This study was conducted in Arsi Negelle woreda of West Arsi Zone, Oromia regional state. The main objective of the study was to investigate the impacts of soil bund on soil physical and chemical properties in Arsi Negelle woreda. The soil data was collected from sites namely: lowland, midland and highland and from soil bunds aged >4 years, <4 years and control of farmland. Three representative sites were selected purposively for soil sample collection. Stratified random sampling techniques were used for soil samples collection. Fifty-four disturbed and undisturbed soil samples were collected for soil properties analysis from two soil depths (10 and 20 cm). Statistical analysis was done following a completely randomized design (CRD) with factorial experiments and treatments as fixed effect and location of sampling as a random effects. The analysis was carried using R software. Regression analysis was used to relate physical properties of soil with each other. Tukey test was used for comparison of means of treatments when statistical significance is found at P ≤ 0.05. Bulk density (BD) and air-filled porosity (AFP) showed significance difference on treated and non-treated site, respectively. The mean of electric conductivity (EC), total nitrogen (TN), available phosphorous (AP) and organic carbon contents were recorded to be significantly higher (p≤ 0.05) on soil bund ages greater than 4 years (>4years) at both soil sampling depths. Aged soil bunds (treated plots) showed a significant changes on soil physical and chemical properties than control plots. The mean of total nitrogen (TN), available phosphorous (AP) and organic carbon contents were recorded significantly higher (p≤ 0.05) in lowland than highland at both soil sampling depths. In generally, ages of soil bunds and sites had significant effect on many soil physical and chemical properties. The sites and ages interaction had significant effect on bulk density (BD) at both depths at P ≤ 0.05. In conclusion, this study showed that soil bunds had significant effect on many physical and chemical properties of soil in the study area.
