Stems and leaves were harvested in the SC field. Litterfall was collected in the MG plantation using circular litter-traps (60 cm in diameter). Fine root biomass in the mineral soil was estimated by collecting the roots at 5-cm depth intervals in cores of 0.1-L volume. Five replicates were used for these measurements. The aboveground biomass of the mango trees was estimated by measuring the diameters and lengths of tree stems. Wood increment was estimated from the aboveground biomass produc-tion in a 10-year-old plantation. Wood samples were collected using an increment borer. Plant samples were oven-dried at 70 C for 48 h, weighed, and milled. The mineral fertilizer samples were collected (n = 3) and oven-dried at 105 C prior to chemical analyses. The C and N concentrations in plant and fertilizer samples were determined using a CN analyzer. The Na and K concentrations in plant and fertilizer samples were determined by flame photometry and Mg and Ca concentrations were determined by atomic absorption spectroscopy after nitric-sulfuric acid wet digestion.
