This research presents a competitive dynamic model to evaluate the economic and groundwater quality benefits resulting from the adoption of soil/water nitrogen testing. The model is applied to an irrigated corn production county in the Nebraska Mid-State area where the groundwater contamination...

The Arkansas River in Colorado is confronted with a salinity issue; the majority of this salinity problem is due to agricultural runoff caused by irrigation. Reducing applications of irrigation water through adoption of more technically efficient irrigation systems is one means of improving water...

The uncertainty weather condition could pose some challenge in achieving environmental target. In this study, we use a bioeconomic model to calculate the impacts of alternative management systems. Under different safety-first constraints on the levels of environmental runoff, obtaining from...

GSD is used to determine the risk efficiency of nine different technologies of land application. The analysis shows that organic applications for crop phosphorus needs are the most environmentally efficient. Under producer risk aversion, inorganic fertilizer application is the most economically...

Meta-analyses of past research outcomes are becoming more popular, however, the issue of the panel nature of data has not been empirically investigated. We test various forms of data stratifications into panels for outdoor recreation economic studies but do not find any significant effects,...

Rural counties along the Arkansas River of Colorado are being negatively affected as a result of irrigation induced waterlogging and soil salinization. Mathematical programming is first used to estimate the direct costs of these effects on agricultural production, then input-output analysis is...
