Participants in public corn and soybean yield trials and in other public research efforts or collaborations can have grain quality analysis done at the Iowa State University Grain Quality Lab, through the Iowa Grain Quality Initiative (IGQI). The corn quality factors included in the analysis are moisture, test weight protein, oil, starch, density, and a ranking of estimated ethanol yield. Soybean quality factors analyzed are moisture, protein, oil, and fiber (plus linolenic acid and saturated fats for modified fatty acid soybeans). This is an excellent way to compare end use quality for genetic trials and other field studies.
