Short summary
The study evaluates the effect of trachyte and basalt powders on soil and maize yield in the Sudano-Sahelian zone of Cameroon. Texture, base saturation, and organic carbon indicate moderate limitations. The climate is favourable for maize cultivation. Rock powder application significantly improves yield, with basalt being more effective than trachyte. The advantage of using rock powders lies in their environmental benefits, long-term effectiveness, and more affordable cost.
