The Uhland type soil core sampling equipment was used to obtain cores 74 mm in diameter and 76 mm high from the surface 0.25 m of an alluvial soil in Louisiana. Samples were taken in pairs; one sample was taken by hammering the cutting head into the soil, and the other sample was taken by pressing the cutting head into the soil using a hydraulic cylinder. Data for 26 pairs of samples showed that the saturated hydraulic conductivity for the hammered samples averaged 2.36 µm/s, and that for the pressed samples averaged 4.28 µm/s. The difference was statistically different at the 99.5% level. Average oven-dry weight of soil in the cores was 6 g greater for the hammered than for the pressed cores.
