Senna siamea trees recycle Ca from a Ca-rich subsoil and increase the topsoil pH in agroforestry systems in the West African derived savanna zone por Vanlauwe, Bernard, Aihou, K., Tossah, B.K., Diels, J., Sanginga, Nteranya, Merckx, Roel

“…The functioning of trees as a safety-net for capturing nutrients leached beyond the reach of crop roots was evaluated by investigating changes in exchangeable cations (Ca, Mg, and K) and pH in a wide range of medium to long term alley cropping trials in the derived savanna of West Africa, compared to no-tree control plots. Topsoil Ca content, effective cation exchange capacity, and pH were substantially higher under <em>Senna</em> <em>siamea</em> than under <em>Leucaena leucocephala</em>, <em>Gliricidia sepium</em>, or the no-tree control plots in sites with a Bt horizon rich in exchangeable Ca. …”
