Agricultural activities contribute to emission and removal of greenhouse gases through many processes. This report assesses emissions of methane (CH4) and nitrous oxide (N2O) from enteric fermentation in domestic livestock, livestock manure management, agricultural soil management, and net emission of carbon dioxide (CO2) from changes in land use across all land types within the NYS border, including effects of management of agricultural soils and grasslands, liming, and urea fertilization. Greenhouse gas emissions from stationary and mobile on-farm energy use are reported in the Energy sector emissions.
