Traditional organic fertilizer composting processes have long faced three major bottlenecks: long cycles (30-60 days), strong odor, and low levels of harmlessness. Pathogens, parasite eggs, antibiotics, and heavy metal residues in livestock and poultry manure not only threaten soil health but also become a major obstacle to the green development of the livestock industry. Now, with breakthroughs in rapid fermentation technology, this situation is being completely rewritten—a new process of 1-hour harmless treatment and half-hour high-temperature fermentation is guiding organic fertilizer production from “slow, smelly, and coarse” to “fast, good, and refined.”

Three Major Pain Points of Traditional Composting Traditional windrow or trough composting relies on natural heating, making it highly susceptible to seasonal and temperature fluctuations; fermentation may even completely stop in winter. The long maturation cycle of 1-2 months not only occupies a large amount of space but also involves the emission of malodorous gases such as ammonia and hydrogen sulfide. More importantly, the core temperature of natural compost often fails to maintain a stable above 55℃ for a sufficient duration, resulting in incomplete elimination of pathogens such as roundworm eggs and E. coli, and compromising the degree of harmlessness.Revolutionary Technology: 1-Hour Harmlessness Treatment + Half-Hour High-Temperature Fermentation

Represented by the closed-loop rapid fermentation organic fertilizer technology jointly developed by Shenyang Agricultural University and Shenyang Daqian Equipment Group Co., Ltd., this process achieves two core breakthroughs:

1-Hour Harmlessness Treatment: After the material enters the closed fermentation equipment, it is rapidly heated to 80–100℃ through a precise temperature control system, efficiently killing pathogenic microorganisms, parasite eggs, and weed seeds within one hour. This process completely solves the hidden danger of incomplete harmlessness in traditional composting.

Half-Hour High-Temperature Fermentation: After harmlessness treatment, the system automatically adjusts the temperature to the optimal fermentation range of 60–80℃, activating the activity of thermophilic compound microbial agents. Under forced stirring and oxygen supply conditions, organic matter decomposes rapidly, completing the main fermentation reaction in just half an hour.

After this treatment, the material is fermented in ton bags for 7-10 days to produce high-quality bio-organic fertilizer. Compared with traditional composting, the maturation cycle is shortened from 30 days to less than 1 day, increasing efficiency by more than 720 times.

Multiple Benefits of the Technology

The value of this technology lies not only in its speed. It achieves almost 100% harmlessness, effectively killing bacteria, viruses, and parasite eggs, and passivating heavy metal activity; fertilizer efficiency is significantly improved, with the product containing 3%-6% fulvic acid, three times that of traditional organic fertilizers, increasing crop yield by 15%-50%; it saves energy and reduces costs, saving more than 70% in space and labor, and reducing carbon emissions by more than 30%. Currently, this technology has been used to build 200,000-ton-level organic fertilizer production lines in many parts of the country, with a promotion area of ​​over 100,000 mu.

Conclusion

One hour of harmless treatment and half an hour of high-temperature fermentation—behind these figures lies a historic leap in the organic fertilizer industry from “relying on the weather for composting” to “industrialized intelligent manufacturing.” It not only significantly shortens the production cycle and reduces environmental pressure, but also provides a practical and feasible technical path for the resource utilization of livestock and poultry manure with higher fertilizer efficiency and lower carbon footprint.
