Fig. 5 Multifractal f() spectra along with soil property distribution maps and histograms for (a) P; (b) K; (c) organic matter, OM; (d) pH; (e) Ca; (f) Mg; and (g) cation exchange capacity, CEC. Maps were obtained by interpolating the experimental data using the inverse distance weighted interpolation procedure. Histogram classes correspond to map classes and were obtained by dividing the data range into 12 equal-sized intervals
