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 15ml (1 tbs) per square 30 cm (1 square foot) or sprinkle lightly over the lawn in early spring.
Available sizes: 500 g and 1 kg
