Our weather continues to be mild but mostly dry during the past two weeks. The southwest parts of this region had more rain, but our entire area would benefit from a good rain soon. Temps haven’t been overly warm, so we are not seeing moisture stress yet except for in very light soils. The next two week weather outlook calls for above average temps and normal chances of rainfall. Timely rainfall will become more important as the temps increase.

Most corn looks good in this area and is on schedule to mature on time. The April or May planted corn is starting the milk stage when kernels are yellow on the outside and milky white on the inside. The number of kernels are set but not size or weight. Favorable weather through the end of August will increase yield this fall. Corn planted in June is progressing but remains behind schedule. Yields will be more variable on the late planted corn and farms that have poor drainage.

Soybeans are in their most critical stage over the next two weeks. They are making pods and adding top growth at the same time. Most of the beans in this area look healthy, but are somewhat smaller than normal. Plenty of rainfall and normal temps during this stage will add significant yield, but the beans that are very small now have limited potential. Many farms are getting sprayed for aphids and fungal diseases this week.

The corn market crashed after Monday’s USDA report which estimated U.S. corn planted acres at 90.0 million acres up 2.0 million compared to most estimates. Corn yield were set at 169.5 bushels per acre nationally up 4.6 bushels per acre from the average yield estimate. This report was a big surprise considering the huge amount of unplanted acres in late June across the Corn Belt. It seems very likely that both the acres and yields will end up less than USDA’s current projection, but we probably won’t find out until after harvest.
