Our study also did not identify any significant
differences in SMBN between individual agroforestry
systems and pastures (data not shown) and pooled
comparisons further revealed no significant differences
(Table 4). The C/N ratio of soil microbial
biomass was similar for all treatments, averaging
8.7 and 8.6 for agroforestry plots and pasture, respectively,
in the upper 5 cm of soil.
