Abstract: A nutritional study of wild frankincense (Boswellia sacra) trees and soils was undertaken in the Dhofar Region of Oman to identify causes for variations in resin quality. Trees with different growth habits were sampled from regions varying in monsoon rainfall and soil type. Composite leaf and soil samples were chemically analysed from 6 locations. Trees appeared to favour gravelly and calcareous soil conditions. Soil and leaf analysis supported the hypothesis that highest resin quality was associated with trees deficient in N, P, K but relatively high in Na. Poorer quality resin was found in nutritionally less stressed trees. The difficulties in duplicating the combination of stresses that trees suffer may be a reason why cultivation of high quality frankincense has rarely been achieved in Oman.
