A study was carried out to evaluate the impact of different land use types on particular soil physical and chemical parameters in the Liban Jawi district, West Shewa Zone, Oromia, Ethiopia. Land use changes significantly influence soil quality by altering its physical and chemical properties, and understanding these impacts is essential for sustainable land management; however, in areas like Liban Jawi District, West Shewa Zone, Ethiopia, limited information exists on how different land use types affect soil characteristics. The three land use types: Forest lands (FL), Grazing lands (GL), and Cultivated lands (CL) were represented in the 9 soil samples collected using an auger and bulk density (BD) by core sampler for the analysis of soil properties at a depth of 0-30 cm with three replications. The analysis of soil samples was carried out in the Ambo University Chemistry laboratory. The result of the research showed that the textural classes of GL and CL were loamy sand, whereas, sandy loam in the FL. The BD recorded in the three land use types was statistically insignificant. The highest organic carbon (OC) 7.06%, Available phosphorus (Av.p) 70.7 mg/kg, Total nitrogen (TN) 0.82%, cation exchange capacity (CEC) 49.86 cmol/kg, electrical conductivity (EC) 0.08 ds/m, Calcium (Ca) 13.17 cmol/kg, Magnesium (Mg) 8.47 cmol/kg, and Potassium (K) 2.56 cmol/kg were recorded in FL, followed by GL. The study revealed a significant (P < 0.01) variation among the land use types for pH, OC, TN, Ca and Na. However, land use types did not significantly affect Av. P, CEC, Mg, K, and EC. It is possible to conclude that soil physicochemical properties differed by land use due to the exhaustive exploitation of land resources and improper soil management systems in the area, highlighting the need for better soil management in cultivated and grassland areas. Therefore, there is a need to develop integrated soil management practices that could sustain agricultural productivity and production.
开展了一项研究，以评估埃塞俄比亚奥罗米亚州西谢瓦地区利班贾维区不同土地利用类型对特定土壤理化参数的影响。土地利用变化通过改变土壤的物理和化学性质，对土壤质量产生显著影响，了解这些影响对于可持续土地管理至关重要；然而，在埃塞俄比亚西谢瓦地区利班贾维区这样的地方，关于不同土地利用类型如何影响土壤特性的信息有限。使用螺旋钻采集了9个土壤样本，代表了三种土地利用类型：林地（FL）、放牧地（GL）和耕地（CL），并使用取芯器测量了容重（BD），以分析0至30厘米深度土壤性质，共进行了三次重复。土壤样本分析在安博大学化学实验室进行。研究结果表明，GL和CL的质地类别为壤质砂土，而FL为砂壤土。三种土地利用类型记录的BD在统计学上无显著差异。FL中记录的有机碳（OC）含量最高，为7.06%，有效磷（Av.p）为70.7毫克/千克，总氮（TN）为0.82%，阳离子交换容量（CEC）为49.86厘摩尔/千克，电导率（EC）为0.08 毫西门子/米，钙（Ca）为13.17厘摩尔/千克，镁（Mg）为8.47厘摩尔/千克，钾（K）为2.56厘摩尔/千克，其次是GL。研究表明，土地利用类型在pH值、OC、TN、Ca和Na方面存在显著（P < 0.01）差异。然而，土地利用类型对Av. P、CEC、Mg、K和EC没有显著影响。可以得出结论，由于该地区土地资源的过度开发和不当的土壤管理系统，土壤理化性质因土地利用而异，这突出了在耕地和草原地区进行更好土壤管理的必要性。因此，需要制定能够维持农业生产力和产量的综合土壤管理措施。
