Soil physical and chemical characteristics in three 1 ha plots of monodominant Gilbertiodendron forest and three 1 ha plots of mixed forest at Dja Faunal Reserve, Cameroon.

Top soil values were calculated by averaging values of the top depth classes: 0–5 cm, 5–10 cm, 10–20 cm and 20–30 cm. Deep soil were 150–200 cm. All values are expressed in mean ±95% confidence intervals (n = 3). Inorganic P and total P were extracted using NaOH. NS denotes there was non-significant difference between the two forest types based on the t test for matched paired comparison (n = 3). ns denotes the two forest types were insignificantly different.
