Abstract
Morelet var. hondurensis Barr. and Golf. stand in the northern Guinea savanna of Nigeria. Using an allometric regression of dry weight of tree components on stem diameter, the total 10-yr dry matter production was estimated to be 133700 kg ha-' excluding losses due to pruning operation. The bole material represented the greatest proportion of the tree standing biomass (about 58%) followed by roots (19%), needles (13%), and branches (10%). Nutrient concentrations were highest in the foliage and lowest in the wood. Nutrient content determination showed that the stand contained 426, 30, 188, 271 and 81 kg ha-' of N, P, K, Ca and Mg, respectively. Estimates were made of nutrient removals to be expected by harvesting the stand in different ways. Nutrient removals were highest in the total tree above ground harvest in which 311, 23, 156, 64 and 47 kg ha-' of N, P, K, Ca and Mg respectively were removed. Comparison of nutrient removals in the different harvesting systems with estimates of nutrient pool of the upper 30 cm of the mineral soil showed that the respective soil nutrient pools generally exceeded those sequestered in the stand biomass; the only exception being P for which the soil pool was less than removal in total tree above ground harvest.
