Crop Rotations for Sustainable Intensification
This dissertation investigates how crop rotation design and nitrogen (N) management can contribute to achieving high and stable yields while improving nitrogen use efficiency (NUE) in arable cropping systems. The research is based on a long-term crop rotation experiment conducted at a high-yielding …

Cropping systems under water-limited conditions: effects of rotation and nitrogen management on yield, resource use efficiency, profitability, and soil properties
… such as the Central Great Plains requires cropping systems that balance yield, resource-use efficiency, and economic viability. This thesis integrates results from field studies conducted at different temporal scales, location and under different water-management conditions to evaluate how …

Effect of rotation, organic inputs and tillage on crop performance and soil quality in conventional and low-input rotations in central Iowa
… though the benefits of low external input (LEI) cropping systems to crops and soils are well recognized the specific links between cropping practices and associated soil quality and crop responses are not yet clear. In the Marsden plots in central Iowa, crop yields and input use efficiency have …
