Phosphate rock (PR) is a finite mineral indispensable for fertilizer production, while P (phosphorus) is a major pollutant if applied or discharged in excess, causing widespread eutrophication (Carpenter and Bennet, 2011). High-grade PR is obtained from deposits which took millions of years to form and which are gradually being depleted. Recently, global PR reserves as reported by the US Geological Survey (USGS) have increased from 16 000 Mt PR in 2010 to 65 000 Mt PR in 2011 and further to 67…

Depletion of phosphate rock reserves and world food crisis: Reality or hoax?

Phosphate rock (PR) deposits are the major source of phosphate (P) fertilizers for soil fertility replenishment. The demand for P fertilizers in the year 2014 was 42,706,000 tons and was expected to

Impact of Mineral P Fertilization on Trace Elements in Cropland Soils

Phosphorus (P) is indispensable for crop production, and mineral fertilizers processed from rock phosphates, such as superphosphates, represent an important P source. In the past, P fertilizers from

Comment on: "Recent revisions of phosphate rock reserves and resources: a critique" by Edixhoven et al. (2014) – Phosphate reserves and resources: what conceptions and data do stakeholders need for sustainable action?

Several recent papers deal with concerns about the longevity of the supply of the mineral phosphorus. The paper by Edixhoven et al. (2014), for instance, expresses doubts about whether the upward

Phosphorus Recovery from Wastewater: Bioavailability of P Bound to Calcareous Material for Maize (Zea Mays L.) Growth

(1) Phosphorus (P) is an essential plant nutrient, and P deficiency negatively affects plant growth and development. Furthermore, P is a finite and nonrenewable resource, and there is an urgent need

Regional phosphorus management in Berlin-Brandenburg

Phosphorus (P) is a virtually finite nutrient element that cannot be substituted by any other substance. To overcome limited supply of mineral P deposits and to contribute to its sustainable

Phosphate Rocks and Nuclear Proliferation

ABSTRACT Phosphate rocks are predominantly mined for fertilizer production. However, they also contain considerable amounts of accompanying natural uranium that can exceed concentrations found at

Comment on: "Recent revisions of phosphate rock reserves and resources: a critique" by Edixhoven et al. (2014) – clarifying comments and thoughts on key conceptions, conclusions and interpretation to allow for sustainable action

It is concluded that there is no evidence for considering the somewhat surprising increase to 50 Gt phosphate concentrate to be an unreasonable estimate for Moroccan reserves and the establishment of a solidly funded, international standing committee that regularly analyzes global geopotential for assuring long-term supply security is suggested.

Residual soil phosphorus as the missing piece in the global phosphorus crisis puzzle

A two-pool soil P model is applied to reproduce historical continental crop P uptake as a function of P inputs from fertilizer and manure and to estimate P requirements for crop production in 2050, which is up to 50% less than other estimates in the literature that ignore the role of residual soil P.
