Evaluating SPUR model for predicting animal gains and biomass on eastern hill land pastures


, : Evaluating SPUR model for predicting animal gains and biomass on eastern hill land pastures. Agricultural Systems 34(2): 169-178

The SPUR (simulation of production and utilization of rangelands) model was evaluated for use on eastern hill land pastures. The model was calibrated using the first year of soil fertility, weather and animal data collected from a 4-year study involving crossbred beef cattle grazing Festuca arundinacea pastures in West Virginia, USA in 1981-84. Calibration involved adjusting of plant inputs for max. photosynthetic rate, LAI, root:shoot ratio and the effect of trampling on biomass.
