Great source of Calcium and Phosphorus.

Whether it’s the price, or the overall quality of the product, this is the best replacement for rock phosphate there is.

Very pleased with this product. I've got containers where I used it as a top dress and others where it was mixed into the soil beforehand. Happy with both.
