A well-maintained fermentation bed is not only zero-emission, but also eco-friendly and beneficial for farmers. It reduces labor and increases productivity, helping farmers save time and make more profit. However, to ensure the success of a fermentation bed, there are several important parameters that need to be understood.
Bacteria play a crucial role in the process. Different types of bacteria come from various sources, and their composition and functions vary significantly. Some are single-function bacteria, such as just yeast or actinomycetes, while others are multi-functional, offering a broader range of benefits. Some bacteria are self-cultivated without specialized purification or rejuvenation, making them weak and less effective. Others may even fail to perform consistently, leading to poor results. To choose the right type, it's important to check the specifications, consult with the manufacturer or technical experts, and test small batches first. For example, Jinbao microbial fermentation additives are a natural compound bacteria developed in China. They consist of a mix of beneficial microorganisms such as bacteria, filamentous fungi, yeast, and actinomycetes. These are combined with advanced international technologies from the US, Japan, and South Korea, along with proprietary engineering processes. The product has undergone strict selection, multiple rounds of purification, and rejuvenation, ensuring strong oxygen-based decomposition and degradation capabilities. It helps in odor control and breaking down feces effectively.
Moisture levels are another critical factor. The ideal moisture content for a fermentation bed is around 65%. However, during long-term use, pig urine can affect the moisture balance. If the water level drops below the required threshold, the functional bacteria may become dormant. Therefore, when using a goldfish fermentation bed, it’s recommended not to add extra water unless necessary.
In terms of bedding material, sawdust is generally preferred. If straw is used instead, it should be placed in the lower layer, with a thickness of about 20 cm. The top layer must be made of dry sawdust. Proper drying of the sawdust is essential to maintain the effectiveness of the fermentation process. The total depth of the bedding should be around 50 cm for optimal performance.
