Mapping the Extent of Organic Matter Content, Soil Permeability Rate, Soil Structure and Textural Classes of Kersa Woreda, Jimma Zone, South Western Ethiopia

Abstract

Compatible soil databases are essential for establishing the current status of the earth's components and processes, and for monitoring rates of change in the status of these resources. This study was conducted with the objective of mapping and evaluation of the temporal and spatial distribution of soil organic matter content, structure, permeability and textural classes of kersa woreda. The spatial interpolation model showed that a good performance distribution of soil textural class, structure, permeability and organic matter content. The most dominant soil textural class of the study woreda is sandy loam. The permeability rate of study area is dominated by slow to moderate permeability rate. The maximum soil organic matter distribution of kersa woreda range from 3.94-4.26 percent and the minimum soil organic matter distribution ranges from 2.98-3.316 percent. The major soil structural distribution of the study woreda is medium or coarse granular that cover all parts of the woreda except small area of the woreda.
