Table 4
Principal components (PC) and component loadings related to physical, chemical, and biochemical properties determined in the different soils.

TOC: total organic carbon; THC: total humic carbon; AHC: active humic carbon; TN: total nitrogen; EG: extracellular -glucosidase activity; TG: -glucosidase activity; WSC: water soluble carbon; DH-ase: dehydrogenase activity; B/E3s: benzene/toluene whole soil; N/Os: furfural/pyrrole whole soil. Var. Sp.: explained variance; Prp. Tot.: total proportionality. Variables with component loadings used to interpret the PCs; threshold level: 0.7. |
