Recent revisions of phosphate rock reserves and resources: a critique
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 Geolog...
متن کاملEffect of Hydrochloric Acid on Leaching Behavior of Calcareous Phosphorites
The bulk of the world's phosphate reserves is located in sedimentary horizons that contain appreciable amounts of carbonate. During beneficiation of phosphate rocks, huge amounts of oversize phosphate rocks are rejected from crushers. This reject also mostly contains low tricalcium phosphate and high carbonate content. In this study, experiments have been carried out to reduce/eliminate car...
متن کاملIdentification and Evaluation of Unconventional Hydrocarbon Reserves: Examples from Zagros and Central Iran Basins
It is notable that over the past decade, proven reserves of natural gas have dramatically increased as higher prices and advances in technology have turned previously unrecoverable resources into major sources of domestic production. Moreover, the decline in crude oil reserves has significantly slowed over the past decade. Therefore, there would be an end to the conventional hydrocarbon resourc...
متن کاملPhosphate deprivation in maize: genetics and genomics.
Plants acquire phosphorus (P) from the soil in order to reach the intracellular concentrations necessary for growth and reproduction. To prevent P starvation, both monocotyledonous and dicotyledonous plants have evolved well-regulated systems for inorganic phosphate (Pi) scavenging, acquisition, and recycling. Phosphate starvation responses (PSR) in plants include release of organic acids and h...
متن کاملAgrogeology: An interdisciplinary approach to serve agricultural development
Agrogeology is a relatively new applied, problem-solving, interdisciplinary earth and agricultural science that aims at improving agricultural production using agromineral resources. There are two aspects of agrogeology: 1. The influence of parent material on soil development and soil fertility, and 2. The beneficial application of rocks and minerals to enhance soil fertility and crop productiv...
