Harvest and Storage Issues

2010 - A hot and humid growing season produced good growth with projection of high yields. Flooding near final crop development created harvest issues on flood damaged crops, from mold and dust creating health concerns, and adulterated grain from flooding, and storage quality concerns. Another year of low test weight corn and disease complexes in corn and soybean required Quality Management topics for harvest and long term storage.

2009 - Two weather issues occured during the growing season impacting harvest quality and storage quality of grain. The first was hail damage in Northeast and Central Iowa during ear and pod development in corn and soybeans. The second issue was an overall cool growing season. Disease complexes increased and quality was reduced. Harvest drying requirements reached levels not seem for many years. Again quality management topics for harvest and long term storage of grain are topics presented.

2008 - The floods that ravaged Iowa brought concerns for moisture damaged grain in storage at the farm and elevator. Along with flooding, a cool growing season increased difficulty in crops reaching maturity and drying in the field. Disease complexes increased with flooding and slow field drying. Quality management topics for harvest and long term storage presented.

2006 - The erratic rainfall patterns across Iowa have affected both yield and quality for corn and soybeans. Because more corn is likely to be stored for local use through the entire crop year, attention to harvest and storage management details will be very important.

2005 - Weather patterns in 2005 caused aflatoxin levels to be significant in Eastern Iowa. An aflatoxin work shop was convened in April of 2006 to address questions; early warning models, harvest sample techniques, monitoring storage levels, producer, elevator, processor and government agency compliance responsibility to food safety.
