T/his is a mined rock phosphate from Florida.  It contains around 3% available phosphate (but 20% total phosphate that your microbes can work on unlocking for your plants).  Also contains 20% calcium as calcium oxide.  

Use where phosphate is needed at the rate of 250-1000 lbs per acre, or more in soils very deficient in phosphate.

Always check with your organic certifier before using any product.
