Crop planting in Wisconsin presents a mixed picture as of early May. While corn planting remains behind the five-year average due to weather conditions and regional disparities, soybean planting has shown remarkable progress, surpassing expectations. An agronomist's insights provide a boots-on-the-ground perspective on planting challenges, emergence trends, and grower concerns.

Corn Planting Progress and Challenges

Despite recent favorable weather in parts of the state, corn planting in Wisconsin is lagging behind historical averages. As of early May, only 16% of the crop was planted, which is slightly below the five-year average. However, the situation varies significantly across regions, with southern growers benefiting from dry conditions while northern areas faced substantial rainfall and cooler temperatures.

The disparity in planting progress stems from differing weather patterns. In the south, warm and sunny forecasts are expected to accelerate corn emergence, with some fields already showing signs of growth. Meanwhile, northern Wisconsin experienced heavy rains and cool spells, limiting field activity. Agronomist Nick Groth anticipates a surge in statewide fieldwork as drier conditions extend into the north. He highlights the importance of timely planting for optimal yield potential and emphasizes that upcoming weather forecasts remain optimistic.

Soybean Success and Emerging Concerns

In contrast to corn, soybean planting in Wisconsin is ahead of schedule, with 17% of the crop already in the ground. This exceeds the five-year average by three percentage points, reflecting early efforts by growers in certain regions. Despite regional variations, soybean emergence has begun, albeit at a modest pace, with some fields showing signs of life in the south.

Groth notes that while planting progress is satisfactory overall, weed control poses an emerging challenge. Persistent winds have hindered herbicide applications, leading to unexpected waterhemp emergence in southern Wisconsin. To address this issue, growers are considering alternative strategies, including switching to more flexible residual herbicides. These adjustments aim to mitigate the impact of delayed pre-emergence treatments and ensure effective weed management. Groth remains optimistic about the outlook for both crops, underscoring the resilience of Wisconsin's agricultural community despite current obstacles.
