Phosphate Rock

Description
An excellent natural source of phosphorus, calcium and many essential trace elements. It contains over 30% total phosphate (3-8% available) and 48% calcium (as CaO).

How it works
Builds phosphate fertility where levels are low. Increases rooting activity in transplants and sprouting seeds. Also mineralizes the soil and improves quality of crops and soil structure. Its slow release allows plants to use it before it is fixed.

General usage
Use to help plants adjust to transplant stress. Phosphate rock cannot burn roots.

Directions for use
Apply 1-2 lbs per plant for tree or shrub transplants. To correct soil deficiencies, apply from 500-4,000 lbs per acre depending on severity of deficiciency.
