The interaction effects within a column followed by the same letter are not significantly different from each other at . CL, cultivated land; HG, home garden; GL, grazing land; EP, Eucalyptus plantation; KCl, potassium chloride; AS, acid saturation percentage; LSD, least significance difference; CV, coefficient of variation; EA, exchangeable acidity; N, number of samples.
