The excellent matrix is formed through full fermentation.
Fermentation is the key technology in creating a nutrient-rich soil matrix, and there are several methods used in the process. The traditional stacking method is commonly applied during composting, with one method being aerobic fermentation and the other anaerobic. Another technique is pyrolysis, often used for waste treatment. Fermentation tanks are mainly used for odor control. However, the most widely adopted method is rapid fermentation, also known as bacterial-assisted fermentation—such as the use of products like Golden Baby, which act as fermentation enhancers. Considering factors like time, temperature, efficiency, and cost, bacterial-assisted fermentation is one of the most promising techniques for organic media, especially for large-scale or commercial production. The strains used include imported products from Japan and South Korea, as well as domestic brands like Kinbara, which are well recognized in the industry.
Substrate fermentation involves a series of complex biochemical reactions, leading to significant changes in various indicators. The ideal carbon-to-nitrogen (C/N) ratio during fermentation is typically between 20:1 and 30:1. However, many raw materials like bark, sawdust, and husks often have a high C/N ratio at the start, sometimes exceeding 150. Adjustments are necessary to achieve the optimal balance. Moisture content should be maintained at around 60% to 70%. It's also important to create an aerobic environment for microorganisms by using aeration and turning the material regularly.
The temperature during fermentation generally follows a pattern: starting low, rising to a high peak, then dropping to a moderate level, and finally decreasing again. At the beginning, the pH is slightly acidic, but it gradually increases as fermentation progresses. The EC (electroconductivity) value rises during the process and then slowly declines as the fermentation comes to an end. Microbial populations also change throughout the process, starting with mesophilic bacteria, followed by high-temperature cellulose-degrading bacteria such as Trichoderma, then actinomycetes, and finally fungi.
To produce a high-quality fermentation substrate, it's essential to choose reliable fermentation agents, such as the Goldfish microbial agent. Proper operation is equally important to ensure good results. Different fermentation strains can significantly affect the final outcome and may vary in cost by several times. Therefore, selecting the right strain and following the correct procedure is crucial for successful and efficient fermentation.
