Saturated hydraulic conductivity (Ks) was estimated as limit condition of infiltration in model sandy substrate. Infiltration was directly measured with a pressurized infiltrometer and Ks was estimated from mathematical analyses based on Philip's equation. The substrate was divided in ten large vessels, nine of them were planted with poplar and one was without vegetation. Our results show differences in Ks estimated for the bare and less rooted vessels in comparison with densely rooted ones. Sandy substrate with high organic matter content shows lower Ks than substrates with low organic matter content.
