The Iowa Soybean Association still need fields in some Iowa counties for the High Intensity Soybean Management trials and SuperCal SO4. If you're interested in participating in these and haven't already done so, please contact Matt Sweeney immediately (email@example.com or 515-334-1048).
In addition to these trials, there are several other trial opportunities available. For both corn and soybeans, they're continuing plant population and plant nutrition studies. Other possibilities for soybean trials include plant health, insect control, and seed treatment. For corn, we're continuing our usual nitrogen and manure management trials as well.
Growers interested in any of these can find more information at the On-Farm Network website. A convenient on-line trial sign-up form will be posted very soon. Look for it in the "What's New" section on the left side of the On-Farm Network home page.
