• Biomass use, production, feed efficiencies, and greenhouse gas emissions from global livestock systems (2013, methodology): “Crop residue availability was estimated using the Spatial Production Allocation Model cropland layers (32) and applying coefficients of stover use for animal feeding and harvest indexes for different parts of the world (3, 50).”
• Mycorrhizal effects on nutrient cycling, nutrient leaching and N2O production in experimental grassland (2015, unknown): “In agriculture, huge amounts of chemical fertilizers are applied to fi elds, of which around 50% remain unused by crops and are prone to getting lost from the system (Smil, 1999; Liu et al., 2010).”
• The green, blue and grey water footprint of crops and derived crops products (2011, background): “Liu et al. (2010) estimated, for the first time, global nitrogen flows of 6 nitrogen inputs and 5 nitrogen outputs including nitrogen leaching at high resolution (5 by 5 arc minute grid).”
• A tradeoff frontier for global nitrogen use and cereal production (2014, methodology): “Nitrogen balance calculations are carried out using the approach of Foley et al [3], which builds on earlier nutrient balance work for both nitrogen [16, 29] and phosphorus [30].”
• Agriculture production as a major driver of the Earth system exceeding planetary boundaries (2017, unknown): “Liu et al. (2010), for example, found total N input to croplands in 2000 to be about 137 Mt N yr -1 , whereas Bouwman et al. (2009) estimated total agricultural N input at 249 Mt N yr -1 .”
