The dataset comprises 50 soil profiles from maize- and wheat-based farming systems in Central Ethiopia. Soil profile data were collected during field campaigns conducted between 2023 and 2025. Profiles were described in the field to depths of up to 2 m and sampled for laboratory analysis to 150 cm depth. The dataset includes site descriptions, morphological horizon data, laboratory-measured physical and chemical soil properties, soil water retention characteristics, WRB soil classification, and root distribution observations. Field descriptions followed FAO (2006) soil description guidelines, and laboratory analyses were conducted using standard soil analytical methods. WRB soil classification followed the World Reference Base for Soil Resources (IUSS Working Group WRB, 2015), including the assignment of Reference Soil Groups and associated qualifiers. Root counts were conducted in 5 cm depth increments from 0 to 150 cm using a 5 × 5 cm grid, adopting the profile wall method as described by Böhm (1976) and Bublitz et al. (2022). The dataset was specifically collected as validation data for evaluating spatial maps of root-zone plant-available water holding capacity in Central Ethiopia. It may support improved understanding and modelling of soil processes, soil hydrology, and relationships between crop roots, soil morphology, and soil properties. Each data file includes a metadata sheet with variable definitions, units, and structure information to ensure consistent interpretation across dataset components.
