Abstract
For many farmers and agronomists, at this point in the growing season more thoughts move to determining realistic yield expectations. Making those yield estimates might be tough, especially for soybean, since both the corn and soybean crops are roughly halfway through grain fill. The daily rates of water and nitrogen uptake by the corn crop are decreasing and crop growth is at a slower rate than previous forecasts. Soybeans are still accumulating nitrogen and water at high rates (Tables 1 and 2). At this point, weather, insects, and diseases can still influence yields.
