This fertilizer is a combination of black rock phosphate (phosphorus), marl (calcium), and carbonitite (broad spectrum minerals). These nutrients are released slowly, providing long term fertility when combined with composting and rotation planting. Directions: Apply once per year. Mix into garden beds 15 ml (1Tbs.) per square 30 cm (1 square foot) or sprinkle lightly over the lawn in early spring. CANADAIN ORDERS ONLY
