Erratum: Evaluation of intensive "4R" strategies for decreasing nitrous oxide emissions and nitrogen surplus in rainfed corn [J. Environ. Qual., 45, 4, (1186-1195)] DOI: 10.2134/jeq2016.01.0024

In the "Materials and Methods" section (p. 1188) and in Table 3 (p. 1193), the units for soil nitrogen (N) intensity are incorrectly listed as mg N kg ^-1 d ^-1 . The correct units, corresponding to the values reported in Table 3, are g N kg ^-1 d, which can be alternatively written as g N d kg ^-1 . These units were obtained by trapezoidal integration of soil N concentrations (in mg N kg ^-1 ) versus time (in days) followed by division by 1000 mg g ^-1 . Table 3 is reproduced below, with the corrected units.
