Book Description
Kura clover has potential as a living mulch for corn production, however understanding the below ground completion is critical for developing best management practices. The first study's objective was to determine kura clover living mulch management effects on root growth. Two kura clover management treatments were compared. In the first a 25-cm band centered on the corn row was suppressed with herbicides. In the second a broadcast herbicide application suppressed all of the kura clover stand. Soil cores containing both corn and kura clover roots were obtained at three distances from the row and at two depths. Root discrimination from these cores was based on 13C ratio analysis. This relationship between 13C and percentage corn roots in calibration samples was linear, and was used to determine corn root percentages within each field core. There were significant corn and kura clover root density depth effects. Corn root density differences were significant between positions, however, significant root growth pattern differences were not observed between treatments. Kura clover management in this study did not affect corn root growth. 13C isotope analysis was a suitable method to discriminate corn and kura clover root materials. As a living mulch, kura clover may also reduce soil erosion, however data are missing. The second study's objective was to determine kura clover cover crop effects on sediment loss, water runoff, and phosphorus losses. Two treatments were compared: a conventionally tilled corn vs. a no-till corn-kura clover living mulch system. Passive infield sediment and runoff collectors were placed in the plots to obtain runoff and sediment from natural rainfall events. The kura clover living mulch treatment significantly reduced the quantity of sediment collected. Runoff was not significantly affected by treatment, but was by date. Runoff patterns were similar for both treatments and total sediment losses remained less than 1 Mg ha−1 for both treatments. When data were segregated as summer and winter events, treatments significantly affected total phosphorus losses in the winter months. The net effect of the kura clover living mulch was to reduce phosphorus loss compared with the tilled surface during the late winter months.

Book Description
Corn comprises 95% of the feed grain production in the United States. Between 2006 and 2016, the area dedicated to corn production in the Southeastern US has increased by 50%. Environmental concerns about increased corn production will require producers to adopt more sustainable practices. The first goal of this research was to identify the best agronomic practices for persistence of white clover in a white clover-corn living mulch system. We found that wide corn rows with narrow herbicide bands was the best combination when corn yield and clover re-establishment were considered. The second goal was to measure the water use efficiency of corn and the soil moisture patterns in a white clover-corn living mulch compared to cereal rye and crimson clover cover crops. The living mulch resulted in reduced water use efficiency compared to the other treatments, and reduced soil volumetric water content in both years.

Book Description
Forages, Volume I, Seventh Edition is the most comprehensive text available for teachers of undergraduate Forages courses. This edition will provide students with a good balance of scientific principles, to aid in integrating the concepts they learn, and practical information on forage identification, plant characteristics, management, and utilization that can be used by forage management practitioners. Grassland ecosystems are extremely complex, including the plant/animal interface as well as the soil/climate/forage interface and the text must support understanding and integration of all of these considerations. The coverage of the science behind the plant characteristics and responses make the book applicable in many parts of the world, while other region-specific management information relates mainly to North America. This edition has been updated to address emerging areas of study, including the use of forage plants as bioenergy crops. The editors also address the renewed national interest in environmental issues such as water quality, global climate change and eutrophication in the Gulf. This edition also addresses the role of forages for wildlife habitat and food sources, another area of increased interest in recent years. These revisions respond to the generational change taking place among forage scientists and teachers in recent years.
