Characterization and Classification of Agricultural Soils of Segen Zuria District, Konso Zone, Southern Ethiopia

Characterization and classification of soils reveal the soils’ potential and limitations for utilization. To describe and classify soils of the study site, a research was carried out in the Segen Zuria District in Southern Ethiopia. Laboratory analysis, field survey, and description of soil morphology are part of the study. Four representative soil pedons were opened and described in the field. From the designated horizons, soil samples were collected, and laboratory analysis was performed. The identified genetic, physical, and chemical characteristics of the soils varied. The soils in the surface horizons of the pedons, except that of Pedon 1, were clay‐textured and ranged in depth from 110 to 200 cm. The bulk densities of the soils ranged from 1.18 to 1.51 g cm −3 . The pH values ranged from 5.9 to 6.9. Available phosphorus levels ranged from 0.96 to 9.89 ppm, while their organic matter contents ranged from 0.14 to 3.69 percent. Ca dominated the exchangeable bases of the soils, followed by Mg, K, and Na. Using the World Reference Base classification system, the soils were categorized into three types: humic Pellic Vertisols; aric, cutanic, and endoeutric Haplic Luvisols; and hyperdystric Haplic Umbrisols. The differences in soil types and characteristics offer information for creating appropriate soil management plans. As a result, it is essential to use certain soil management techniques according to the needs of each type of soil that has been determined.
