PMN Offers Two New Soybean Webcasts

Impacts of Subsurface Drainage in Corn-Soybean Rotations

This presentation by Matt Helmers, Iowa State University, will help consultants, growers, and other practitioners in the Midwest region increase their understanding of subsurface drainage and factors to consider when planning or evaluating the need for a subsurface drainage system. Specifically, the impacts of drainage on water movement, crop production, and nitrate-nitrogen loss will be described.

Benefits and Utility of Bedding Systems for Improved Productivity and Profitability of Soybean Production in the Mid-South U.S.

Trey Koger, Mississippi State University, shows how soybean productivity and profitability may be improved through the use of bedding systems in soybean production. The use of raised bedding systems helps to increase and improve the consistency of soybean yields, especially in wet years. Because the topography of the Delta region is predominately flat, drainage is critical.


Both presentations are part of PMN’s Focus on Soybean resource.
