When your grain management system alerts you to elevated CO₂ levels, it’s an important early warning that spoilage may be occurring inside your bin. Studies show that spoiled grain, often caused by mold growth or insect activity, produces higher concentrations of CO₂, making CO₂ monitoring a valuable tool for protecting your stored grain.
But a CO₂ alert alone doesn’t tell the full story. To effectively address spoilage, it’s critical to know where in the bin the problem is happening and combine that with temperature and moisture data. This combined information gives you the recipe for the right next steps.
Pinpoint the Problem
Elevated CO₂ could indicate a localized hotspot or a broader issue. If the CO₂ is concentrated near the top or sides of the bin, it may signal pockets of spoiled grain that need to be removed by coring (removing a cylinder of grain from the center of the grain bin to reduce fine build up). On the other hand, if temperature and moisture levels suggest conditions favorable for spoilage, it could mean your aeration fans need to be turned on or adjusted to cool and dry the grain effectively.
Use Data to Guide Your Response
- Temperature readings help identify hotspots where grain may be warming and spoiling.
- Moisture levels show if the grain is too high in moisture and at risk for mold growth.
- CO₂ alerts reveal biological activity related to spoilage.
Together, these measurements enable you to make informed decisions: whether to run fans for aeration, perform a bin core to remove spoiled grain, or both.
Prevent Loss and Protect Your Grain
Ignoring CO₂ alerts can lead to rapid grain deterioration and economic loss. But by understanding how CO₂, temperature, and moisture data work together, you can take targeted action to preserve grain quality, reduce spoilage, and maintain market value.
Protect Your Investment
Your grain monitoring system is more than just a set of alarms. It is a powerful tool for grain management when used to its full potential. When you get a CO₂ alert, don’t stop there. Protect the grain you invested so much to yield by assuring you have the right data sets: moisture, temperature and CO₂ together deliver the full view of activity within your grain bin.
