The experiment investigated how selected physical soii properties were affected by tram pling on compacted livestock trails. Two adjacent sites with similar ecological conditions were choosen as the study area. The control site consisted of an ungrazed exclosure. The other site was a heaviiy grazed range site with compacted trails. The range site has been grazed heaviiy by sheep and water buffalo, while the exdosure has been protected from grazing for decades. The experiment used a completely randomized design with three replications for each treatm ent. Data were analyzed using analyses of variance. Soii core samples were collected from 36 soii profiles at the 0-10 cm depth in each treatm ent site. The soii sampies were examined for soii texture, percentages of fine (<2 mm) and coarse (between 2-5 mm, and >5 mm) soii fractions, percentage of root mass, dispersion ratio, particle density, bulk density, total porosity, saturated hydraulic conductivity, saturation capacity, moisture equivalent, pH, electrical conductivity, and organic m atter. Additionally, soii compaction was determined using a pocket penetrometer at the soii surface of each soii profile hefore the collection of samples. Heavy tram pling reduced saturation capacity, saturated hydraulic conductivity, moisture content at the field capacity, and porosity but increased soii bulk density and com paction on the trails.
