TLDR
The paper shows that the amounts of P applied in agriculture could be considerably smaller by optimizing land use, improvement of fertilizer recommendations and application techniques, modified livestock diets, and adjustment of livestock densities to available land.About:

Towards global phosphorus security: A systems framework for phosphorus recovery and reuse options
TL;DR: This paper examines the full spectrum of sustainable phosphorus recovery and reuse options (from small-scale low-cost to large-scale high-tech), facilitates integrated decision-making and identifies future opportunities and challenges for achieving global phosphorus security.
Journal ArticleDOI
How Circular is the Global Economy?: An Assessment of Material Flows, Waste Production, and Recycling in the European Union and the World in 2005
TL;DR: In this paper, the authors applied a sociometabolic approach to assess the circularity of global material flows and found that only 4 gigatonnes per year (Gt/yr) of waste materials are recycled in the EU and only 1.5% of processed materials are used to provide energy and are thus not available for recycling.

Transition towards Circular Economy in the Food System
Alexandra Jurgilevich,Traci Birge,Johanna Kentala-Lehtonen,Kaisa Korhonen-Kurki,Janna Pietikäinen,Laura Saikku,Hanna Schösler +6 more
TL;DR: In this article, the authors apply the concept of circular economy to the case of a sustainable food system and explore the transition towards a circular food system through the lens of socio-technical transition theory towards sustainability.

Life's Bottleneck: Sustaining the World's Phosphorus for a Food Secure Future
Dana Cordell,Stuart White +1 more
TL;DR: The authors provides an updated and integrated synthesis of the biophysical, social, geopolitical, and institutional challenges and opportunities for food security, and provides an overview of the current state of the phosphate supply chain.

The Relevance of Phosphorus and Iron Chemistry to the Recovery of Phosphorus from Wastewater: A Review
Philipp Wilfert,Prashanth Suresh Kumar,Leon Korving,Geert-Jan Witkamp,Mark C.M. van Loosdrecht +4 more
TL;DR: It is suggested that the current poor understanding of iron and phosphorus chemistry in wastewater systems is preventing processes being developed to recover phosphorus from iron-phosphorus rich wastes like municipal wastewater sludge.

The story of phosphorus: Global food security and food for thought
TL;DR: In this article, the authors put forward the case for including long-term phosphorus scarcity on the priority agenda for global food security, and presented opportunities for recovering phosphorus and reducing demand together with institutional challenges.
Book
Treatise on geochemistry
TL;DR: This extensively updated new edition of the widely acclaimed Treatise on Geochemistry has increased its coverage beyond the wide range of geochemical subject areas in the first edition, with five new volumes which include: the history of the atmosphere, geochemistry of mineral deposits, archaeology and anthropology, organic geochemistry and analytical geochemistry as discussed by the authors.
Journal ArticleDOI
The role of phosphorus in the eutrophication of receiving waters: a review
TL;DR: It is best to measure and regulate total P inputs to whole aquatic ecosystems, but for an easy assay it is hest to measure total P concentrations, induding particulate P, in surface waters or NIP atomic ratios in phytoplankton.
Journal ArticleDOI
PHOSPHORUS IN THE ENVIRONMENT: Natural Flows and Human Interferences
TL;DR: In this article, the global mobilization of the element, a part of the grand geotectonic denudation-uplift cycle, is slow and low solubility of phosphates and their rapid transformation to insoluble forms make the element commonly the growth-limiting nutrient, particularly in aquatic ecosystems.
Journal ArticleDOI
Is there a critical level of organic matter in the agricultural soils of temperate regions: a review
P Loveland,J. Webb +1 more
TL;DR: In this paper, a review summarises what is known about critical thresholds of soil organic carbon (SOM) or SOM, mainly in soils of temperate regions, and their potential effects on soil quality, soil physical properties and crop nutrition, and the links between these.
