aginsightcenter.com Variable growing conditions can create grain quality challenges and safety risks during harvest. From excess moisture to drought-stressed crops and high yields, these conditions require careful management to protect crops, maintain quality and ensure worker safety.

Adapting harvest and storage practices is key to avoiding costly losses and maintaining safe operations during the busy harvest season.

Managing excess crop moisture at harvest

Periods of rain or late irrigation can lead to excess moisture in grain. High-moisture grain can cause bridging and crusting in storage, disrupting flow and creating serious safety hazards for workers. Prolonged drying times can also increase the risk of grain dryer fires, particularly when dust and residue accumulate and restrict airflow.

To help manage these on-farm hazards:

• Clean grain dryers regularly, especially during high-moisture periods.

• Establish fire watch protocols and assign staff to monitor dryer operations.

• Post emergency contacts and review response plans with local fire departments.

• Monitor bins frequently for temperature changes, odors or signs of heating.

• Use temperature and moisture monitoring systems where available.

Handling and storing drought-damaged crops

Drought conditions can result in lightweight kernels, increased foreign material and structural changes in grain. These factors can reduce grain quality and increase the risk of mold growth and mycotoxin development in storage.

To help manage drought-damaged crops:

• Adjust combine settings, including ground and rotor speed, to reduce kernel damage.

• Fine-tune cleaning systems to handle increased chaff and lighter material.

• Test grain for mycotoxins to identify hidden quality issues early.

• Store damaged grain separately and prioritize it for shorter-term storage.

• Ensure adequate aeration, and monitor bins more frequently for temperature and moisture changes.

Avoiding grain storage risks when time is tight

Harvest can put pressure on storage capacity, especially during high-yield years. Rushing to move grain can increase the temptation to use marginal storage options or bypass safety procedures.

Temporary storage methods such as ground piles can be effective when properly managed but require careful site selection and monitoring. Poor drainage or unstable ground conditions can lead to spoilage and handling issues. High volumes of grain and inconsistent quality can also increase the risk of clogs, equipment strain and unsafe bin entry situations.

To reduce storage risks:

• Select well-drained, stable sites for any temporary storage.

• Use proper ground pile practices, including appropriate covers and ventilation.

• Monitor grain condition regularly during storage and transfer.

• Establish checkpoints for moisture, temperature and visual quality.

• Address grain flow issues promptly to avoid buildup or plugging.

• Follow grain bin safety practices, including never entering bins alone and using proper safety equipment.

• Implement lockout/tagout procedures when servicing equipment.
