The Roles of Labor and Profitability in Choosing a Grazing Strategy for Beef Production in the U.S. Gulf Coast Region

Comparisons are made concerning labor required and profitability associated with continuous grazing at three stocking rates and rotational grazing at a high stocking rate in the U.S. Gulf Coast region. A unique data set was collected using a time and motion study method to determine labor requirements. Profits are lowest for low stocking rate– continuous grazing and high stocking rate–rotational grazing. Total labor and labor in three specific categories are greater on per acre and/or per cow bases with rotational-grazing than with continuous-grazing strategies. These results help to explain relatively low adoption rates of rotational grazing in the region.labor requirements, rotational grazing, stocking rate, time and motion study, Agribusiness, Food Consumption/Nutrition/Food Safety, Industrial Organization, Labor and Human Capital, Livestock Production/Industries, Q12, Q24,

The Economics of Rotational Grazing in the Gulf Coast Region: Costs, Returns, and Labor Considerations, Phase II

Profitability and labor associated with rotational grazing at three stocking rates and continuous grazing at a medium stocking rate are compared. On a per-acre basis, profits are lowest for low stocking rate rotational grazing. Labor is greatest on both per-acre and per-cow bases with high stocking rate rotational grazing.Time and Motion Study, Conservation, Louisiana, Cow-Calf, Farm Management, Production Economics, Q16,

Measuring Eastern Redcedar (Juniperus virginiana L.) Mass With the Use of Satellite Imagery

Eastern redcedar (Juniperus virginiana L.) is an aggressively spreading native species in Oklahoma grasslands. It decreases rangeland forage production, and has been implicated in reducing stream flow and groundwater recharge. Industrial-scale plans to use redcedar as a biofuel source are being considered. Optimal placement of redcedar-based industries requires determination of redcedar availability. Such large-area inventories of redcedar mass can be practically addressed via aircraft or satellite remote sensing. Therefore, we conducted a study in central and western Oklahoma to develop and test a remote-sensing-based allometric equation relating redcedar canopy area to aboveground dry mass (AGM). We used automated methods to measure tree canopy area from georectified, pan-sharpened, multispectral QuickBird images having a spatial resolution of 0.45 m2 per pixel ground sample area. We also measured the canopy area and fresh and dry mass of these trees with the use of destructive sampling techniques. Regression analysis showed that satellite-derived measurements of canopy coverage explained about 85% of field-measured redcedar dry AGM in the study plots. The resulting allometric equation was applied to an independent data set, yielding dry AGM of 38.2 metric tons ha-1, which was well within the field-measured range of 36-43 metric tons ha-1. The allometric equation was then applied to Natural Resources Conservation Service measurements of redcedar canopy coverage for 17 counties in Oklahoma, to determine that the area of interest contains a median value of about 11.5 million metric tons of redcedar AGM. These results indicate that 0.45-m2 spatial resolution multispectral imagery can be a useful tool for rapid and reliable measurement of redcedar dry AGM.The Rangeland Ecology & Management archives are made available by the Society for Range Management and the University of Arizona Libraries.
