| Abstract |
The Application Of Phosphorus (P) Fertilizer To Agricultural Soils Increased By 3.2 % Annually From 2002 To 2010. We Quantified In Detail The P Inputs And Outputs Of Cropland And Pasture And The P Fluxes Through Human And Livestock Consumers Of Agricultural Products On Global, Regional, And National Scales From 2002 To 2010. Globally, Half Of The Total P Inputs Into Agricultural Systems Accumulated In Agricultural Soils During This Period, With The Rest Lost To Bodies Of Water Through Complex Flows. Global P Accumulation In Agricultural Soil Increased From 2002 To 2010 Despite Decreases In 2008 And 2009, And The P Accumulation Occurred Primarily In Cropland. Despite The Global Increase In Soil P, 32 % Of The World's Cropland And 43 % Of The Pasture Had Soil P Deficits. Increasing Soil P Deficits Were Found For African Cropland Vs. Increasing P Accumulation In Eastern Asia. European And North American Pasture Had A Soil P Deficit Because The Continuous Removal Of Biomass P By Grazing Exceeded P Inputs. International Trade Played A Significant Role In P Redistribution Among Countries Through The Flows Of P In Fertilizer And Food Among Countries. Based On Country-scale Budgets And Trends We Propose Policy Options To Potentially Mitigate Regional P Imbalances In Agricultural Soils, Particularly By Optimizing The Use Of Phosphate Fertilizer And The Recycling Of Waste P. The Trend Of The Increasing Consumption Of Livestock Products Will Require More P Inputs To The Agricultural System, Implying A Low P-use Efficiency And Aggravating P-stock Scarcity In The Future. The Global And Regional Phosphorus Budgets And Their Pues In Agricultural Systems Are Publicly Available At Https://doi.pangaea.de/10.1594/pangaea.875296. |
