Table 3 Variables included in optimal best subsets regression models of O&A horizon (R2 = 0.45) and profile total (R2 = 0.32) C stocks (P = 0.001 for each), based on soil pedon and GIS data

From: Land use change and forest management effects on soil carbon stocks in the Northeast U.S.

  1. Variables are sorted by their relative strength of influence (in terms of standardized slope coefficients) and color-coded to distinguish those that are positively (orange) vs. negatively (blue) related to C stocks. See Additional file 1: Table S4 for the complete list of variables included in the selection pool for this modeling procedure
