Dr. Charles Hurburgh, ISU grain quality extension specialist and Landus Cooperative member in Calhoun County offered Landus Cooperative members some insights and tips on managing the quality of on-farm stored grain. We interviewed Dr. Hurburgh on Wed. Sept. 18th. Listen to his full interview in our podcast starting at the 15-minute mark.
In summary, Hurburgh expects the following for harvest:
- FM. Hurburgh expects higher foreign matter content in soybeans. The late planting season meant a later date for soybeans to reach canopy which allowed for more than usual weed escapes. We expect to see the impact on soybean quality.
- Variability. Variability is difficult to manage in storage, so we should try to minimize on-farm storage variability while we are in the field. For example, if there’s a place where you re-planted and the moisture will be higher there, wait on that section. Give it the time it needs to mature and dry down and come back to get it later. Test each hybrid and get test weight on each hybrid so you know what might store better than others.
- Quickly Dry. With the variability in the field, we want to get our grain dry as quickly as possible. Dryers are designed to lower the moisture of all your stored grain, not reduce the variability. Watch the dew point; low dew points help cool the grain and allow you to store it longer.
Dr. Hurburgh is also the professor-in-charge of the Grain Quality Laboratory at Iowa State University, which provides analysis of the chemical and physical properties of grain, primarily corn and soybeans. This lab is recognized as a world leader in basic measurement science. Dr. Hurburgh's research interests include the physical and chemical properties of biological materials, chemical and electronic instrumentation, near-infrared reflectance analysis and sensors, chemometrics, metrology, and statistics of very large databases.
