The interaction effect means within a column followed by the same letter are not significantly different from each other at . HG, home garden; GL, grazing land; CL, cultivated land; EP, Eucalyptus plantation; LSD, least significance difference; CV, coefficient of variation; SOM, soil organic matter; TN, total nitrogen; Av. P, available phosphorus; CEC, cation exchange capacity; BS, base saturation percentage; N, number of samples.
