...Nice article with some great take-home messages!<br /><br />I'd like to add one more: atmospheric deposition of nitrogen can be a significant source of nitrogen pollution to coastal waterways. In the Chesapeake Bay watershed, for example, up to 40% of nitrogen loads are from deposition of airborne nitogen sources. Nitrogen gets into the air from combustion of coal, natural gas, gasoline and diesel fuel. Thus, reduced nutrient pollution and hypoxia is another benefit of driving fewer miles, mowing our lawns less often, and using less electricity. http://www.epa.gov/airquality/gr8water/xbrochure/chesapea.html<br /><br />My next comment is a bit of a tangent but might be of interest to some: something to keep an eye on is that the recent natural gas production boom could result in increased synthetic (ammonia-nitrogen) fertilizer use. Most of the cost of ammonia production is in natural gas; the hydrocarbons are actually used as an ingredient as well as fuel. Because natural gas prices are currently so low, it has become much cheaper to produce nitrogen fertilizer. <br /><br />http://minnesota.publicradio.org/collections/special/columns/statewide/archive/2013/05/new-fertilizer-plant-in-north-dakota-could-help-farmers.shtml<br /><br />http://news.yahoo.com/fertilizer-plants-spring-advantage-u-cheap-natural-gas-121500314.htmlAnonymoushttps://www.blogger.com/profile/06816692355634925151noreply@blogger.com
