Different agricultural producers account for approximately 8% of greenhouse gases, which come primarily from livestock, agricultural soils, and the production of rice. The management of agricultural soils is responsible for about 50% of the nitrous oxide emissions. Natural soil structure is disturbed by tillage, animals, weather, and mobile sources. The soil is broken into smaller pieces which can then cause soil erosion and the smaller pieces also may become airborne. Livestock always produce methane as part of their digestive process. This is about 33% of the methane produced by agriculture. Manure storage produces methane and nitrous oxide and accounts for 15% of the total greenhouse gas emissions from agriculture in the United States. Rice cultivation produces methane, and burning crop residue produces methane and nitrous oxide. Two weather- related events have the potential to increase the concentration of PM10. They are high winds and stagnation of an air mass.
Best Practices for Agriculture (See endnote 25)
Note: Not all Best Practices will work equally well in all agricultural settings and for all agricultural categories such as tillage and harvest, non-cropland, and cropland. There are variations in wind, soils, moisture conditions, and management approaches.
