Soils Characteristics in Maize Based Farming System of Western Oromia, Ethiopia

Understanding soil fertility status is a prerequisite to implement appropriate soil management practices for sustainable agricultural production and productivity. In view of this, a study was conducted at Kejo and Ongobo farmers’ fields, located at GobuSeyo District of East Wollega Zone of Oromia region in 2011. To investigate soil characteristics, Soil samples were collected from the profiles of the genetic horizons for the analyzing the selected physicochemical properties. The results of the study revealed that the soils had strong coarse sub angular blocky structure at Ap horizon, whereas to angular blocky structures at the B horizon. The soil textural class of both profiles was clayey with the clay fractions being the highest and increased consistently with depth. The bulk density values ranging from 1.25 g cm-3 at the Ap horizon to 1.40 g cm-3 at the Bt4 horizon. The pH-H2O were strongly acidic ranging from 5.27 at the Ap horizon to 5.83 at Bt2 horizon. The soil organic matter (SOM) contents of the soils ranging from 0.62% at the Bt2 horizon to 3.78% at the surface horizon, whereas total N ranging from 0.03 to 0.19%, available P from 0.62 to 4.0 mg kg-1 and CEC from 11.84 to 22.47 cmolckg-1 soil.Available Fe ranging from 7.24 to 33.68 mg kg-1, Mn from 2.37 to 83.91 mg kg-1, Zn from 0.013 to 0.314 mg kg-1 and Cu from 0.16 to 2.32 mg kg-1 in the soil and showed decreasing trend with profile depth. The result of the study showed that the soils of the study sites had poor chemical fertility and integrated soil fertility management practices can improve the current situation.
