Environmental Constraints - Agricultural Production



Current practices in US agriculture intensively use fertilizers, which contribute to eutrophication of our freshwater sources, harming aquatic ecosystems.  To put US fertilizer use in perspective, the US is second to China as a top consumer of nutrients (including Nitrogen, Phosphate and Potash fertilizers), using an average of 6.6 million tonnes of nutrients from 2002-2007 (see Figure 1 below).
