Poultry litter can be used as plant nutrients or cattle feed. Both of these alternatives may increase phosphorus concentration in the nearby watershed. Use of phosphorus consistent litter application rule in nutrient management combined with permit system has potential to curtail the over...

We studied transboundary ground water management problems in the presence of hydraulic fracturing (fracking). We found that the presence of risk suggests a need to exercise caution in fracking. We also found that a cooperative outcome implies the decrease in fracking and the increase in steady...

We used poisson and negative binomial models to estimate future demand of recreation trips to a closed site using internet and intercept surveys. Parameter estimates were validated using 1,000 bootstrap replications. Result indicated a significant negative impact of travel time and positive...

One of the challenges in estimating economic impacts of recreational activity and natural resource use is collecting survey data when the underlying population is not perfectly known. We combine bootstrapping techniques with input output analysis to estimate impacts from recreational activity at...

Online surveys have emerged as low-cost data collection approach in empirical researches; however, the validity of data remains questionable. Therefore, we employed a stochastic frontier estimation method to calibrate online recreational expenditure. Study results suggested the presence of...

Poultry litter is a byproduct of poultry production which has potential to cause water quality problem if it is not applied properly on land as a nutrient source. Using survey information available from Louisiana broiler producers, we found that broiler litter is not cost‐effective to...

Market channel alternatives that include garden centers, landscapers, mass merchandisers and re-wholesalers have contributed to the growth of ornamental crops sales in the United States (U. S.). The homogenous subpopulation of the U.S. nursery producer was clustered using mixture of export...
