Global rock phosphate deposits and their quality

Quality of organic manures vary widely, depending on the materials used. However, basic criteria to consider suitability of the material as a nutrient source are:

• Organic matter content by weight: minimum 30%
• Organic carbon content by weight: minimum 12%
• Total nutrients (N+ P2O5+ K2O) content by weight: minimum 5%

Subject to doubt and availability of analytical facilities, contents of following heavy metals should be checked:

• Arsenic (As) content by weight: maximum 10 mg/kg
• Cadmium (Cd) content by weight: maximum 5 mg/kg
• Cromium (Cr) content by weight: maximum 50 mg/kg
• Copper (Cu) content by weight: maximum 300 mg/kg
• Lead (Pb) content by weight: maximum 100 mg/kg
