At Rock Phosphate, our goal is to become a leading global supplier of direct application phosphate for the agricultural sector. We are deeply committed to promoting sustainable farming through the use of natural, slow-release phosphate fertilizers.
Our Direct Application Phosphate Rock (DAPR) is ideal for long-term soil nutrition, gradually releasing phosphate under acidic soil conditions. The phosphate release is further enhanced by the presence of soil moisture, ensuring consistent nutrient availability over time.
This environmentally friendly product is well-suited for maintenance applications and can be safely blended with elemental sulfur, dolomite, or magnesium oxide to meet specific soil requirements.
