Matrix is a mixture of phosphate rock, sand, and clay. Once the phosphate rock is extracted from the matrix, it is turned into a slurry mixture and sent to manufacturing plants for processing. A typical Florida phosphate mine gets about 9,000 tons of phosphate rock per acre of land
World Phosphate Rock Reserves and Resources Executive Summary The amount of remaining phosphate rock reserves and resources worldwide has become an issue of speculation. It has been hypothesized that phosphorus (phosphate rock) production will "peak" in 2033-2034 and then production will unavoidably decrease as the reserves are depleted.
When phosphate rock is added to soil, it slowly dissolves to gradually release nutrients, but the rate of dissolution may be too slow to support healthy plant growth in some soils. To optimize the effectiveness of phosphate rock, consider these factors: Soil pH. phosphate rock requires acid soil conditions to effectively nourish crops.
