Corrections to denitrification measurements in Ochs and Milburn (2003), with a revised view of the importance of denitrification to N-loss from agricultural soils of the Mississippi Delta.

Article Excerpt
In our evaluation of the effects of wintertime flooding on nitrogen and phosphorus cycling in soils from the Mississippi Delta (Ochs and Milburn 2003), we report data for denitrification rates in flooded and non-flooded agricultural soil cores. The results for denitrification shown in FIGURE 4a and 4b were reported in units of mg [N.sub.2]O-N [ha-.sup.-1] [day.sup.-1]. This was an error. The correct units for denitrification in this FIGURE should be grams [N.sub.2]O-N [ha.sup.-1] [day.sup.-1] (see FIGURE 4a and 4b revised).

With this correction, we re-evaluate the importance of denitrification in this study. In Table 2 of the original study (Ochs and Milburn 2003) we provided estimates for the percent losses of nitrogen, relative to ambient total N pools, in cotton and soybean fields over the course of a 90-day winter period. In Table 2-revised, we...
