Resumo(s)
Soil texture influences significantly soil hydraulic properties, which due to soil he-terogeneity normally present large spatial variability. The variability of soil reten-tion θ(h), and hydraulic conductivity K(h) curves, in 11 of the 12 texture classes of the diagram of Gomes e Silva (1962) was studied. For each textural class, average, maximum, minimum, and the standard deviation values for the Mualem van Ge-nuchten parameters are presented based on 558 θ(h) and 245 K(h) curves deter-mined in undisturbed soil samples which are included in the PROPSOLO database of Estação Agronómica Nacional. An av-erage function describing θ(h) and K(h) in each textural class is also presented
