PHOSPHORUS FERTILIZER TABLE –
A legislative analyst from Connecticut put this information together. It has a nice table comparing the 11 state P restrictions (FL is excluded) and links to each state’s statute. 

[Please note: the word “ban” is used here, it should really be “restriction” as the state laws do allow for certain uses of phosphorus fertilizers.]
