Gallatin County farmer Matt Raben puts his corn and soybean harvest at roughly half complete, with fieldwork underway about a week ahead of his normal schedule after starting roughly four weeks ago.

Raben, who grows corn and soybeans in southeastern Illinois, describes the harvest as smooth so far. "We started probably 4 weeks ago, which is a little above our average, so moving along okay," he says.

The pace matters for the region's basis picture. An early start on harvest in southeastern Illinois typically means faster-than-usual grain movement to elevators and processors along the Wabash and Ohio river corridors, though Raben's report is a condition observation from the field, not a weighed, delivered result.

Yields, he says, have been good — an early read that growers across the region will check against combine yield monitors and scale tickets as more acres come off. Reports like Raben's sit ahead of USDA's survey-based measurements, which aggregate county and district yields after harvest data are collected and reported in later crop production releases.

For growers, harvest timing ties directly to margin questions. An above-average start compresses the window for deciding whether to store grain and wait on carry or sell into harvest-time basis levels, and it affects drying costs — an early, dry fall can trim the propane and natural gas bills that erode corn margins in wetter years.

Raben's roughly 50% completion figure offers one data point for southeastern Illinois as the state's corn and soybean harvest progresses. Brownfield's network of grower reports will continue to track pace and yield observations as combines move across the region in the weeks ahead.
