WebVolcanic soils often have a high aluminum content (Young, 1988) which restricts plant growth in acidic soils (Watanabe and Osaki, 2002). Due to the impermeable nature of the bedrock substrate under the soils, rainwater washes down the slopes and forms streams in river valleys, sometimes causing severe erosion and forming “badlands” ( Young, 1988 ). WebAcid soil, particularly in the subsurface, will also restrict root access to water and nutrients. Aluminium toxicity. When soil pH drops, aluminium becomes soluble. A small drop in pH can result in a large increase in soluble aluminium (figure 1). In this form, aluminium retards root growth, restricting access to water and nutrients (figure 2).
