Sammanfattning
This study tests relationships between, on the one hand, field-saturated infiltration rate into the uppermost sloping soil layer (K-fsi) and field-saturated hydraulic conductivity in soil horizons (K-fsh) and, on the other hand, in situ determined macropore sizes in soil profile descriptions. It was carried out at six locations along a transect on a slope with loamy soils. The macropores were classified into representative size indices based on pore diameters (P-td) and pore areas (P-ta). A strong relationship was found between K-fsi and P-ta, and between K-fsh and P-td. The approach is promising and the methodology could be further developed with the aim of generalizing the functional relationships, so that K-fs can be estimated in areas where soil survey databases contain information on pore size abundance but lack K-fs values
