  1. All data are presented as the mean ± SD (standard deviation)
  2. H high N application in the sugarcane soil (964 kg ha−1), M medium N application in the sugarcane soil (482 kg ha−1), L low N application in the sugarcane soil (96 kg ha−1), CK no N application in the sugarcane soil (0 kg ha−1)
  3. Different letters in the same column indicate significant differences between treatments at P < 0.05 among the means of the four treatments
