Measuring the estimation bias of yield response to N using combined on‐farm experiment data
Journal of the Agricultural and Applied Economics Association, EarlyView.Abstract Accurately evaluating yield response to nitrogen is essential for increasing farm profitability. Data often come from randomized experiments, ensuring nitrogen is independent of other factors. However, when data from multiple experiments are combined, as many studies do, correlations between nitrogen and unobserved field heterogeneity can ...

Surface water irrigation reservoirs improve groundwater recovery in a heavily stressed aquifer
Journal of Environmental Quality, EarlyView.Abstract Expansion of irrigated cropland area in eastern Arkansas has led to the formation of regional cones of depression and creation of critical groundwater areas for the Mississippi River Valley alluvial aquifer (MRVA) in Arkansas. In response, use of surface water reservoirs for irrigation in the Grand Prairie critical groundwater area (GPCGA) has

Are historical trends in weather consistent with model predictions in the Central United States?
Journal of Environmental Quality, EarlyView.Abstract Model projections predict increasing temperatures and precipitation change in many locations in the Central United States. To provide perspective on what these trends might bring relative to what has already happened, we compared historical temperature and precipitation change with what models from the Coupled Model Intercomparison Project ...

The Journal of Wildlife Management, EarlyView.We incorporated landscape suitability into a trumpeter swan range expansion model. We estimated a 4.4% (95% CI: 2.0–6.9%) annual range expansion rate from 2023 to 2033, with expansion occurring in the Prairie Pothole Region of the Dakotas and the Boreal Shield and James Bay Lowlands of Canada. Abstract The Interior Population of trumpeter swans (Cygnus
