Abstract
During a sampling period extending from May 07 through August 13, 1985, plant biomass, soil temperature, soil moisture, and other selected biophysical variables were collected on a weekly basis at 12 sample sites distributed along a 200 km east-west trending transect in west-central Oklahoma. Correlation coefficients showed temporal and spatial relationships between dry mean biomass and the relative location of sample sites along the transect, Universal Transverse Mercator coordinate location of each sample site, sample site elevation, and sample week (-0.43, +0.43, -0.54, and +0.42, respectively). A multiple regression analysis showed that 84.5 percent of the variation in plant biomass could be explained by a combination of collected biophysical variables: soil texture, week of data collection, location of the sample site, soil moisture, soil temperature, heat units, and potential evapotranspi ration.
