Combines rolling across South Dakota, Iowa and Missouri are turning up sprouting corn and soybeans in unusual colors — green, purple, nearly black, yellow and dark gold to brown — according to grower reports from the region.

Jeff Kloucek, a crop consultant and farmer in eastern South Dakota, described the variation directly. "There's normal soybeans, green beans, purple beans, some that are almost black, yellow or a dark gold to brown," he says.

What are growers seeing in the field?

The reports cluster around two distinct symptoms. Corn is sprouting in the ear in some fields, a condition that typically signals prolonged moisture exposure ahead of or during harvest. Soybeans, meanwhile, are showing up in a spectrum of discoloration rather than the uniform mature gold growers expect at harvest.

Kloucek's account is one of the more detailed field reports so far this season, coming from eastern South Dakota. Brownfield Ag News, which reported the story, indicates similar observations are surfacing in Iowa and Missouri as harvest progresses.

• Sprouting corn reported in fields across the three states
• Soybean discoloration ranging from green and purple to nearly black
• Yellow and dark gold to brown beans also appearing alongside normal crop
• Reports come as combines are actively harvesting

Why does discoloration matter for growers?

Discolored and off-color soybeans are more than a cosmetic issue at the elevator. Grain buyers typically apply discounts or dockage for damaged or discolored beans, and sprouting in corn indicates physiological quality loss that can cut test weight and storability. For farmers already managing tight margins, quality dockages compound the hit from any yield shortfall tied to the same weather conditions that caused the discoloration.

The geographic spread — from eastern South Dakota through Iowa into Missouri — suggests the underlying cause, likely weather-related stress during maturation, affected a broad band of Corn Belt acreage rather than isolated fields.

Condition reports, not harvested results

These are in-field condition observations made during an active harvest, not final quality or yield data. Elevator-level reports on actual dockage rates, statewide yield estimates, and USDA crop progress figures will provide the measurable picture of how widespread the damage is and what it costs growers.

Condition reports like Kloucek's often serve as early warnings. They tell farmers where to prioritize rapid harvest to limit further quality deterioration, and they give buyers and processors an early read on regional supply quality.

As harvest advances across the three states, expect clearer data on how much of the soybean crop carries discoloration discounts and how widely sprouting has cut into corn quality.
