Rock Phosphate are natural deposits of phosphate in combination with calcium. The material that is dug from the earth is very hard and yields its phosphorus very slowly. When finely ground and with impurities removed, the powdery material is only slightly soluble in water, but may be beneficial to plants in subsequent seasons following application.
The reaction of phosphate rock with acids from decaying organic matter in the garden or compost tend to make the phosphorus available to garden plants.
You can speed up the release of the phosphorus by combining the rock phosphate, with a beneficial fungi called Mycoroot. The fungi help to break down and release the phosphorus, thus making it available to the plants roots.
- Reduces immediate Nitrogen loss as it encourages nitrogen fixing and reduces manure odour.
- Increases phosphorous reserves where there is a deficiency of phosphorous.
Essential for rooting and later stages of flowering!
Rock Phosphate is commonly called “rock dust. The use of rock phosphate for gardens is a common practice for both flowers as well as vegetables. Flowers love an application of rock phosphate and will reward you with big, vibrant blooms.
If you use rock phosphate in your vegetable garden, you will have fewer pests, greater yields and richer flavour.
Warning: Do not use more than 2% of the total volume of your growing medium
