Dr. Laura Lindsey, Extension Soybean and Small Grains Specialist at The Ohio State University, shared insights from her agronomic research on soybean cyst nematode (SCN), biological seed treatments, harvest timing, and crop management decisions. Her work focuses on helping growers improve soybean productivity and manage production risks.
One of Lindsey's early research projects examined the prevalence of Soybean Cyst Nematode (SCN) across Ohio. A statewide survey of 299 soil samples found that 60% to 80% of sampled fields contained SCN, despite many growers believing their fields were free of the pest.
Lindsey also participated in the Science for Success initiative, a multi-state effort evaluating biological seed treatments. The research found that yield responses from biological products were often inconsistent, highlighting the challenges of maintaining effective microorganisms under field conditions.
Weather-related harvest challenges were another important area of study. Research conducted during the 2024 and 2025 growing seasons showed that delayed harvests can result in substantial yield losses, particularly when crops experience extreme weather conditions.
In western Ohio, severe drought in 2024 was followed by heavy rainfall and humidity associated with Hurricane Helene. These conditions contributed to pod shattering, seed damage, and crop losses in soybean fields.
Lindsey also emphasized concerns about late-season seed quality. Warm and wet conditions during seed fill can increase the risk of fungal infections and diseases such as purple seed stain, making timely harvest an important management practice.
A major focus of her current research is the Battle for the Belt project, which examines whether corn or soybeans should be planted first when spring fieldwork opportunities are limited. The study compares crop performance across five planting dates ranging from late March through the third week of June.
Research trials are being conducted at three Ohio locations over multiple growing seasons. Results have highlighted important differences in how corn and soybeans respond to the same environmental conditions, providing valuable guidance for planting decisions.
Lindsey will present additional findings from the project at the Minnesota Crop Pest Management (CPM) Short Course on December 9, 2026, in Minneapolis. The event will offer farmers and agronomists the latest research-based insights on crop production and management strategies.
