Erratum to: Nutr Cycl Agroecosyst (2007) 79:45–58 DOI 10.1007/s10705-007-9094-6
Author would like to change the first paragraph appearing after the section Nitrous oxide emission measurements on p. 51 as follows:
A cropping system effect on N2O–N emissions was found for two successive measurements taken after the second fertilization of the conventional plot. At the May gas sampling event, N2O–N emissions from the conventional cropping system (16.6 g N ha−1 day−1) were greater than fluxes from both the low-input (4.0 g N ha−1 day−1) and organic (no N2O–N flux) systems (p < 0.05; Fig. 4). Greater N2O–N fluxes were also observed in the conventional system (13.5 g N ha−1 day−1) than in the low-input (no N2O–N flux) and organic (1.1 g N ha−1 day−1) systems at the June sampling event (p < 0.05; Fig. 4). With a cumulative N2O–N emission of 484.2 g N Mg N−1 (normalized with the soil N level of the cropping system), the conventional rotation showed the highest cumulative flux of N2O–N in comparison to the low-input (235.8 g N Mg N−1) and organic (103.6 g N Mg N−1) systems. Although greater than the organic system, cumulative N2O-N fluxes from the conventional and low-input systems were not different (p<0.05; data not shown).
Author would also like to change Fig. 4 on page 53 to:
