Factors Controlling Carbon Metabolism and Humification in Different Soil Agroecosystems

Figure 1

Biplot of factor scores and loadings at each sampling time (T1 and T2), in each treatment. TOC: total organic carbon; THC: total extractable carbon; AHC: extractable carbon fraction >10.000 Da; TN: total nitrogen; EG: extracellular -glucosidase activity; TG: -glucosidase activity; WSC: water soluble carbon; DH-ase: dehydrogenase activity; B/E3s: benzene/toluene whole soil; and N/Os: furfural/pyrrole whole soil.
