Soft rock phosphate, or colloidal phosphate, is a natural, untreated source of long-lasting phosphate and soil-building calcium. Phosphate will remain available across a wide pH range. For best availability, soft rock phosphate should be mixed into soil or compost prior to planting. A superb nutrient resource for all types of plants.
