Fig. 3. Scatter plots of water content with depth for each subplot. Line represents linear regression models for the trend defined as a function of depth. Equations for the trends are _C = 0.069 + 0.019z for the control subplot (a correlation coefficient of r² = 0.48), _S = 0.127 + 0.013z for the standard subplot (r² = 0.25), and _H = 0.087 + 0.017z for the high subplot (r² = 0.36).
