Complete Guide to Organic Fertilizer Composting and Fermentation

by organic fertilizer production line

Compost fermentation is a natural process that uses microorganisms to decompose organic matter. By scientifically controlling the four key elements – carbon-nitrogen ratio, moisture, temperature, and oxygen – agricultural waste can be transformed into high-quality organic fertilizer. This process is not only environmentally friendly but also provides rich nutrients for the soil.

Material Preparation and Ratio

Successful composting begins with the correct material ratio. Carbon sources such as straw, sawdust, and fallen leaves should account for 70%-80% of the total volume, and these materials need to be crushed to 5-10 cm for better decomposition. Nitrogen sources include livestock manure and kitchen waste, comprising 20%-30% of the mixture.

Key Tip: The carbon-nitrogen ratio should be maintained between 25:1 and 30:1. Imbalanced ratios can lead to slow decomposition (excess carbon) or odor problems (excess nitrogen).

Pile Construction Methods and Techniques

When building the compost pile, recommended dimensions are 1.5-2 meters wide at the base and 1-1.2 meters high. Use a layered approach: first spread 15-20 cm of carbon materials, then add 5-10 cm of nitrogen materials, and finally sprinkle with conditioners. Repeat this process until reaching the desired height.

Four Stages of the Fermentation Process

Heating Phase (0-7 days)

Microorganisms begin rapid reproduction, raising the pile temperature from ambient to 50°C. This stage mainly decomposes easily degradable organic matter and doesn’t require turning.

High-temperature Phase (7-21 days)

Temperatures rise to 55-70°C, with thermophilic bacteria becoming active and effectively killing insect eggs and pathogens. Turn the pile every 3-5 days to ensure adequate oxygen supply.

Cooling Phase (21-35 days)

Temperatures gradually decrease below 40°C, and mesophilic bacteria begin decomposing difficult-to-break cellulose materials. Turning frequency can be reduced to once every 7-10 days.

Maturation Phase (After 35 days)

The pile temperature drops to ambient levels, materials turn dark brown, become loose in texture, and emit an earthy fragrance. The compost is now fully matured.

Post-processing and Storage

Following the crucial organic fertilizer fermentation process, mature compost undergoes essential post-processing within a complete organic fertilizer production line. The material is first screened to remove undecomposed fragments, a standard procedure in the bio organic fertilizer production line that ensures product uniformity.

The entire fermentation composting technology for organic fertilizer relies on specialized equipment like the large wheel compost turner and chain compost turner for efficient aeration. These compost fertilizer machine units, including the versatile windrow machine, are fundamental among the equipments required for biofertilizer production.

For granulated products, the process may incorporate a disc granulation production line featuring a specialized fertilizer granulator, followed by a drum organic fertilizer dryer for moisture control. Each fertilizer production machine in this sophisticated fertilizer making machine ecosystem contributes to transforming compost into market-ready products.

The final product should be stored in dry, ventilated facilities for up to six months. By mastering organic fertilizer fermentation and utilizing advanced fermentation composting technology for organic fertilizer, we effectively convert organic waste into valuable resources, supporting sustainable agriculture through optimized production systems.

Horizontal crushers: A reliable helper for fertilizer companies to reduce energy consumption

by organic fertilizer production line

Electricity costs can account for 15%-20% of fertilizer production costs. As a high-energy-consuming component, controlling the energy consumption of pulverizing equipment directly impacts a company’s cost-saving efforts. Many companies overlook the potential for energy optimization in horizontal crushers. In fact, through structural and operational logic design, these pulverizers can be a reliable tool for reducing energy consumption.

1.Load Adaptation of Variable Frequency Motors

Traditional pulverizing equipment often uses fixed-speed motors, operating at full capacity regardless of the hardness or moisture content of the raw material. This results in a “big horse pulling a small cart” pattern of energy waste. Horizontal crushers equipped with variable frequency motors, however, can adjust their speed based on raw material characteristics, reducing motor energy consumption by an average of 15%-20%.

2.Resistance Optimization of Blade Structure

The optimized horizontal crusher reduces air resistance. The staggered blade arrangement allows the material to enter the shear zone more smoothly, avoiding ineffective impacts. This allows more electrical energy to be converted into crushing kinetic energy rather than resistance losses, reducing energy consumption by an additional 8%-10%.

3.Load balancing reduces energy consumption fluctuations

Uneven feeding of the crusher can cause the motor load to fluctuate (a sudden surge in current during an overload), increasing overall energy consumption over time. A horizontal crusher can be equipped with an “intelligent feed controller” that monitors the motor’s load current in real time and automatically adjusts the feed speed to avoid additional energy consumption caused by load fluctuations.

Double roller press granulators enhance the adaptability of organic fertilizer production lines

by organic fertilizer production line

In the trend of upgrading organic fertilizer production lines towards “high efficiency, flexibility, and ecology,” double roller press granulators, with their unique physical shaping logic, have become a “core node” in the production line, adaptable to diverse raw materials.

The core of an organic fertilizer production line is the transformation of organic waste into standardized fertilizer, and the granulation process is crucial in determining the fertilizer’s form and usability. Double roller press granulators precisely address this need, using only the high pressure generated by two relatively rotating rollers to extrude loose organic powder into granules. This dry material forming process is perfectly suited for organic raw materials such as straw and livestock manure, which have low moisture content and insufficient viscosity after fermentation.

In the entire organic fertilizer production line, the double roller press granulator plays a “flexible connecting” role. It can handle organic substrates of different textures after previous crushing. Whether it’s fermented straw with high coarse fiber content or fine livestock manure powder, it can achieve efficient granulation through pressure shaping. Meanwhile, its simple structure allows for easy integration with subsequent stages of the production line, such as screening, cooling, and packaging, without the need for complex process adjustments, significantly shortening the production cycle.

The double roller press granulator gives organic fertilizer production lines a greater ecological advantage: the absence of chemical additives ensures the purity of the organic fertilizer, dry material forming reduces energy consumption and pollution, and the formed granules have moderate hardness, facilitating storage and transportation while allowing for the slow release of nutrients after application. This dual advantage of “adaptability + ecological benefits” allows organic fertilizer production lines to better handle diverse organic waste.

Bio-organic fertilizer production line: Enabling agricultural waste to “Flow” through an ecological closed loop

by organic fertilizer production line

In the development of green agriculture, the bio-organic fertilizer production line is not merely a “fertilizer-making device,” but a crucial link connecting “agricultural waste – organic nutrients – healthy soil.”

The first step of the production line is the “inclusive” treatment of raw materials. Whether it’s livestock manure, crop straw after harvesting, or mushroom residue from edible fungi cultivation, these wastes, varying greatly in form and moisture content, can all be accepted by the production line. This adaptability to “diverse wastes” is key to the production line’s solution to agricultural environmental protection issues.

The fermentation stage is the “core hub” of the bio-organic fertilizer production line. Unlike traditional composting that relies on “weather conditions,” the production line precisely regulates the fermentation environment through temperature and oxygen supply systems. The entire process avoids odor pollution from waste fermentation and allows the materials to continuously decompose at a high temperature of 55-65℃, thoroughly killing insect eggs and pathogens.

In the finished product processing stage, the production line demonstrates even greater “flexibility and adaptability.” Depending on planting needs, it can process the decomposed material into powder or granules. Simultaneously, the production line controls the moisture content of the finished product through drying and cooling processes, ensuring that the organic fertilizer does not clump during storage and transportation, and that nutrients are not lost.

Today, the value of the bio-organic fertilizer production line has long surpassed the act of “fertilizer production” itself. It transforms agricultural waste from an “environmental burden” into “soil nutrients,” truly completing an ecological closed loop of “resource-production-reuse.”

NPK fertilizer production line: Targeting precise nutrients from diverse materials

by organic fertilizer production line

NPK fertilizers can be formulated with nitrogen, phosphorus, and potassium nutrients according to crop needs, becoming “customized” fertilization solutions for agriculture. The core capability of this NPK fertilizer production line lies in its flexible handling of diverse materials.

First and foremost is the “difference” in the form of raw materials. The nitrogen source for NPK may be granular urea or powdered ammonium chloride, the phosphorus source is often lumpy monoammonium phosphate, and the potassium source is mostly free-flowing potassium chloride granules. The production line must first use crushing and grinding processes to grind the lumpy phosphorus source into fine powder, and then adjust the different forms of nitrogen and potassium raw materials into a homogeneous intermediate to avoid “particle clumping and powder settling” during subsequent mixing, ensuring that each nutrient is evenly distributed.

Secondly, there are the “special” physical and chemical properties of the materials. Some nitrogen sources tend to clump after absorbing moisture; for example, urea will harden into lumps when damp. Phosphorus sources have lower corrosivity, while potassium sources need to be protected from high temperatures to prevent nutrient loss. This requires the NPK fertilizer production line to “prescribe the right medicine for the right disease” during processing.

Finally, there is the “flexibility” of the material ratio. Different crops require different NPK ratios; for example, rice needs high nitrogen and low potassium, while fruits and vegetables need high potassium and low phosphorus. The production line needs to use a precise metering system to adjust the input of each raw material according to the formula at any time during material processing. In short, the NPK fertilizer production line“Strength” lies in the meticulous handling of diverse materials.

Why do horizontal crushers require special adaptations for bio-fertilizer production?

by organic fertilizer production line

The core difference between bio-fertilizer production and conventional organic fertilizer and compound fertilizer production lies in the need to preserve the activity of the inoculant. Furthermore, the raw materials often consist of specialized materials such as fungus residue, traditional Chinese medicine residue, and fermented straw. This places special demands on grinding equipment: low temperature, pollution prevention, and precise particle size. Through targeted modifications, horizontal crushers have become the ideal choice for bio-fertilizer production.

1.Low-temperature crushing preserves inoculant activity

The functional bacteria in bio-fertilizer (such as Bacillus subtilis and phosphate-solubilizing bacteria) are not tolerant to high temperatures. Excessive frictional heat (above 45℃) generated during the grinding process can inactivate the bacteria. High-quality horizontal crushers optimize the impeller speed (to avoid excessive friction) and some are equipped with a “water-cooling jacket” to circulate cold water to remove heat from the chamber walls, maximizing inoculant activity.

2.Anti-residue design prevents cross-contamination

Bio-fertilizer production often requires switching between different inoculant formulations. If residual material from previous batches remains in the equipment, bacterial strains can mix. The horizontal crusher’s “fully open cleaning structure” solves this problem. The grinding chamber door can be fully opened, and the smooth, corner-free interior allows for quick cleaning without disassembling core components, reducing the risk of cross-contamination.

3.Precise Particle Size for Microbial Agent Mixing

Bio-fertilizer production requires uniform particle size (typically 1-3mm) after grinding. Uneven particle size results in incomplete mixing of the microbial agent and raw material, impacting fertilizer efficiency. The horizontal crusher can precisely control particle size deviation within ±0.5mm, providing a high-quality raw material foundation for subsequent microbial agent inoculation and mixing.

Chain crushers: Why have they become the “main force” in organic fertilizer raw material crushing?

by organic fertilizer production line

In the fertilizer production process, raw material crushing is a critical step in determining the quality of the final product. This is especially true for organic fertilizer production, which often processes a variety of materials such as straw, cake meal, and fermented livestock and poultry manure. Chain crushers, due to their unique advantages, have become a common equipment in the industry.

Unlike traditional crushing equipment, the core working component of a chain crusher is a high-strength chain. When the equipment is started, the motor drives the drum to rotate at high speed, and the chain on the drum moves in a circular motion. The impact and shear forces generated by the high-speed chain tear and crush the fertilizer raw materials entering the crushing chamber.

For high-fiber materials such as straw, the chain can penetrate deep into the fibers and sever the structure. For hard materials such as cake meal, the impact force of the chain effectively breaks up clumps, avoiding the problem of material jamming that traditional equipment often encounters.

More importantly, chain crusher can adapt to the diverse raw material characteristics of the fertilizer industry. Whether it is wet materials with a moisture content of 15%-25% or dry block raw materials, stable crushing can be achieved, and the particle size of the crushed materials is uniform, without the need for secondary screening, and can directly meet the requirements of subsequent granulation and mixing processes, greatly improving the production efficiency of organic fertilizers.

Large wheel compost turning machines empower efficient operation of organic fertilizer production equipment

by organic fertilizer production line

In the ecological chain of organic fertilizer production equipment, large wheel compost turning machines, with their core advantages of “wide coverage and deep turning,” have become the “efficiency leader” in the fermentation process.

The design of large wheel compost turning machines is tailored to the needs of large-scale production. Its core large disc is equipped with multiple sets of high-strength turning teeth. During operation, the disc rotates at a uniform speed, penetrating deep into the thick pile of organic materials, turning and breaking up mixed raw materials such as straw and livestock manure from the bottom up. This turning method not only covers a wide area, processing large areas of the pile at once, but also allows the material to fully contact with air, providing sufficient oxygen for microbial composting and reducing the odor and harmful substances produced by anaerobic fermentation at the source.

As a crucial link in organic fertilizer production equipment, it precisely controls the quality of composting. Organic material composting requires a stable high-temperature environment. Through regular turning, the large wheel compost turning machine can dissipate excess heat from the center of the pile and allow material from low-temperature areas to enter high-temperature areas, ensuring consistent composting progress throughout the entire pile.

In the entire organic fertilizer production process, the large wheel compost turning machine plays a crucial role: it receives the results of the previous raw material mixing process and efficiently decomposes the material to produce a loose, nutrient-uniform substrate, reducing obstacles for subsequent crushing and granulation processes.

From the harmless treatment of organic waste to the large-scale production of high-quality organic fertilizer, the large wheel compost turning machine makes the operation of organic fertilizer production equipment more efficient and stable.
