Grain storage
Aeration helps maintain grain quality and minimize storage losses. Managing stored grain with aeration includes:
- Understanding aeration
- How temperature and moisture impacts storability
- Airflow and equipment
- Managing aeration
- Monitoring equipment
Maintain the quality of your grain by following these steps:
- Sanitize the bin and surrounding area
- Clean and protect your grain
- Aerate and monitor the grain
Grain storage tips includes factors and formulas for crop drying, storage and handling.
- Moisture and shrink factors
- Recommended storage moisture
- Airflow recommendations
- Maximum storage times and equilibrium moisture contents
Proper airflow through grain reduces insect infestations and harmful fungi and bacterial growth. Selecting the right fans for drying, cooling and storage helps maintain grain quality:
- Airflow requirements
- Airflow resistance in crops
- Airflow resistance in bins and buildings
- Fan performance
Managing corn residue
Harvesting too much corn residue for feed, bedding or biofuel production can impact soil productivity. Learn how to sustainably harvest corn residue:
- How soil organic matter relates to soil carbon
- How much corn residue can you harvest
- Factors that affect harvest amount
- Costs of removing residue
- Corn cob removal
