Needed rainfall has helped with crop growth across Iowa.
Landus Cooperative Field Agronomist Zach Minnihan says not only has rainfall positively impacted crops, so have the cooler temperatures.
“You can definitely see the corn and soybeans really starting to close the rows and get some foliage. A corn plant can put on a leaf every three days, roughly when it’s maxed out on its growing degree days. It doesn’t take very long to get that corn up, and out, and to tassel, at the reproductive stage.”
Minnihan points out some of the drought-related stress on crops has subsided compared to how it was a few weeks ago.
“Your 1-4 o’clock in the afternoon, it almost looks like a pineapple plant, I think, we’re not going to see for a little while, just being in the 80s and having some healthier corn with this rainfall. But again, if we get back into a July stretch or an August stretch with this stuff, it doesn’t take very long to get back into kind of a critical stage or not ideal growing conditions in our state.”
According to the most recent crop progress and conditions report from the Iowa Department of Agriculture and Land Stewardship, last week corn was 60-percent good to excellent condition and soybeans were 58-percent good to excellent.
