5. Land Capability Assessment Matrix The Land Capability Assessment Matrix has been developed for that section of the proposed allotments relevant to the investigation. It specifically relates to the proposed or likely Land Application Areas. The General Characteristics Ratings are determined by direct measurement on site, provided data or inferred from site/soil conditions present or historical investigation undertaken by Provincial Geotechnical Pty Ltd within the area.
