SYNOPSIS

The earlier heat and lack of rain over the last 4 to 5 weeks brought an earlier senescence for both corn and soybeans. Some areas received a few tenths with the last storm that came through with the cold front, but it was too little, too late. Corn is just about at black layer, with some testing at 19.5 to 24% moisture. Many in the surrounding counties are getting ready to start harvest. The 3.5 maturity soybeans are just starting to turn R7, but the 4.0s are mostly green or at R6.
