This study was entitled with: The impacts of traditional stone lines /kabi-lines /and soil management practices of agronomic erosion controls on soil textures, soil bulk density and soil moisture content at Ifabas / Jarra /Community Watershed West Harareghe Zone Oromia National Regional State Ethiopia. This study had been carried out to observer soil texture using field testing methods and to examined soil moisture contents and soil bulk density under treated and none treated farmlands in relation to soil management practices of agronomic erosion controls. This study was intentionally, used complete random block design (CRBD) which was preferred to observe the variations between dependent and independent variables. The total soil samples was 54 composite soil samples which were collected from three blocks or sub-watershed of Ifabas community watershed to test soil texture using forefinger and thumb rule and mortar and pestle or Ferro and 2lt highland crushed method of field testing. The total of 54 soil samples were collected without made composite soil samples to determine soil bulk density and soil moisture content. Moreover, the soil samples of the total 18 composite soil samples were collected to test soil texture by used local un-graduated cylinder and 30cm rural ratio method. Soil samples were replicated three times to approach accuracy and reduce biasness. The soil data were subjected to EXCEL and multiple-way of Analysis of Variance (multiple-ANOVA) following the General Linear Model (GLM) of Multivariate multiple procedures of SPSS window version 23 computer based software to observe the variations exited between dependent and independent variables. The analysis was carried out for soil texture, soil BD and soil MC The results of the study were observed the variations at significant level of P≤0.05. The results of un-graduated cylinder and 30 cm ruler ratio reading method had showed that insignificant variations between blocks (BS) and blocks with treatments (BS*TRS) interaction effects of sand, silt and clay soil textural fractions at(P=0.703, P=0.175, P=0.388, P=0.267, P=0.811 and P=0.199), respectively whereas between treatments interaction effects of sand and clay soil textural fractions had showed that, the significant variations at (P=0.002 and P= 0.023) but silt soil textural fraction had showed that, the insignificant variations at (P=0.091). It needs ties at intervals, maintenance and burying of the larger stones under the soil surface.
