Abstract

Biomass and nutrient accumulation in young Prosopis juliflora at Mombasa, Kenya.

Abstract

Data are presented for 6-yr-old P. juliflora, grown for quarry reclamation, on: biomass of stems, large branches, small branches and leaves; ht.; and vol. of stems and large branches. All were calculated from regressions on based diam. Vol. was 209 m3/ha (stems), 75 m3/ha (large branches). Total biomass was 216 t/ha (77% in stems and large branches). Leaves plus small branches (22.6% of biomass) contained over 50% of the pool of nutrients N, P, K and Mg. Implications are discussed for site depletion as a result of total tree use for fuelwood and fodder.
