Des recherches approfondies sur le potentiel agronomique et l'efficacité des phosphates naturels (PN) comme source de phosphore ont été effectuées notamment en Afrique, en Asie et en Amérique Latine. Beaucoup d'informations sont disponibles mais elles sont dispersées dans divers rapports et publications. Ce bulletin reprend de façon détaillée les principaux thèmes concernant l ...
Phosphorus is an essential element for plant and animal nutrition. Most phosphorus is consumed as a principal component of nitrogen-phosphorus-potassium fertilizers used on food crops throughout the world. Phosphate rock minerals are the only significant global resources of phosphorus. The United States is the world's leading producer and consumer of phosphate rock, which is
The OCP Group (OCP S.A.) (formerly Office Chérifien des Phosphates) is a Moroccan based phosphate rock miner, phosphoric acid manufacturer and phosphate fertilizer producer. Founded in 1920, the company has grown into one of the world's largest producers of phosphate and phosphate-based products. OCP has access to more than 70% of the world's phosphate rock reserves.
Le phosphate dans le Monde Le commerce mondial du phosphate et de ses dérivés a connu un redressement sensible en 2004 puisqu'il a augmenté de 5.5% par rapport à 2003. Les Etats unis, la chine, le Maroc et la Russie restent les principaux producteurs de phosphate dans le monde. La hausse enregistrée en 2003 déjà est due
Monopotassium phosphate, MKP, (also potassium dihydrogenphosphate, KDP, or monobasic potassium phosphate), KH2PO4, is a soluble salt of potassium and the dihydrogen phosphate ion. It is a source of phosphorus and potassium as well as a buffering agent. It can be used in fertilizer mixtures to reduce escape of ammonia by keeping pH low.

Mélanges de soufre élémentaire et de phosphate naturel. De nombreuses études ont montré que l'efficacité agronomique des PN peut être améliorée quand ils sont appliqués après avoir été mélangés ou cogranulés avec du soufre (S). Parfois, les produits étaient inoculés avec des bactéries oxydant le soufre Thiobacillus spp. Ainsi ...

Calcium Phosphate is the calcium salt of phosphoric acid with widely used applications. This agent can be used as a countermeasure for exposure to strontium and radium radionuclides. Upon oral uptake, calcium phosphate competes for and blocks the absorption of radium (Ra-226) and strontium in the gastrointestinal (GI) tract.
