quired 2 g of P extraction throughout the production chai n, and the lifecycle Puse efficiency (PUE) is much higher than those of the food production system in China, the United States and worldwide. The P supply chain also saw waste production of 2,369 Gg P in 2012, with only 20% of the wastes recycled. The current recycling activities, however, lock in P instead of recovering it, which ...
Human Inputs to the Phosphorus Cycle: Human influences on the phosphate cycle come mainly from the introduction and use of commercial synthetic fertilizers. The phosphate is obtained through mining of certain deposits of calcium phosphate called apatite. Huge quantities of sulfuric acid are used in the conversion of the phosphate rock into a fertilizer product called "super phosphate". Plants ...
