Fig. 1: Relationships between N and P in the early-stage soil under natural conditions (without N or P addition, n = 90 plot replications per treatment).

The red line represents the linear regression between two variables, the red shaded region represents the 95% confidence band for the regression, and the light red shaded region represents the 95% prediction band for the regression. A Linear regression between available phosphorus (AP) and ammonium nitrogen (NH4+–N). B Linear regression between AP and nitrate nitrogen (NOx−–N). C Linear regression between AP and total phosphorus (TP). D Linear regression between total nitrogen (TN) and NH4+–N. E Linear regression between TN and NOx−–N. F Linear regression between TN and TP.
