Figures & data
Figure 1. Effect of steel making slag on methane emissions in paddy fields in Vietnam. The yield scale total CH4 emission (amount of total CH4 emission divided by rice yield) was calculated for each treatment, and the ratio (the yield scale CH4 emission from steel slag treated plot)/(the yield scale CH4 emission from control) was plotted in the Y-axis. Open bar □ indicates summer season, closed bar ■ indicates spring season
