Abstract

The biomass of a six-year-old plantation of Prosopis juliflora was determined using simple linear regressions of (y) the tree components: stem (over bark), large branches, small branches and leaves on (x), diameter at the base of the trees. Similar regressions were used to estimate height and volume produced by both stem and large branches. Macronutrient concentrations in the different tree components were determined and multiplied by the appropriate total dry weights to obtain total contents per hectare. The total stem volume (at age 6) was 209 m3/ha and large branch volume was 75 m3/ha. Total biomass was 216 tons/ha. Over 77% of the total biomass was accounted for by stem and large branches. Nevertheless, the leaves plus small branches (making 22.6% of the biomass) contained over 50% of the total pool of the individual nutrients N, P, K and Mg. The implications of this finding on site depletion due to total tree use as fuelwood and folder is discussed.
