This study combines survey information and GIS based optimization model to identify the optimal distribution of broiler litter in crop production. The results obtained provide more plausible transportation routes than the method that does not utilize all these constraints.

Residue management system (RMS) offers increase productivity gain to farmers by increasing the organic matter. Farmers have failed to realize this gain and consequently have not adopted RMS in cotton cultivation. Benefit of adopting RMS system appears sooner than farmers would think.

We used a memory shortening transformation method to forecast the future prices of the seven selected commodities in the Southeast USA. These forecasted prices were used to find the optimal crop selection in a model farm in a representative county of each of the ten states in the Southeast US...

We calculated the profitability of using broiler litter as a source of plant nutrients using the phosphorus consistent litter application rule. The cost saving by using litter is 37% over the use of chemical fertilizer alone to meet the nutrient needs of major crops grown in Alabama. In the...

We calculated the profitability of using broiler litter as a source of plant nutrient using a phosphorus consistent litter application rule. We found that each ton of litter can be transferred cost effectively up to 164 miles from the production facilities. The minimum cost phosphorus consistent...

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...

Numerous studies have addressed the question of the econometric specification of the Environmental Kuznets Curve (EKC). This paper adds preliminary results on nonstationarity and its effect on functional form using a panel data set for the U.S. by state from 1929 to 1994. It is found that...

This study examines if social capital has a role to play in environmental Kuznets curve estimation. It uses information from the World Values Survey to extract the variables representative of the social capital to develop an index using a principal component analysis. Estimation involves the use...

This study utilized a semiparametric panel model to estimate environmental Kuznets curves (EKC) for carbon dioxide (CO2) in 15 Latin American countries, using hitherto unused data on forestry acreage in each country. Results showed an N-shaped curve for the region; however, the shape of the...

This study investigates reasons for adoption of best management practices (BMP), crawfish farmers’ participation in the Environmental Quality Incentives Program (EQIP), and economic impacts of BMP adoption using data from a 2008 survey of crawfish producers. Most-cited reasons for BMP...
