Foliar Nutrients of Six forest Tree Species Grown in Brown Hill Soils of Bangladesh

Abstract

In the present investigation, foliar concentrations of N, P, K, Ca, Mg, Fe, Mn and Zn in two indigenous- Dipterocarpus costatus Gaertn F. and Dipterocarpus turbinatus Gaertn F. and four exotic forest tree species. Acacia auriculiformis A. Cunn. Ex. Benth., Acacia mangium Willd., Eucalyptus camaldulensis Dehnh. and Pinus caribaea Morelet. var. hondurensis Barr. and Golf. were determined. There was high variability in foliar K, Ca and Mn but low in P concentrations among the species. Within species variability was generally less than that between species. Foliar nutrients were not found to be correlated with soil nutrient supply.
