4 . The fertilizer granule of claim 1 , wherein the coat comprises 0.5 wt. % to 30 wt. % of the wax.

5 . The fertilizer granule of claim 1 , wherein the PBSA and the second polymer is comprised in one or more polymer coating layers and the wax is comprised in a wax coating layer, wherein the one or more polymer coating layers are at least partially located between the core and the wax coating layer.

6 . The fertilizer granule of claim 1 , wherein the PBSA and/or the second polymer is comprised in a first polymer coating layer and at least a second polymer coating layer, wherein the first polymer coating layer and the second polymer coating layer are different.

7 . The fertilizer granule of claim 1 , wherein the coat comprises a wax and the wax is an alpha-olefin wax, paraffin wax, or natural wax, or combination thereof.

8 . The fertilizer granule of claim 1 , wherein the PLA has a weight average molecular weight (Mw) of 100 kg/mol to 200 kg/mol, the PBS has a weight average molecular weight (Mw) of 20 kg/mol to 500 kg/mol, and/or the PBSA has a weight average molecular weight (Mw) of 20 kg/mol to 500 kg/mol, as measured by GPC.

9 . The fertilizer granule of claim 1 , wherein the coat comprises 10 wt. % to 30 wt. % of the PLA and/or PBS, 70 wt. % to 90 wt. % of the PBSA, and 0 wt. % to 10 wt. % of the wax.

10 . The fertilizer granule of claim 1 , wherein the coat has a thickness of 10 μm to 100 μm over the core.

11 . The fertilizer granule of claim 1 , wherein the plant nutrient comprises nitrogen (N), phosphorus (P), or potassium (K) or any combination thereof.

12 . The fertilizer granule of claim 1 , wherein the plant nutrient comprises urea.

13 . The fertilizer granule of claim 1 , wherein the fertilizer granule comprise 85 wt. % to 98 wt. % of the core and 2 wt. % to 15 wt. % of the coat.

14 . A coating composition comprising 55 wt. % to 90 wt. % of a poly butylene succinate adipate (PBSA), 10 wt. % to 45 wt. % of a second polymer selected from poly lactic acid (PLA) and/or poly butylene succinate (PBS), and 0 wt. % to 30 wt. % of a wax.

15 . The coating composition of claim 14 , comprising 65 wt. % to 90 wt. % of PBSA, 10 wt. % to 35 wt. % of PLA and/or PBS.

16 . The coating composition of claim 14 , comprising 0.5 wt. % to 30 wt. % of the wax.

17 . The coating composition of claim 14 , wherein the coating composition comprises one or more polymer coating layers and a wax coating layer, wherein each of the one or more polymer coating layers independently comprises PBSA, the second polymer, and/or a blend thereof, and the wax coating layer comprises wax.

18 . The coating composition of claim 14 , wherein the wax is alpha-olefin wax, paraffin wax, or natural wax or combination thereof.

19 . The coating composition of claim 14 , comprising 10 wt. % to 30 wt. % of the PLA and/or PBS, 70 wt. % to 90 wt. % of the PBSA, and 0 wt. % to 10 wt. % of the wax.

20 . A coated material comprising a material at least partially coated by the coating composition of claim 14 .
