This dataset contains the raw experimental data underlying the manuscript

"Effect of biochar and basanite on maize yield, fertilizer efficiency and phosphorus sorption in a tropical Oxisol"

by Meyer zu Drewer, Roobroeck, Maritim, Lotz, Kammann, Hartmann, Broszat, Schmidt, and Hagemann.

The data were collected during a three-season maize field trial on an Oxisol in Siaya, western Kenya (2023–2025), and during a complementary six-week in-vitro phosphorus sorption batch experiment.
