Buy Rock Phosphate in Bulk from Iran

Rock 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, it was used alone as a fertilizer, but due to a lack in supply, as well as low concentration, most applied fertilizer is processed.

Phosphate Rock

The mining of phosphate rock (mostly from marine phosphorite deposits) for use as agricultural fertilizer (F 72) increased dramatically in the latter half of the twentieth century. In addition to fertilizer use, deforestation, increased cultivation, and urban and industrial waste disposal all have enhanced phosphorus transport from terrestrial to aquatic systems, often with deleterious results.
