Peak Phosphorus

Reserves of phosphate rock, the main source of phosphorus used in fertilizers, are running out. Few reports have examined the implications of the world's dwindling phosphorus supplies, but based on the data that are available, peak global phosphorus production likely occurred in 1989 (Dry and Anderson, 2007; Ward, 2008).

Using Rock Phosphate For Gardens

Jun 08, 2021Rock phosphate, or phosphorite, is mined from clay deposits that contain phosphorus and is used to make organic phosphate fertilizers that many gardeners utilize. In the past, rock phosphate was used alone as a fertilizer, but due to a lack in supply, as well as low concentration, most applied fertilizer is

Phosphate and How Florida Was Formed

Phosphate rock was first mined in England in 1847 for use as a fertilizer. It was in 1881 that Captain J. Francis LeBaron, of the Army Corps of Engineers, discovered Florida's treasure in black phosphate pebbles in the Peace River. A "hard rock" phosphate reserve in North Central Florida was discovered next.

How phosphate is mined and processed

rock phosphate can become soluble (and available to plants) either by chemical weathering or through the actions of certain types of plants. The solubility also depends on rock type and the pH of the soil; phosphorus is most soluble when contained in sedimentary rocks as opposed to igneous rock, and when soil pH is between 5.5 and 7.2.
