Warmer Weather Increases Grain Storage Risks: CO2 Monitoring Recommended
US · Published May 5, 2026
• As temperatures rise in the spring, maintaining optimal storage conditions for grain becomes crucial to prevent spoilage. According to Bryan Reimer, product manager of GrainVue for GSI, monitoring carbon dioxide (CO2) levels in grain storage bins can serve as an early warning system for spoilage. Elevated CO2 levels often indicate the presence of spoilage before temperature changes are detectable. This is because the respiration of insects, mold, and fungi, which consume the grain, produces CO
• When moisture content exceeds recommended levels, it can lead to increased mold and insect activity, creating hot spots and raising temperatures within the bins. The GrainVue system by GSI not only monitors temperature and moisture but also tracks CO2 levels to help farmers take preventative actions before spoilage becomes a significant issue.

Why It's Important?

Experts recommend monitoring carbon dioxide (CO2) levels in grain bins as an early warning system because elevated CO2 often indicates spoilage before temperature changes are detectable. This is due to the respiration of insects, mold, and fungi consuming the grain.
