Conteúdo: | We measured the hydraulic conductivity of a coarse-textured C horizon at 15 sites. The hydraulic conductivity over the soil water potential range of 0 to - 10kPa was measured in situ with the crust test method,and the data were fit to a simple empirical equation. The resulting regression coefficients were found to be significantly correlated at the1% confidence level with the percentage of sand, percentage of silt, bulk density, and porosity of the soil. An equation based only on the sand content of the soil was developed that described 83% of the hydraulic conductivity variation. The equation also successfully described the hydraulic conductivity of a soil with similar physical properties, but was inadequate when applied to a fine-textured soil. The techniqueshows potential  of serving as an easy, reliable, and accurate means for estimating soil hidraulic conductivity.
