|Table 5: Soil quality indices developed using a PCA selected dataset to compare eight LUSMS in the Mai-Negus catchment of northern Ethiopia.|
|Means followed by different letters in the same column are significantly different at ; LSD: least significance difference.|
Details of LSF and NLSF descriptions can be found in Section 2.4 (Step 2).
This shows overall mean of the different scoring and indexing methods across the columns for the same LUSMS as tested statistically.
LSF: linear scoring function; NLSF: nonlinear scoring function; IL: Liebig method LSF; IIL: Homothetic transformation method of LSF; IIIL: Glover method LSF; IN: CurveExpert method NLSF; IIN: Glover method NLSF; LUSMS: land use and soil management systems; SQI: soil quality index; PCA: principal component analysis; LS1: natural forest (reference); LS2: plantation of protected area; LS3: pasture land system; LS4: teff-faba bean rotation; LS5: teff-barley/wheat rotation; LS6: teff-monocropping; LS7: Maize monocropping; LS8: uncultivated-marginal land soil system.
