Human alteration of the global nitrogen and phosphorus soil balances for the period 1970–2050 (2009, background): “Many authors use higher values for river total P export [Mackenzie et al., 2002; Ruttenberg, 2005; Smil, 2000].”
Reconsideration of the planetary boundary for phosphorus (2011, methodology): “Current mass of P in erodible soil is estimated by Smil ((Smil, 2000)) to be 50,000 Tg based on an assumption of an average of 0.”
Phosphorus demand for the 1970-2100 period: A scenario analysis of resource depletion (2010, background): “Finally, it should be noted that another consequence of the depletion of high-grade ores is the declining P content in ore and, associatedwith this, the increasing concentrations of heavymetals (Smil, 2000).”
Global Phosphorus Flows and Environmental Impacts from a Consumption Perspective (2008, background): “Soil losses, however, have been greatly increased by overgrazing, which now affects more than half (i.e., at least 1,720 million hectares) of the world’s permanent pastures, with a high erosion rate of 15 t/ha each year (Smil 2000).”
Bacteria and fungi can contribute to nutrients bioavailability and aggregate formation in degraded soils. (2016, neutral): “Phosphorus (P) is another essential and growth-limiting nutrient in agro-ecosystems (Smil, 2000).”
Approaching a dynamic view on the availability of mineral resources: What we may learn from the case of phosphorus? (2013, background): “There is evidence that the average human individual digests less than 3 g P per day (Uribarri and Calvo, 2001; Smil, 2000; Smit et al., 2009).”
Impacts of Nitrogen and Phosphorus: From Genomes to Natural Ecosystems and Agriculture (2017, background): “When applied at excessive levels, however, N and P may be lost via leaching, runoff, and erosion (e.g., globally, an estimated 15 million tons of P are lost annually from crop fields due to erosion; Smil, 2000), and an estimated 8 million tons of P are lost in runoff from arable land annually (Corde”
Luxury phosphorus uptake in microalgae (2019, background): “More detailed accounts of the problem of sustainable use of P and its social and economic implications can be found elsewhere (Smil 2000; Cordell et al. 2009, 2011; Cordell and White 2014; Daneshgar et al. 2018).”
Peak Phosphorus: Clarifying the Key Issues of a Vigorous Debate about Long-Term Phosphorus Security (2011, background): “While Smil estimated global food losses in the commodity chain at approximately 50% [55], Lundqvist et al.”
Food security and sustainable resource management (2015, background): “Although mineral reserves are uncertain, some researchers believe that the sources of mineral phosphorous of acceptable quality could essentially disappear before the end of the 21st century [Smil, 2000; Cordell et al., 2009].”
Life's Bottleneck: Sustaining the World's Phosphorus for a Food Secure Future (2014, background): “Several global phosphorus flow analyses have been undertaken in recent years, with some focusing more on phosphorus fluxes within the food system (5, 20, 21) and others having a greater emphasis on phosphorus fluxes from the food or agricultural system to the world’s oceans and fresh water bodies (1”
