Jun 01, 2017· Tunisian rock phosphate belongs to the francolite (carbonate-fluorapatite) group. This structure tends to make rock phosphates more reactive when directly applied to soil. Consequently, the apatite of reactive rocks has a greater ability to dissolve in the soil and to release available P to the plants than unreactive rocks.
