Lot's of yellow corn being observed throughout Iowa early this summer.
Great advice here from Angie!

I am receiving a lot of texted photos & seeing this. This is S deficiency. Much like soil organic N, S must mineralize to be available for plants and when you have dry soils, this process is delayed. Also note, some hybrids will âflashâ symptoms & eventually grow out of it.
