Table 3. Results for soil samples taken inside and outside canopies at sites in the Falealupo Rain Forest Preserve, Samoa, that burned in 1993 (n = 7) and 1998 (n = 6). The samples were analyzed for moisture factor (MF) or percentage water content of the soil, the pH of the water contained in the soil, and total nitrogen (N), NH4OAc-extractable calcium (Ca), magnesium (Mg), potassium (K), and Truog phosphorus (P) expressed as grams per kilogram of soil.
