In 2013, growers are seeing a lot of variability in crop conditions both within fields and local areas and across the country. Depending on the location, growers faced challenges such as late-planted crops, drought stress conditions, and even excess moisture. Listen to John Gnadke's grain handling and storage tips for crops grown in 2013.

 
Tip 1.  Assess Fields & Make Equipment Adjustments  (01:28)

Inspect fields to determine variability, such as moisture conditions which will impact combine adjustments. Listen to John’s tips for sample size to ensure a good quality crop to dry and store as well as tips for combine adjustments.

Tip 4.  In-Bin Drying with Natural-Air & Low-Temperature Systems  (02:08)

John shares tips for in-bin drying, including both natural air and low temperature. It’s important all grain be level within 4-6 inches across the bin, otherwise low area will dry first and high area may never dry and start to spoil. He also shares tips and benefits for controllers in both situations.

Tip 5.  Know Your Airflow in Bins  (01:27)

John shares the importance of understanding airflow, regardless of bin size, in grain storage. Tips include proper temperature, fan timing and amount and how to avoid freezing grain.

Tip 6.  Airflow & Time Requirements to Adjust Grain Temperature  (02:19)

To highlight the importance of understanding airflow, John shares an example from his book. If you have 0.1 CFM of air, it requires approximately 200 hours to make a 10 degree temperature adjustment. If you have 1 CFM of air, it only takes 20 hours to make a 10 degree temperature difference.
