The U.S. Geological Survey has determined that irrigation in Arkansas’ Delta is unsustainable. This study examines how irrigation restrictions would affect county net returns to cropproduction. It also considers the effect of planting less water-intensive bioenergycrops—switchgrass and...

Results from a three-year study at University of Arkansas’ Southeast Research and Extension Center in Monticello, Arkansas were used to examine partial returns (PR) from stocker cattle grazing bermudagrass pastures overseeded with ryegrass and crimson clover, white clover, or crimson and...

Using life cycle assessment methodology, this analysis evaluates how two carbon reduction strategies affect cotton plantings regionally and methods used to produce cotton. Because cotton production emits large amounts of carbon, the design of a reduction policy as either excluding soil...

This study estimates the impact of carbon offset payments on land use choices, net producer returns, and carbon sequestration. Loblolly pine is added to traditional cropping choices as a designated carbon-sequestering crop. With a carbon offset price of $15 per ton, pine enters land use on 10...

This study estimates how potential carbon policies targeted at reduction of greenhouse gas (GHG) emissions could affect selection of rice cultivars by conducting a life cycle assessment of GHG emissions and estimating the carbon sequestered for fourteen commonly sown rice cultivars across...

Switchgrass (panicum virgatum L.), a viable option for second-generation renewable fuels, has an extended harvest window with optimal harvest affected by yield, storage losses and nutrient uptake. This research shows that optimal harvest occurs later than maximum yield for Haskell, OK and...

A spreadsheet-based tool that tracks cow-calf producer net returns (NR) and greenhouse gas (GHG) emissions was used to determine the impact of calving season for three typical farm sizes and four fertilization strategies in Arkansas. Economic and environmental changes were examined for spring,...

Concern over GHG emissions has producers analyzing cattle production alternatives. One way producers can modify emissions is by changing herd sire genetics. The ‘Bull Estimator’, part of a recently developed cow-calf profitability and GHG spreadsheet tool, shows that genetic change can...
