Fig. 1. Relationships between loss rates of dissolved nutrients and rainfall intensities for all annual grassland rainfall simulations. (A) NH⁺₄, (B) NO^-₃, (C) solute organic N, (D) solute organic C. The R² values are from best fit regressions using power functions. Only the NO^-₃ data showed a significant (P < 0.05) relationship with intensity.
