How to grasp the proper moisture of the fermentation bed

Proper moisture management in a fermentation bed is crucial for its effectiveness, as it directly impacts the activity of beneficial microorganisms. The ideal moisture level for a Goldbeat fermentation bed is around 65%, which allows the bacterial cultures to function optimally. A simple way to check the moisture is by taking a handful of material—when squeezed, it should stick together but not drip water. If it's too wet or too dry, the microbial activity will be hindered. When the sawdust reaches 65% moisture, the microbes become active and start the fermentation process. But how can you accurately assess the moisture level of sawdust and other organic materials in practice? Let’s take a look at how the Goldfish fermentation bed system manages this: The moisture content of sawdust varies depending on its source. Fresh sawdust from trees like cypress, beech, or mixed woods may have higher moisture levels, typically estimated around 60%. On the other hand, dried or aged sawdust might only contain about 30% moisture. For a Goldfish fermentation bed covering 20 square meters with a 50 cm layer of sawdust, the total weight of the sawdust is approximately 1900 kg. At 30% moisture, that means about 570 kg of water is already present. Additionally, animal waste contributes significantly to the moisture content. Pig excrement, for example, contains roughly 60% water, and with 15-20 pigs in a 20 m² bed, the daily urine output can add up to around 60 kg of water—this is a major source of moisture and usually eliminates the need for additional watering. Other sources of moisture include leftover feed or rainwater, but these are minor and should be minimized by ensuring proper drainage and sheltering. Once the bed is properly set up, the natural moisture from the waste and sawdust should be sufficient. Over time, the moisture balance will stabilize, allowing the microbial community to thrive. However, if the bed becomes too wet, immediate action is needed: aerate the bed by creating holes, remove overly dry material, and add fresh dry sawdust to absorb excess moisture. It's important to note that fresh sawdust should not be sprayed with water. Only a small amount (5–10 cm deep) should be applied to older sawdust. In northern regions, where the air is drier, light spraying may be necessary, while in more humid areas, spraying is generally avoided unless the bed becomes extremely dry. This approach ensures optimal conditions for microbial activity without over-saturation.
