Treatment (TRT): 0 = true control (no N-fertilizer or micronutrients added), 1 = 0 g·N·m<sup>-2</sup>·yr<sup>-1</sup> + micronutrients, 2 = 1.02 g·N·m<sup>-2</sup> yr<sup>-1</sup> + micronutrients, 5 = 5.44 g·N·m<sup>-2</sup> yr<sup>-1</sup> + micronutrients, 8 = 27.2 g N·m<sup>-2</sup>·yr<sup>-1</sup> + micronutrients. CV = coefficient of variation, sum = summer, spr = spring, win = winter, PPT = precipitation, TEMP = temperature, t_1 = season preceding growing season (spring and summer) when plants were sampled. Ecologically meaningful models (EMMs) were those with DAICC < 2 and <i>R</i>² > 0.30. Model # corresponds to a priori models as described in <a href="appendix-B.php">Appendix B</a>. </p> </div>
