This integrated approach not only reduces waste disposal challenges but also creates a sustainable source of organic nutrition that enhances soil health and promotes long-term oil palm productivity, effectively closing the nutrient loop through innovative agricultural waste valorization.
The Potassium Connection
Oil palm (Elaeis guineensis) has a remarkable relationship with potassium – this essential nutrient drives its growth and fruit production. During development, oil palms accumulate significant potassium reserves in their tissues, particularly in fronds and fruit bunches. An average mature oil palm tree can contain 2-3 kg of potassium in its biomass, with empty fruit bunches (OPEFB) representing a concentrated source of this valuable nutrient.
From Waste to Resource
Traditionally viewed as milling waste, oil palm empty fruit bunches are now recognized as agricultural gold. When processed through composting, these organic materials transform into nutrient-rich fertilizer. The composting process typically takes 60-90 days, involving microbial breakdown that converts raw biomass into stable organic matter. This natural transformation creates a slow-release fertilizer that provides balanced nutrition to oil palms.
Soil Regeneration Benefits
Beyond potassium supplementation, OPEFB compost delivers multiple soil health benefits. It improves soil structure by increasing porosity and water retention capacity – particularly valuable in tropical soils prone to compaction and nutrient leaching. The organic matter enhances microbial diversity, creating a thriving soil ecosystem that supports plant health naturally. Regular application can increase soil organic matter by 15-25% over three years.

To maximize the performance of a windrow compost turner, a scientific and standardized operating process must be followed. The entire process of the windrow compost turner revolves around four key steps: raw material pretreatment, windrow accumulation, turning and fermentation, and determination of maturity.
Raw material pretreatment is fundamental. Collected organic materials must first be sorted to remove impurities such as metal and plastic. Livestock and poultry manure should be air-dried to a moisture content below 65%, and straw should be pulverized to 5-10 cm in length. The raw materials should then be mixed at a carbon-to-nitrogen ratio of 25-30:1. The carbon and nitrogen content can be adjusted by adding straw or manure, ultimately achieving a moisture content of 55%-60%. At this point, the material will clump when held and fall apart upon contact, achieving optimal fermentation conditions. Next, the pre-treated raw materials are stacked into trapezoidal stacks at the fermentation site. These stacks are typically 3-5 meters wide at the base, 1.5-2.5 meters wide at the top, and 1-1.8 meters high. The stack length can be adjusted flexibly based on the site and production volume. A 1.5-2 meter passageway is left between the stacks to facilitate equipment access and ventilation.
Turning and tossing is a key step in fermentation. After starting the windrow compost turner, the depth of the tossing mechanism is adjusted according to the height of the stack, ensuring that the tossing teeth penetrate 10-20 cm into the bottom of the material. The initial fermentation lasts 1-3 days, with the first tossing occurring when the material temperature reaches 50-60°C. The high-temperature period lasts 4-10 days. When the temperature rises to 60-70°C, the stacks are tossed every 1-2 days to kill harmful bacteria. The cooling period lasts 11-20 days. When the temperature drops to 40-50°C, the stacks are tossed every 2-3 days to promote humus formation. The entire fermentation cycle lasts 15-25 days.
Finally, the material is judged by maturity. When the temperature is close to room temperature, the color is dark brown, the texture is loose, and there is no odor or earthy smell, it is considered mature and can be sent to the next stage for processing.
With the advancement of green agriculture, “environmental protection and resource utilization” have become core priorities in fertilizer production. Double roller press granulators (fertilizer compaction machines), with their outstanding environmental performance and resource utilization, have become key equipment for green fertilizer processing.
The double roller press granulator offers significant technological advantages in improving fertilizer quality. The fertilizer granules formed through physical extrusion have uniform density and high hardness, making them less prone to breakage and clumping during transportation and storage. More importantly, after application to the soil, these granular fertilizers release nutrients at a steady rate, extending their effective life and reducing the loss of nutrients such as nitrogen, phosphorus, and potassium through rainwater erosion.
The double roller press granulator’s environmental value is also reflected in its raw material processing and energy consumption control. The double roller press granulator can directly process agricultural waste such as fermented livestock and poultry manure, composted straw, and fruit and vegetable residues, transforming “waste” into high-quality organic fertilizer and achieving resource recycling. The equipment also eliminates the need for high-temperature drying, reducing emissions from coal or gas combustion. Its enclosed conveying design effectively controls dust spillage, improving the production environment.
Furthermore, its operation and maintenance requirements are low. Its simple structure and clear procedures allow workers to master the process after a short training period. Routine maintenance requires only regular inspection of the squeeze rollers for wear and cleaning of the feed channel, significantly reducing operational costs for small and medium-sized fertilizer companies.
