Get MoreEnriched Rock Phosphate. Rock phosphate, also known as phosphorite, is a sedimentary rock with a high phosphorus content by weight. At 17 to 30% phosphorus by weight, enriched rock phosphate is one of the best sources of phosphate for growing crops. Rock phosphate is often found in limestone and other sedimentary rocks.

Get MorePHOSPHATE ROCK (Data in thousand metric tons unless otherwise noted) Domestic Production and Use: In 2020, phosphate rock ore was mined by five firms at 10 mines in four States and processed into an estimated 24 million tons of marketable product, valued at $1.7 billion, free on board (f.o.b.) mine.
Get MorePhosphorus fertilizers are manufactured from rock phosphate (Figure 2.2 ), but rock phosphate itself seldom is used directly as a fertilizer because of its low availability of phosphorus and transport cost. Instead, finely ground rock phosphate is treated with sulfuric acid to yield monocalcium phosphate monohydrate and is known as superphosphate.
Get MoreIn the phosphate industry, the phosphate content of the rock is usually expressed as tricalcium phosphate and traditionally referred to as bone phosphate of lime (P 2 O 5 × 2.1853 = BPL). The latter term is reminiscent of the time when bones were the principal source of phosphate in the fertilizer industry.
Get MoreWhat Does Rock Phosphate Do for Plants? These fertilizers are commonly called "rock dust" and provide just the right amount of nutrients to make plants strong and healthy. The use of rock phosphate for gardens is a common practice for both flowers as well as vegetables. Flowers love an application of rock phosphate early in the season and ...
Get MoreOnce applied, rock phosphate remains in the soil until used by the plants – will not leach. Ideal for fruiting and flowering plants, it stimulates strong root formation, hastens crop maturity and encourages earthworms and soil bacteria. Benefits: • A non-leachable source of phosphorus and calcium • Used by growers for over 50 years
Get MoreThe main phosphate rock deposits are either sedimentary or igneous, each with different mineralogical, structural, and chemical properties (Van Enk et al., 2011). Marine sedimentary deposits account for 80% of the global phosphate rock production, with large producers such as China, Morocco, U.S. and Tunisia.
Get MoreGranulated Guano Phosphate Rock is a slow release natural form of phosphorus containing 9.4% phosphorous of which 50.5% is readily available (50.5% citrate solubility), with the balance released over 3 to 5 years. .

Get MorePhosphorus is one of the major macro elements required for plant growth. Farmers can source and apply phosphorous to phosphate deficient farm land using a variety of commercial processed phosphate fertilizers or in its more natural form as rock phosphate powder or as a rock phosphate granular product alone or in a blend with other nutrients.
Get MoreChemical Processing of Phosphate. The phosphate mineral as it exists in the ground is not soluble and is hard for the plant to access. To provide the plant with the phosphate it needs, in a form it can take up through its roots, the phosphate rock is converted to phosphoric acid. It is that acid that is used to make fertilizer.
Get MoreEspoma Rock Phosphate Plant Food is designed for organic gardening which helps boost root development. It contains just the right amount of Phosphorous, an essential nutrient that all flowering plants need to ensure maximum growth and promote healthier blooms.
Get MoreA 1971 study of the phosphate industry in Maury County reported that the three phosphorus producing plants had an annual payroll of $15 million. An additional $60 million to $70 million were put into the local economy that year in the purchasing of raw materials and in the operating and maintaining of material and supplies.
