Soft Rock Phosphate
- By DJ on Jan 23, 2014
Tried soft rock phosphate for the first time and now I don't know why I waited so long! It's great and inexpensive.

Rock Phosphate that is not treated with hydrochloric acid like super phosphate, is a long lasting addition to the soil. It is slow leaching and will improve the soil for 3 to 5 years. It has a number of trace elements that are super valuable to your health and that of your plants. Along with Granite Dust and compost/manures you'll improve your soil so much that your healthy plants will resist insects and disease and produce the best produce for your good health. Worth the effort.
