Abstract:
Research was conducted on reconstructed soil cores compacted at varying levels of water content and static pressure. The pressure levels were chosen in an effort to simulate the static conditions that might occur during field cultivation and forest logging operations. Sorptivity, Sₒ, and void ratio, e, were measured from the soil cores. The statistical analysis showed that both sorptivity and void ratio showed similar responses to different degrees of soil compaction and there was a correlation coefficient of 0.89 between Sₒ and e. The result also showed that sorptivity was more sensitive to the change in soil structure than in soil-water content.
