Correlations between topography and topsoil chemical properties across different parent materials in evergreen broadleaf forests of Taiwan

Context Topography regulates surface water flow, which in turn alters the horizontal spatial distribution of soil chemical properties. Nevertheless, it remains uncertain whether the influence of topography on soil chemistry is consistent under different parent material conditions. Aims This study aimed to clarify whether (1) soil chemical properties differ and (2) the topographic variables that influence their spatial distribution vary, across the two plots with different parent material conditi
