Fig. 4: Effects of P addition, either alone or combined with N addition, on soil enzymatic stoichiometries and vector length of different ecosystems.

Values are expressed as meansâ±â95% confidence intervals (CIs). The scatters indicate the effect value of the original data. If 95% CIs did not overlap zero, the nutrient addition effect was considered significant. Ns indicates nutrient addition had no significant effect on enzymatic stoichiometries and vector length. EE C:N: enzyme C:N ratio; EE C:P: enzyme C:P ratio; EE N:P: enzyme N:P ratio.
