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.
Air quality is changed when some type of contaminant is introduced into the air.
Examples could be automobile exhaust, dust from wind erosion, and odor from a cattle yard, or any activity or occurrence that puts particles, liquids, or gases into air. Air condition is changed when some activity or occurrence changes air temperature, humidity, or movement. You change the air condition in your car when you run the air conditioner or roll down the window. In agriculture, we can change air condition by installing wind breaks, putting blankets on flowers to protect them from frost, or run a grain bin dryer. When inhaled, each of these pollutants have been shown to have deleterious effects on human health.
