Land Limitations • Poor Agricultural Land (blanket bogs, gley soils) • Pinus spp proved to be the best performer on these soils • The performance of broadleaved species was unsatisfactory at most sites • Betula survived at many locations but gave an unenonomic yield SRF Meeting Oak Park
Trials on Harvested Peatland • Reasonable yields only obtained where there was at least 0.5m of peat remaining. Very poor yields obtained when plants were sown directly into calcareous marl • Salix and Populus proved to be the most promising species generally although there was considerable variation among species.
