Soft rock phosphate, or colloidal phosphate, is a natural, untreated, vegetarian source of long-lasting phosphate and soil building calcium. Rock phosphate provides phosphate that remains available to plants across a wide pH range.
Phosphate rock Revolvy
Phosphorite, phosphate rock or rock phosphate is a non-detrital sedimentary rock which contains high amounts of phosphate minerals. The phosphate content of phosphorite (or grade of phosphate rock) varies strongly, from 4% to 20% phosphorus pentoxide (PO).

Phosphate All hopes rest on Morocco with 75% of remaining reserves. Posted on March 21, This rate could both diminish the Earth's phosphorus stores and upset phosphorus cycling. China is the world's largest producer of phosphate rock (48% of the world's supply in 2013).
Extraction of rare earth elements from upgraded phosphate
Phosphate rock is considered a secondary source of rare earth elements (REE), which are usually found in isomorphism substitution with Ca2 ion. It approximately assays 001-01% (100-1000 mg g-1).
Rock Phosphates in Agriculture Experimental Agriculture
Rock Phosphates in Agriculture. Because the phosphate content is less than that of concentrated soluble fertilizers, the cost of transporting rock phosphates, per unit of phosphorus, may not be economic. However, for acid and calcium deficient soils the larger amounts of calcium that rock phosphates supply may be an advantage
Down To Earth Rock Phosphate 5 lb (6/Cs) Dealzer
Soft rock phosphate, or colloidal phosphate, is a natural, untreated source of long-lasting phosphate and soil-building calcium. Phosphate will remain available across a wide pH range. For best availability, soft rock phosphate should be mixed into soil or compost prior to planting.

Nov 29, 2016The Desert Rock That Feeds the World. While there has been a plateau in meat consumption in places like the U.S., Europe, and Australia, he says, places like Southeast Asia and China are seeing skyrocketing rates, and meat requires relatively more phosphate for production.
Phosphorus cycle Lenntech
The phosphorus cycle is the slowest one of the matter cycles that are described here. Phosphorus is most commonly found in rock formations and ocean sediments as phosphate salts. Phosphate salts that are released from rocks through weathering usually dissolve in soil water and will be absorbed by plants.
Phosphate Rock jstor
amounts of phosphate rock. At certain times in the earth's history, however, large amounts of phosphate were depos ited as phosphate rock by processes that were long a mystery. In 1937 A. V. Kazakov of the U.S.S.R. advanced the hypothesis that marine phosphate rock is deposited in areas of upwelling ocean currents. Such currents
