Means in the same column followed by the same letter(s) are not significantly different at 5% level of significance, LSD = least significant difference, CV = coefficient variation, US = upper slope, MS = middle slope, LS = lower slope, OC = organic carbon, TN = total nitrogen, Av. P = available phosphorus, PBS = percentage base saturation.
