We’ve made it to July. Looking across the state, I see tall stands of corn, and sometimes I wonder if the saying “knee high by the Fourth of July” will change to reflect the faster maturation. I mean, it’s even hard to justify for a guy like Anthony Davis. Anyway, I do hope everyone had a safe, enjoyable, and restful Fourth, and that your crops are progressing favorably.
Timely rainfall during the growing season is critical to the success of any farming operations. Corn, a perfect example, is starting to move into pollination, when the plant has high water demands. According to the latest Kentucky Crop Progress and Condition Report on July 6, 31% of Kentucky corn is now in the silking stage. Dr. Chad Lee's guide, Corn Irrigation, lists the average daily water needs of corn through each respective growth stage. These numbers peak during early tassel, silking, and blister kernel at just over three-tenths of an inch per day.
We need a lot of rainfall at this time of year and, luckily, we did see some significant accumulations last week, most of which fell on Thursday with the passage of a cold front. Overall, the state averaged 1.73 inches for the week, marking the highest weekly average since early May. Some folks saw much more than others. As you look at the map below, portions of the Southern Bluegrass, including Fayette and Clark Counties, saw 4-6+ inches, which resulted in flash flooding across the area. While higher totals were fairly uniform across the state, there were also some small areas across Central Kentucky that recorded less than a half inch.
