LU = land use, LU1 = cultivated land (annual crop), LU2 = cultivated land (perennial crop), LU3 = grazing land, LU4 = forest land; CV = coefficient of variation, SD = standard deviation, and LSD = least significant difference. Means of a given variable with different letters within a column are significantly different at ().
