Cool weather slows crops
Another cool, wet week has farmers hoping for a change in what has been an uncharacteristic cool and wet crop year so far. Producers continued to struggle with baling hay and draining excess water from feedlots and low-lying cropland.

Although crops are in good condition, many farmers are starting to wonder when the heat units will arrive.
