From Pat Supple | Corn Yield Snapshot

Cargill Eddyville travels doing yield checks in the area they purchase grain in August- September.
Maurice Gardner from Cargill and I did checks today .
 
Traveled 150 miles in 5 counties Jasper, Tama, Poweshiek, Iowa & Mahaska for the yield checks.
 
 
 
 
""23 fields" were checked in this area on the tour today.
30 % of fields corn on corn & 70% corn on soybean ground
65%  had been treated with a fungicide.
Multiple nitrogen sources and applications seemed to have greener corn--higher yields checks
No fields had wind-hail damage to the corn crop
Rootworms were a non issue on all fields.
Leaf diseases weren't present or a problem.
The area checked has probably had 1" of rain in the last 20 days.
