Corn Crop Conditions

The latest USDA weekly crop progress report showed corn conditions unchanged from last week with 74% in the good to excellent category.

Using our usual ratings system where the percent of the crop in very poor condition is multiplied by a factor of 2, that in poor shape multiplied by 4, fair by 6, good by 8 and excellent by 10 and summing the results, the crop rating as of September 7 is 774 points.

Since the USDA started keeping records in 1986, this is the fourth highest ranking for this time of year exceeded only in 1986, 1987, and 1992.

Furthermore, as opposed to the usual seasonal pattern of conditions deteriorating as the season goes on, this year ratings have stayed steady and even improved late in the season, a particularly auspicious sign that has only been seen in other years where the U.S. corn yield came in at record levels.

Note that fantastic corn yields are being reported out of the Delta where the harvest has been ongoing for two weeks now.

Talk is that if these types of yields are being seen in the Delta what will they be in the Midwest where growing season weather was uniformly better.

For weeks now we have noted that 2014 is shaping up to be one of these special growing seasons, similar to 1994 and 2004 where final row crop yields were at least 10% above trend with August to final USDA crop reports increasing by 10 bushels per acre (bpa) for corn.

This would project to a corn yield of 176.0-177.4 bpa vs. the last USDA estimate of 167.4 bpa.

We have around 4 billion bushels of corn production; 28% of projected US production, that has not yet dented. These calculations are from the September 7, 2014 crop progress report and the August Wasde. It looks something like 3 billion bushels or 22% of US production has not dented and is in the way of this cold spell. A corn plant that dies prior to dent does not produce usable grain. The text books indicate the corn plant has been known to "shut down" when subjected to prolong periods of cool weather. So even without a frost corn can die without enough heat to keep cells functioning. This appears to be variety specific. The weather forecast, here and many other areas, seems to indicate it will take a week to accumulate the growing degree days that are common, in one day, this time of year. This weather might be a bigger deal than the market believes. Time will tell. Freeport, IL
