Although this summer has been notably dry and hot, a derecho on July 5 and rainfall for the rest of that week resulted in improvement in the condition of some Iowa corn and soybean crops. The percentage of the corn crop rated good and excellent increased as of July 10 jumped to 81 percent from 77 percent the week before. Soybean crops increased by two percent, improving from 79 percent from 77 percent. 

Justin Glisan, a state climatologist, said the statewide weekly average precipitation was 1.01 inches above normal during the week of July 4, sitting at 2.12 inches.  

The U.S. Department of Agriculture reported Monday that 72 percent of topsoil was rated adequate and three percent sat rated very short. Subsoil moisture condition was rated 66 percent adequate and 22 percent short. 

Although some of Iowa’s crops are in better condition than before the rain, Ohio farmers are still concerned about the impact of the dry period on crops. As of July 10, soil in Ohio sits at 73 percent adequate and just 7 percent of soil contains surplus moisture. 

If droughts continue, crop size and quality can decrease, crop prices can increase, and crop cleaning practices may lessen with a lack of water.
