Soil properties predicted from mid-infrared spectral (MIRS) analysis of soil samples collected in 2023 (second year) before and/or after establishing on-farm trials on yield response to lime rates in Ethiopia

<p> Selected soil properties were predicted from 232 topsoil samples subjected to spectral analysis (MIRS). A subset of samples were also subjected to wet chemistry analysis, and results were used to calibrate a machine-learning algorithm developed by the International Centre for Research in Agroforestry (ICRAF) in Kenya. Coordinates were truncated to protect farmer's privacy.</p>
<p> Unless specified, all properties were predicted. This dataset can be linked with yield data (coming soon) and previous soil analysis data (<a href="https://hdl.handle.net/11529/10549136">https://hdl.handle.net/11529/10549136</a>) through the unique farm identifer "fid". </p>
