Agriculture is the main source of nitrogen loading (EEA, 2012) and is the sector with the largest remaining emission … reduction potential (Sutton et al., 2011). Furthermore, surpluses of nitrogen are forecast to grow in the next decade (FAO, 2008 …). The objective of this study is to evaluate the determinants of the use of nitrogen inputs in agriculture, and the effects …

The rapid growth in fertilizer consumption throughout the sixties and seventies peaked at 23.7 million nutrient tons in 19R1. U.S. plant nutrient use has since dropped by varying amounts because of fewer crop acres and stabilizing application rates. By 19R,), plant nutrient use totaled 21.7...

The rapid growth in fertilizer consumption throughout the sixties and seventies peaked at 23.7 million nutrient tons in 1981. After falling to 18.1 million tons in 1983, use has remained relatively stable, ranging from 19.1 to 21.8 million tons during 1984-93. Use has declined from its peak...
