Comparison of temporal differences in models of soil moisture and plant biomass variability on the southern Great Plains of the United States

Abstract:

Multiple regression models of soil moisture at 15, 61 and 91 cm depths, and for above-ground plant biomass explained 92, 90, 92 and 88 percent of the variability, respectively, through field data collected in 1986. Multiple regression models developed for soil moisture and plant biomass, through data collected in 1985, answered 83, 91, and 82 percent, and 85 percent of the variability, respectively. Air temperature, precipitation levels, soil moisture and plant biomass for 1985 and 1986 were compared through calculation of means and standard deviations for each field site and for each principal variable throughout the sample period. -from Author
