This project will continue scheduled fertilization, foliar sampling, leaf area development, and re-measurement of nine, previously established 'maximum productivity' fertilization research installations on representative sites in major biogeoclimatic zones throughout the B.C. interior. Proposed research activities will provide reliable estimates of productivity gains potentially achievable by various rates and frequencies of repeated fertilization in interior managed forests. By so doing, the extent to which intensive fertilization can be depended upon to sustain or increase harvest levels and mitigate future timber supply shortfalls may be realistically evaluated. In collaboration with a multi-disciplinary team of scientists, ancillary studies will also be undertaken in selected 'maximum productivity' installations to document the effects of repeated fertilization on weevil/spruce interactions, soil biota activity and diversity, and soil physical and chemical properties. The results from these ancillary studies will reduce uncertainty regarding the long-term effects of intensive fertilization on ecosystem health and sustainability
