This source is distinct from emissions of NH3 that arise from the application of fertilizer to crops (which are reported under 3Da1 and 3Da2a-c). * Since PM emissions from livestock production arise from buildings these are calculated and reported in 3B. There are four main sources of emissions from crop production and agricultural soils: fertilizer application (NH3); soil microbial processes (NO); crop processes (NH3 and NMVOCs); soil cultivation and crop harvesting (PM).
