Book Description
Global crop production must substantially increase to meet the needs of a rapidly growing population. This is constrained by the availability of nutrients, water, and land. There is also an urgent need to reduce the negative environmental impacts of crop production. Collectively, these issues represent one of the greatest challenges of the twenty-first century. Sustainable cropping systems based on ecological principles are the core of integrated approaches to solve this critical challenge. This special issue provides an international basis for revealing the underlying mechanisms of sustainable cropping systems to drive agronomic innovations. It includes review and original research articles that report novel scientific findings on improvement in cropping systems related to crop yields and their resistance to biotic and abiotic stressors, resource use efficiency, environmental impact, sustainability, and ecosystem services.

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.
