Short summary
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.

Short summary
Studies on soil organic carbon stock (SOCS) in the Sudano-Sahelian part of Cameroon are very rare. Organic C storage decreases with increasing latitude and more than 60 % of the SOCS is stored below the first 25 cm depth. In addition, a good correlation is noted between precipitation which decreases with increasing latitude and the total SOCS, indicating the importance of climate in the distribution of the total SOCS in the study area, which directly influence the productivity of the vegetation.
