What is the optimum temperature of the microorganism in the fertilizer starter?
Fertilizer fermentation aids contain various functional microorganisms, such as actinomycetes, yeasts, bacillus, and filamentous fungi. These are living organisms that require specific environmental conditions to grow and reproduce effectively. Each type of microorganism has an optimal temperature range for activity. For example, anaerobic species typically thrive between 25–35°C, while aerobic bacteria prefer 40–50°C, and thermophilic microbes work best in the 60–65°C range. Jinbao Organic Fertilizer is formulated with specialized microorganisms that can adapt to a wide range of temperatures, making it suitable for different fermentation scenarios.
To ensure efficient fermentation, it's crucial to maintain the right temperature for each microbial group. The ideal temperature range for most microorganisms in general fertilizer fermentation aids usually falls between 20–60°C. If the temperature is too high or too low, it can significantly impact the fermentation process. In colder seasons, when ambient temperatures drop, it’s important to take measures to raise the initial fermentation temperature. This can include using insulating materials, increasing the size of the compost pile to retain heat, or even using external heating sources if necessary.
However, excessively high temperatures—above 70–75°C—can be harmful. At these levels, many microorganisms that function at lower temperatures may die off, and those in the high-temperature zone may become less active. This can lead to prolonged fermentation times, reduced efficiency, and increased labor costs. When this happens, it’s essential to turn the pile regularly to improve aeration, reduce internal heat, and prevent nutrient loss.
On the other hand, if the ambient temperature is too low—such as around 10°C—the activity of the functional microorganisms in the fermentation aid decreases. When the temperature drops below 5°C, these microbes essentially go into dormancy and stop reproducing. To avoid this, it’s necessary to artificially raise the temperature. Otherwise, the effectiveness of the fermentation aid will be greatly reduced, leading to economic losses and inefficiencies.
Therefore, most users should aim to maintain an ambient temperature above 15°C for optimal performance. Monitoring and adjusting temperature during the fermentation process is key to ensuring the success of the composting or organic fertilizer production. By paying attention to these factors, users can maximize the benefits of their fertilizer fermentation aids and achieve better results.
