Table 3 Results of the three-way ANOVA testing the differential effects of fallow types (F, three levels; forest fallow, short fallow and cropping conditions), soil origins (S, three levels; Typic Kandiudox, Typic Kandiudult and Rhodic Kandiudult), sampling depths (D, two levels; 0–10 cm and 10–20 cm), and their interactions on the arbuscular mycorrhizal species abundance distribution, species richness, Shannon-Weaver (S-W) diversity index and spore number.
