Abstract

Measured soil characteristics data served as an input to the model to generate the simulated data, subsequently compared and subjected to coefficient of determination (R2) to serve as a goodness-of-fit measurement. The soils textural class varied from Sand, Loamy sand and Sandy loam. There was a good fit between the measured and simulated soil water characteristics for Sandy loam and Sand texture class. For sandy loam soil (R2 = 0.77, Pisture content. A poor fit was observed for loamy sand soil and saturated for hydraulic conductivity for all the textural classes.
