Cooler weather in late July was a welcome relief from the heat and humidity which seemed to dominate June and early to mid-July. With less rainfall in the past two weeks, the lower temps are a good combination to finish out corn pollination and begin the grain fill period. Most ears show excellent potential. The main risk for the grain fill period is excessive heat, including night-time heat, and of course, rainfall. Wind and hail are always a threat, but the area got past the critical period for greensnap in good shape.

Corn and bean prices bottomed on Friday the 13th. Corn dropped to $2.98 per bushel (local cash bid) while beans hit a 10-year low at $7.49. That price was more than three standard deviations below the average for the year, which has less than 1% chance of occurring. Both prices have recovered about 30% of the price loss from May 25th to July 13th. Traders look at 38% and 50% retracements as important market signals, which could point to a little more price improvement just based on chart signals. A big announcement on settling trade issues could move beans substantially higher.
