Dry pockets expanding in southwest Iowa

Dryness is a concern for crop farmers in southwest Iowa.

Iowa State University Extension field agronomist Aaron Saeugling says rains have been spotty since early spring.

“You could go as far as a mile or two, sometimes less than that across a section, and there’s a lot of variability in the amount of moisture that we’re getting.”

He tells Brownfield yield potential will suffer if measurable precipitation doesn’t come by the time crops enter reproductive development.

“That’s a key crop physiology development, especially in corn. So that’s going to be something to watch over the 4th of July season, producers (should be) out looking at those fields when they tassel.”

Saeugling says a lot of corn is transitioning to the mid-vegetative stages when drought stress can result in fewer kernel rows.
