 500-1600(m³/h)

Compost turner: Organic waste can be composted in windrows, and the cross-sectional shape of the compost can be trapezoidal or triangular. To prevent leakage, the compost is usually placed on a cement floor or in a concrete trough. Depending on the composting site, different compost turning equipment can be selected to adjust the temperature, gas content and moisture. There are self propelled compost turner and hydraulic compost turner for chose.

Organic Fertilizer Fermentation Tank

Production Capacity: 4~5m³/day

Organic fertilizer fermentation tanks: During the fermentation process, the compost will produce some odors and pollute the surrounding air. If you want to prevent secondary pollution, you can use fermentation tanks for composting. In addition, organic fertilizer fermentation tanks have automatic control of temperature, humidity and air content, which can provide a stable and comfortable environment for microbial activities.

The production process of powdered bio-organic fertilizer is simple and easy to operate. Simply add specific microorganisms to the fermentation materials in prescribed proportions. During fermentation, use a mixer to blend the organic materials and microorganisms. Once thoroughly mixed, the mixture is dried and packaged.

Granulation is the key process in the production of bio-organic fertilizer. Different from the production of organic fertilizer granules, specific functional microorganisms need to be added during the granulation process. You can choose to add them during the granulation process or after granulation. We have four types of pellet machines for you to choose from according to your needs: rotary drum granulator, disc granulator, flat die pellet mill, ring die pellet mill.

Granulation is a key step in the production of bio-organic fertilizer. According to the above steps, you can add functional bacteria before granulation; you can also add bacteria during granulation. We have rotary drum granulators and disc granulators for you to choose. In addition, these machines all use wet granulation, so you can add functional bacteria with water in the granulator to achieve the compounding of organic fertilizer and bacteria.

Considerations after Granulation of Bio-Organic Fertilizer

After the organic fertilizer is pelletized, several crucial steps must be carefully followed to ensure the quality and effectiveness of the final product.

Firstly, depending on whether microorganisms are added during or after the pelletization process, subsequent procedures vary. If microorganisms are added during pelletization, it is essential to use a rotary dryer for post-pelletization drying. During this process, careful temperature control is necessary to avoid high temperatures that could affect the beneficial microorganisms’ activity and functionality.

Alternatively, if microorganisms are added after pelletization, a rotary coating machine should be used. This equipment helps evenly coat microorganisms onto the fertilizer pellets, ensuring firm attachment and effective action. Following the addition of microorganisms, it is recommended to use ABC Machinery’s rotary screening machine to sieve the organic fertilizer. This step helps remove oversized or undersized particles, ensuring product uniformity and quality.

Additionally, to enhance production line efficiency and reduce labor costs, introducing ABC Machinery’s single or dual bucket automatic packaging scales is advised. These devices can accurately and automatically package fertilizers, simplifying the final stages of production.


In conclusion, meticulous attention to these post-pelletization steps—drying, coating, screening, and packaging—is crucial for maintaining and enhancing the quality and effectiveness of organic fertilizers. By effectively utilizing organic fertilizer equipment and working with ABC Machinery, agricultural enterprises can simplify the granulation process and achieve efficient production through advanced organic fertilizer technology.
