N2 - The contribution of individual grain size fractions (2000-500, 500-250, 250-63, 63-2 and < 2 mu m) to bulk soil surface area and reactivity is discussed with reference to mineralogical and oxalate and dithionite extractions data. The 63-2 mu m fraction contributed up to 56% and 67% of bulk soil volume and BET surface area, respectively. Consideration of these observations and the mineralogy of this fraction suggest that the 63-2 mu m fraction may be the most influential for the release of elements via mineral dissolution in the bulk soil.
