Total C peaks identified in soil pore waters by soil homogenization, antecedent drought and wetting direction. The total number of Fourier-transform ion cyclotron resonance (FT-ICR) mass spectrometry peaks of organic C identified across all pore water fractions that significantly differed by a soil homogenization (P = 0.001, n = 43 for intact, 42 for homogenized), b antecedent drought (P = 0.011 l, n = 46 for field moisture, 39 for antecedent drought), and c wetting direction (P = 0.034, n = 44 for simulated precipitation, 41 for simulated groundwater rise). The outlier box plot whiskers represent the first and third quartile minus or plus, respectively, 1.5 times the interquartile range. Soil pore water was collected immediately following rewetting and post-rewetting incubation
