What are the raw materials for bio-fertilizers?

Raw Material Composition of Biofertilizers

Biofertilizers, also known as microbial fertilizers, consist of three core components: functional microbial strains, organic carriers, and auxiliary ingredients. This unique combination ensures that the fertilizers not only provide nutrients to plants but also improve soil environment and promote crop growth through microbial activities.

Functional Microbial Strains

As the “active heart” of biofertilizers, functional microbial strains determine the specific efficacy of the fertilizer. Common strains include nitrogen-fixing microorganisms like Azotobacter chroococcum, which convert atmospheric nitrogen into plant-absorbable forms; phosphorus and potassium solubilizing microorganisms like Bacillus subtilis, which release fixed nutrients in soil; as well as growth-promoting and disease-resistant microorganisms that enhance plant health by secreting growth hormones or suppressing pathogens.

Organic Carriers

Organic carriers account for 80%-95% of biofertilizers, providing the substrate for microbial survival and reproduction. Ideal carriers need to be loose and breathable, with good water and fertilizer retention properties, while being rich in organic matter. Commonly used carriers include agricultural waste such as decomposed straw and livestock manure, industrial by-products like humic acid and lignite, as well as other materials such as peat soil and plant ash.

Industrial Production Process

The industrial production of biofertilizers is a precise and complex process, with the core objective of ensuring functional strains stably survive and maintain activity within the carriers.

Pretreatment Stage

Production begins with raw material pretreatment. Organic carriers require crushing, decomposition, or sterilization treatment to eliminate harmful microorganisms and create a suitable living environment for functional strains. Meanwhile, functional strains undergo large-scale cultivation through a three-stage amplification process, gradually scaling up from laboratory flask culture to industrial-scale fermenter production.

Mixing and Forming

The amplified bacterial solution is uniformly combined with pretreated carriers in mixing equipment. This step requires precise control of bacterial solution ratio and mixing time to ensure each carrier particle fully adsorbs functional strains. Subsequently, the mixture forms 2-4 millimeter granules through granulation equipment and undergoes drying under strict low-temperature conditions to protect strain activity.

Quality Control and Packaging

Dried granules require strict quality testing, including indicators such as effective viable bacteria count, contamination rate, and heavy metal content. Qualified products are packaged using special breathable packaging materials and stored in cool, ventilated environments to maximize product shelf life.

Key Production Control Points

The success of biofertilizer production depends on the control of multiple key factors. Temperature management is particularly important, as the temperature must not exceed 45°C throughout the production process to avoid damaging strain activity. Moisture control is equally crucial, with carrier moisture needing to be maintained within the suitable range of 40%-50%. Additionally, production environment cleanliness and raw material quality directly affect the final product’s effectiveness.

Biofertilizers represent an important trend in modern agriculture’s move toward greater sustainability. By converting agricultural waste into valuable resources while reducing dependence on chemical fertilizers, biofertilizers not only improve agricultural production efficiency but also make positive contributions to environmental protection.

Integrating Biofertilizer Production into Modern Organic Fertilizer Manufacturing

The sophisticated production process for biofertilizers represents a specialized segment within the broader organic fertilizer manufacturing industry. While traditional organic fertilizer production line systems focus primarily on nutrient content and physical properties, bio organic fertilizer production line configurations must additionally preserve microbial viability throughout processing. This requires specialized equipment and careful process control, particularly during the crucial organic fertilizer fermentation stage where temperature management is essential for maintaining strain activity.

Granulation technology plays a particularly important role in biofertilizer production, with equipment selection directly impacting microbial survival rates. The standard organic fertilizer granulator must be adapted for low-temperature operation, while innovative solutions like the new type organic fertilizer granulator and new type two in one organic fertilizer granulator offer integrated approaches that minimize thermal stress on microorganisms. These specialized fertilizer granulator systems represent significant advancements in biofertilizer production technology, enabling the creation of stable, granular products that maintain high microbial counts.

Binderless pellet formation process for chicken manure organic fertilizer

Due to its “dry granulation” characteristics, the fertilizer compaction machine eliminates the need for large amounts of binders, maximizing the active organic matter and nutrients in the manure. It is an ideal machine for granulating chicken manure organic fertilizer.

Mature chicken manure must first be crushed and screened to break up any remaining lumps and ensure a uniform particle size (typically 60-80 mesh). This prevents large particles or impurities from affecting the extrusion process. The moisture content must also be strictly controlled, maintaining it between 45% and 50%. Excessive moisture can cause sticking to the rollers during extrusion, while excessive dryness can hinder agglomeration and formation. If the crude fiber content of the chicken manure is too high, a small amount of humus or wood ash can be added to improve the material’s plasticity and enhance pellet strength.

The mixed material is conveyed through a conveyor to the fertilizer compaction machine. The core working components of the machine (a twin-roller or spiral structure) use high pressure to compress the loose material into a continuous sheet or strip intermediate. This intermediate is then processed through crushing and spheronization to form pellets of uniform size. The formed granules are first screened and graded. Unqualified fine powder or large lumps are returned to the crushing stage for reprocessing. Qualified granules enter a cooling facility and are packaged after cooling to room temperature.

Chicken manure organic fertilizer processed by the fertilizer compaction machine has high granular strength and is less prone to moisture absorption and agglomeration. This preserves the natural nutrients of the chicken manure while solving the inconvenience of handling bulk materials. This is a high-quality processing solution that balances nutrient retention and practicality.
