FAQ

Recommended Moisture Contents:

• Corn: 15.5% for short-term, 13% for long-term
• Wheat: 12-14%
• Soybeans: 13% for short-term, 11% for long-term
• Rice: 12-14%

For Grain Cooling:

• Minimum: 0.1 CFM/bushel
• Recommended: 0.15-0.2 CFM/bushel

For Grain Drying:

• Natural air drying: 0.5-1.0 CFM/bushel
• Heated air drying: 1.0-2.0 CFM/bushel

• Summer storage: Below 20°C
• Winter storage: Below 5°C for long-term
• Optimal range: 10-15°C for extended storage

Why it matters: Most insects inactive below 15°C; mold growth slowed below 15°C

Problem Areas: Under roof, grain surface, bin walls

Prevention: Aeration to equalize temperature, roof ventilation, temperature monitoring

• Temperature control: Keep grain below 15°C
• Moisture management: Maintain proper moisture content
• Sanitation: Clean bins before new grain storage
• Monitoring: Trap monitoring, regular sampling

Visual: Discoloration, mold growth, caking

Olfactory: Musty odor, sour smell

Temperature: Temperature rise, hot spots

• Similar moisture grains can be stored together
• High-value grains should be separate
• GMO/non-GMO requires complete separation
• Organic/conventional cannot be mixed

• Corn: 6-12 months at 14% moisture
• Wheat: 12-24 months at 13% moisture
• Soybeans: 6-12 months at 12% moisture

• Above 30°C: Rapid insect reproduction
• Below 15°C: Insect reproduction minimal
• Below 5°C: Insects dormant

• Maintain proper moisture and temperature
• Monitor for insects and mold
• Regular grain rotation
• Temperature cables for continuous monitoring
