13 Jul 2006, 8:33 PM  |  Caring for the Country You can hide this advertisement by registering. present information comparing the fertility of a basalt-derived soil from recent volcanic activity in eastern Australia with a deeply weathered lateritic soil from Western Australia I understand that basalt-derived soil and deeply weathered lateritic soil both differ by their pH, nutrient levels, soil porosity, permeability and soil structure, but can someone be more specific by telling me how they differ. If possible can you please send reference. Cheers. |
