  1. Four replicates (n = 4) per site were used. C, carbon; N, nitrogen; Pi, phosphate; Mg, magnesium; Al, aluminum; K, potassium; Ca, calcium. Numbers followed by different small letters within a column are significantly different (p < 0.05) in comparing the fallow types (forest fallow, short fallow and cropping conditions) within a sampling depth of each soil origin. Numbers followed by different capital letters within a row are significantly different (p < 0.05) in comparing the two soil depths (0–10 cm and 10–20 cm) in all three soil origins (Tko, Typic Kandiudox; Tku, Typic Kandiudult; Rku, Rhodic Kandiudult).
