From the Rows -- Brian Grete -- Final Iowa Results and Thoughts


From the Rows -- Brian Grete -- Final Iowa results and thoughts


After pulling 412 corn samples from the state of Iowa, the average corn yield came in at 180.25 bu. per acre, up 0.8% from year-ago and 10.8% above the three-year Tour average. Compared to year-ago, Iowa crop districts 1, 2, 3, 4 and 5 all came in above year-ago. Crop districts 6, 7, 8 and 9 came in under year-ago. The areas of the state that got plentiful, but not excessive moisture, all had yields that were higher than year-ago. The areas of the state that saw above-normal rainfall this spring and early summer returned lower yields compared to year-ago. Nitrogen deficiency from the excessive rains robbed the crop of yield potential. While Iowa's corn crop is very strong this year -- likely to be record-large in some areas -- crop districts 6, 7, 8 and 9 may put a cap on yield potential.

The 407 soybean samples from Iowa resulted in an average pod count of 1,219.21. That was up 3.9% from year-ago and 15.2% greater than the three-year Tour average. Compared to year-ago, Iowa crop districts 1, 3, 4, 6, 7 and 9 returned soybean pod counts greater than last year's Tour results. Crop districts 2, 5 and 8 -- the three central districts in the state -- had lower-than-year-ago pod counts. While I (we) don't have a solid explanation for why the central three crop districts would have lower pod counts, it could be that the crop in districts 2 (north-central) and 5 (central) Iowa had too little stress. The crop put a lot of energy into building big, bushy beans and wasn't stressed enough to add a lot of pods. The crop in district 8 (south-central Iowa) was impacted by too much water that delayed plantings and/or left the crop sitting in saturated soils.

Chip and I would like to thank all of our hard working crop scouts for four days of dedicated work this week. We've said it thousands of times, but we can't do what we do on Crop Tour without your hard work. We hope to see all of you again in August 2016.
