Relationships between soil total sulfur (STS) and soil relevant components in drying-affected soils studied, showing that low levels of STS are associated with high levels of these components, and conversely, high levels of STS correspond to low levels of the relevant soil components. The relationships shown include STS with SOC (a), SIC (b), STN (c), STH (d), DOCLS+CS (e), DICLS+CS (f), SiO32-LS+CS (g), NH4 + LS+CS (h), NO2-LS+CS (i), PO43-LS+CS (j), and DOPLS+CS (k). Pearson correlation of STS with NO3-LS+CS (l) in drying-affected soils studied. The significance of the p-values are at the level p < 0.01 or p < 0.001.
