why is important to mine iron and phosphates

Why Is Phosphorus Important in Soil? Phosphorus is an extremely stable element chemically. Fertilizer phosphorus does not go far from the application site due to its quick reaction to the soil. It rapidly binds to iron and aluminum in the soil, rendering it unavailable to plants, particularly when the soil pH is less than 5.0. (CaCl2).
