Air, with all its inclusions, forms the earth's atmosphere. Concerns such as acid rain, global change, and ozone depletion are potential consequences of the use of air as a global dumping ground. Agriculture is not free of guilt concerning degradation of the air resource. The Natural Resources Conservation Service recognizes two considerations of the air resource. Quality is a measure of the concentration of particulates and gases relative to an accepted standard which limits the use of the air for a designated purpose at a specific location.
Condition is the inherent physical characteristics of the air.
Odors, gases, smoke and dust from agricultural activities cause air quality problems. Conservation practices can alter air movement, temperature and humidity. Odors from animal waste, and gases resulting from chemical applications, can drift into populated areas. Windbreaks can reduce air movement, and affect air temperature and humidity. Recognized agricultural practices can be used to reduce detrimental effects from agriculture on the air resource.
