Pedogenesis and root development in a complex geomorphologic setting of the Faroe Islands
Studies of pedogenesis in basaltic soils within the cool, temperate zone were fairly limited. This study looked at pedogenesis and root development in Norðradalur of the Faroe Islands. To a large extent, soil physical and chemical characteristics were determined by sedimentological rather than pedol...
