Corn yield potential estimates amidst a 'perfect storm'
As of July 2, corn may not have yet experienced yield reductions. Although yield estimates vary with locations based on July 8 model runs, if 2012 turns out as ‘median’ year, we may see yield reductions of 7 to 9 percent due to the weather forecast for the week of July 2-8. The best news is that yields at this time can still better the worst year experienced at each of the sites.
We must remember that not all of Iowa’s corn emerged on May 1 and will enter critical phases of crop development during better conditions. That, of course, remains to be seen.
We all know that many things can happen between now and harvest. If soil moisture conditions do not improve, yields will be reduced much more than these estimates. Meanwhile, let’s hope for cooler temperatures and rain!
