Nevada Statewide Greenhouse Gas Emissions Inventory and Projections

Nevada Statewide Greenhouse Gas Emissions Inventory and Projections, 1990 to 2030 organic fertilization, tilling practices and production of nitrogen-fixing crops) accounted for about 27 percent; and manure management accounted for about 14 percent of total emissions in the agriculture sector. While residue burning is practiced in Nevada, emissions from this activity were negligible.

Figure 8-2 shows the relative contributions of CH4 and N2O emissions of the agricultural sector in Nevada. CH4 is the main gas contributing to agricultural sector GHG emissions and this is because enteric fermentation leads to CH4 generation.
