Biplots of the principal component (PC) analysis of soil characteristics by fallow types (forest fallow, short fallow and cropping conditions) and sampling depths (0–10 cm and 10–20 cm). (a,b) Forest fallow, (c,d) short fallow, and (e,f) cropping fields with the two sampling depths (Depth 1, 0–10 cm; Depth 2, 10–20 cm). Tko, Typic Kandiudox; Tku, Typic Kandiudult; Rku, Rhodic Kandiudult; soil-pH, pH measured in soil suspension; soil-N, nitrogen content; soil-C, carbon content; soil-Mg, magnesium content; soil-Al, aluminium content; soil-K, potassium content; soil-Ca, calcium content; soil-Pi, inorganic phosphate content in soil.
