Released September 24, 2013 by The Climate Corporation, this week’s report contains the following details:
- Corn Crop Progress maps for whole Corn Belt and individual Corn Belt states
- Comparison of corn crop progress: September 13, 2012 vs. September 13, 2013
Corn Belt field-level estimated Corn Crop Progress:
March 20, 2013 to September 13, 2013
Individual state field-level estimated corn crop progress maps can be seen at the links below:
Today's map shows a dramatic progression into dent (pink) and black layer (purple) growth stages compared to the August 25th analysis. It shows that corn has or is quickly approaching maturity in almost all areas of the corn belt. Our crop progress model shows that a few very late maturing spots do still remain, mostly in Iowa, Minnesota and Wisconsin, where the corn crop is still estimated to be in either the milk or dough stage. These are the areas that we are watching most closely as having the possibility for experiencing yield-limiting freeze damage this fall (see our freeze risk analysis in last week’s blog post here)

While showing local variation, the year-over-year comparisons of 2013 versus 2012 corn crop progress are now starting converge as we approach the end of the growing season. Our analysis shows that virtually all of the US corn crop was at black layer as of September 13, 2012, and while this year’s crop is certainly behind normal, it is quickly approaching maturity as well.
