#agrisagronomy corn harvest is underway, some of our yield estimates back in August to actual yields today are bit off the mark. Largely due to TKW and kernels/ bus. We used 95k / bus in our estimates, some of those fields are 59K kernels/ bus. Est yield at 198 is now 299.

#agrisagronomy tip kernels are black layered first, shank end will be in a couple of days. Other cobs have pinched shanks that prematurely ended grain fill they are all black layered poor kernel fill you can twist the cob. Tar Spot came in late

#agrisagronomy CHU update May 1st to Sept 11th, approx. 200 behind a year ago. August this year 712 CHU, last year was 744. The deficit really goes all the way back to May, this year 380 CHU last year 564. Cold nights slowed down accumulation.

Still 150 behind max temp in calculation is 30C days over that did not add to CHU
