If you're using it in a garden, I'd recommend the manure IF you can make 100% certain that the animals that produced the manure didn't graze on grass or eat hay that was sprayed with Grazon

You won't have a garden for a year or two if they did. Been there, done that.

If my people, who are called by my name, will humble themselves and pray and seek my face and turn from their wicked ways, then will I hear from heaven and will forgive their sin and will heal their land. 2 Chronicles 7:14
