Geoderma 271, 173–180. 306-7 Metallurgy Slag As Soil Acidity Amendment and Tolerance to Drought Stress in Development of Forages. Iron oxidation coupled to denitrification can occur in anoxic soils, which can lead to N2O production (Melton et al., 2014); however, under conditions where Fe is highly available, the electrons donated by Fe(II) exceed the electron demand for N2O production, which leads to complete denitrification to N2 and thus a suppression of N2O emissions (Wang et al., 2016). The main concerns regarding the use of slag in agriculture are the potential for heavy metal accumulation in soil and the risks related to liming of soil (Chand et al., 2015). In Figure 1, we show the proposed mechanism of slag-microbe interactions in soil.
