How to Apply Rock Phosphate Fertilizer Rock dusts are best applied in early spring. Aim for 10 pounds (4.5 kg.) per 100 square feet (30.5 m.), but be sure to read about application rates on the package label as they may vary. Adding rock dust to compost will add available nutrients for plants.
10%Purpose Phosphorus (P) deficiency in agricultural land is one of the main factors which reduce the crop production and yield. To increase the crop growth, the availability of P using the rock phosphate (RP) can be enhanced using organic waste with the addition of phosphate solubilizing microorganisms (PSMs). Moreover, the combination along …
Chapter 4. Evaluation of phosphate rocks for direct application. Chapter 3 described the characterization of phosphate rock (PR) materials for direct application. Depending on their origin and geological history, PRs show great variability in their inherent properties, especially in their grade, beneficiation requirements and apatite reactivity.
Figure 1: The process used to manufacture various phosphate fertilizers. Dry vs. wet process. In the dry process, an electric furnace treats rock phosphate. This treatment produces a very pure and more expensive phosphoric acid – frequently called white or furnace acid – primarily used in the food and chemical industry.
