Iron & Clay Cowpea and Cover Crop Inoculation

In the hot and humid subtropics of the Texas Rio Grande Valley, Iron and Clay Cowpea (Vigna unguiculata) can be used to cover the soil during the spring, summer, and fall. Cowpeas fix nitrogen, provide habitat for beneficial insects, reduce wind and water erosion, and more. In this video, Colin Mitchell and Lindsey Richards from the Subtropical Soil Health Initiative discuss the benefits of Iron and Clay Cowpea and lay out the process for inoculating legume cover crops and checking to see if they are creating active nodules–putting nitrogen into soils that will be bioavailable for the next cash crop.
