Corn crop stressed by heat wave, bulk of crop enters pollination
In Kansas, 71 percent of the top soil moisture was short to very short, according to the NASS office in Topeka.
For Illinois, the downgrade in corn as well as soybeans was due to drought stress, said Emerson Nafziger, University of Illinois Extension agronomist.
Nafziger said Illinois corn was in the midst of pollinating but the late planted corn would likely not complete pollination until the first week in August.
"The most stressed crop was planted late and hasn't tasseled yet. The root systems really aren't very good on the late planted corn," he added. "Temperatures are moderating which will help."
In Ohio, warmer weather helped farmers push along on wheat harvest - now nearly even with the five-year pace - as well as give corn a boost. USDA rated 77 percent of the corn crop good to excellent, up from 74 percent a week ago.
"Corn has recovered well after flooding and winds from last week, and condition looks good as some is even beginning to dough. Soybeans are blooming but there are reports that in some fields the crop is looking stressed due to water damage from heavy rains in the previous couple weeks."
