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 …

Conventional analytical methods used to determine the most economical farmer-based harvest system and corresponding nutrient management strategy for producing switchgrass (Panicum virgatum L.) feedstock do not consider agronomic and subsequent economic problems associated with soil nutrient...
