The Key Role of Compost Turners in Organic Fertilizer Fermentation Composting Technology

Fermentation composting technology for organic fertilizer is the core link in biofertilizer production, converting organic wastes such as animal manure, crop straw, and agricultural by-products into nutrient-rich, harmless organic fertilizer through microbial decomposition. Among the equipments required for biofertilizer production, compost turners—integrated with fermentation composting turning technology—are indispensable core devices. They directly determine the efficiency of fermentation, the quality of compost, and the stability of the production process. From traditional windrow composting to advanced trough-type aerobic fermentation composting technology, different turner types such as large wheel compost turner and chain compost turner adapt to diverse production needs, becoming the backbone of efficient composting.

Aerobic fermentation is the mainstream of organic fertilizer composting, and its core demand is sufficient oxygen supply, uniform material mixing, and temperature control—all of which rely on fermentation composting turning technology. In the fermentation process, microorganisms need oxygen to decompose organic matter, and the accumulation of organic materials will easily lead to anaerobic environments, producing foul odors such as ammonia and hydrogen sulfide, and inhibiting beneficial microbial activity. Compost turners solve this problem by regularly turning the material, breaking the compacted layer, increasing the contact area between material and air, and supplementing oxygen to maintain the vigorous activity of aerobic microorganisms. At the same time, turning can evenly distribute the heat generated by fermentation, avoiding local overheating that kills beneficial bacteria or local low temperature that stalls decomposition.
