Tech man - 6/17/2016 09:39 Noticed the same thing on mine yesterday while spreading urea and AMS. Hopefully that straightens it out. It was sprayed with Halex and ATZ 2 weeks ago. PH should be good because it was had lime applied last fall. Don't see it everywhere but most of our corn on corn looks like this. Corn on beans don't see it at all. Yours looks like Mn def, or possibly Zn. Not S def. | 
What deficiency is this?
