A Soil Profile Dataset From Central Ethiopia: Morphological, Physical and Chemical Properties, WRB Classification, and Root Count

Abstract

Comprehensive soil profile datasets are essential for understanding and modelling soil and soil processes, yet remain scarce in Sub-Saharan Africa. This is particularly true for full soil profiles combining root observations with soil water retention characteristics. Here, we present a dataset of 50 soil profiles from maize and wheat systems in central Ethiopia, comprising observations and measurements from soil pits described and sampled to depths of down to 2 m. The dataset integrates pedogenic horizons with morphological descriptions, detailed root distribution observations, and analytical data for physical and chemical soil properties obtained from fixed sampling layers. All profiles are classified according to the World Reference Base for Soil Resources. Field photographs are included to document soil morphology and field procedures. The dataset may support improved understanding and modelling of soil processes, soil hydrology, and the relationship between crop roots, soil morphology, and soil properties. It may also support applications in digital soil mapping, and the development of pedotransfer functions. The dataset is publicly accessible in the PANGAEA repository at https://doi.pangaea.de/10.1594/PANGAEA.995660.
