USDA's most recent progress report shows that 25% of corn is already silking and more will join this week. In light of drought conditions plaguing the majority of the Corn Belt and Mid-South and the heat wave wilting crops in these regions with only limited rain chances ahead, this is especially worrisome. This also increases concerns that all the projected double-crop beans will be planted, let alone turn out well.
Social media has allowed farmers to provide visuals of just how bad (or good) their crops are faring. I once again took advantage of this with my query as to whether your crops were tasseling, and I am ever thankful to those who responded. (Keep 'em coming. Tag me via Twitter (@MeghanPedersen) or shoot me an e-mail.)
Not surprisingly, many of the photos below reflect the toll heat and dryness has had on the crop. But others have fared surprisingly well. This confirms the varied conditions you reported to Chip Flory via his Twitter-based survey regarding crop conditions. He asked you to rate your corn and soybean crops using the following scale: 1=worst-ever yield potential; 5=five-year average; 10=best-ever yield.
The 90 participants who responded for corn averaged a 4.6, while the 81 who responded for soybeans averaged a 5.1. Visit Chip's Twitter page and scroll down to his Tuesday (July 3) morning posts for a state-by-state breakdown.
