e6“The lowest nutrient uptake occurred in the scenario in which only the stem was removed, with averages of 44.17, 10.43, 21.93, 52.59 and 9.97 kg ha−1 for N, P, K, Ca and Mg, respectively”
e7“Compared to total biomass harvesting, this represents a reduction in export levels by 91.34% for N, 79.31% for P, 94.66% for K, 94.29% for Ca and 93.28% for Mg”

- Observation K. senegalensis had the highest bark percentage of biomass.
- Observation K. ivorensis had the highest leaf percentage of biomass.
- Observation Stem and branch biomass did not vary among Khaya species.
- Observation Relative biomass proportions followed the order branches > stems > bark > leaves.
- Association Ca stocks were higher in K. grandifoliola than in K. senegalensis, by 22.1%.
- Association Mg stocks were higher in K. grandifoliola than in K. ivorensis, by 42.3%.
