Eaton, Ohio
This has for some reason been lingering in my head.... When we buy nitrogen (28-0-0), where does it originally come from? I don't mean where you buy it from, but how is it made? Is it a natural resource mined from somewhere? Or is it somehow man made? Please enlighten me
Where does nitrogen come from?
