As soybean fields across the Corn Belt enter maturity, agronomists emphasize the importance of late-season scouting to determine harvest priorities and minimize potential yield losses. Despite some farmers’ reluctance to check fields once leaves begin turning, experts stress that end-of-season observations can still influence profitability.
Steve Gauck, regional agronomy manager for Beck’s and a farmer himself, notes that late scouting provides critical insight into standability and lodging risks. “One key thing you are looking for is how well a specific field will hold up as they dry down and harvest approaches,” Gauck explains. Fields more prone to lodging or shattering should be harvested first to avoid losses.
Several factors influence standability, including plant genetics, density, stalk diameter, branching, and disease presence. While widespread disease pressure remains limited this season, localized cases of red crown rot and sudden death syndrome have been reported.
Drought stress has also created challenges in certain areas, particularly where rains ended after mid-August. Soybeans in these fields matured unevenly and are more vulnerable to shattering. Some farmers resort to nighttime harvesting with GPS autosteer to take advantage of higher moisture levels, preserving grain weight and reducing shatter losses. Gauck cautions that harvesting too dry not only risks shattering but also reduces bushel weight, cutting into profits.
Early-maturing soybeans are already being harvested in Missouri, with yields surpassing expectations. Many growers report results in the upper 60s to high 70s bushels per acre, far better than anticipated given drought conditions. Early planting and timely pod fill helped these soybeans avoid the worst of late-season dryness.
However, later-maturing soybeans are showing more stress, including aborted pods and reduced seed size. Agronomists expect soil type to play a significant role, with higher water-holding capacity fields performing better than sandy or well-drained soils.
Recent rains are benefiting double-crop soybeans, though most first-crop fields are already in senescence. Despite weather challenges, harvest momentum is building across the Corn Belt, with scouts and farmers alike keeping a close watch on field conditions to optimize yields.
