- 10. The method of claim 7 wherein the act of heating said mixture of components is performed in said pellet mill.
- 11. The method of claim 8 wherein the act of heating said mixture of components is performed in said pellet mill.
- 12. The fertilizer pellets prepared according to claim 1.
- 13. The fertilizer pellets prepared according to claim 3.
- 14. The fertilizer pellets prepared according to claim 5.
- 15. The fertilizer pellets prepared according to claim 6.
