    You may be correct! However, the stuff used by farmers in the
    Midwestern US  is "called" anhydrous ammonia & is a liquid.
    Depending on  location, it's shipped in aprox 10,000 gallon tank
    trucks from the mfg plant directly to the end user. The safety
    restrictions around it's mfg, transportation & use are strict. 

    Like everything else that's sold in this world, the name may be a
    figment of some advertising execs imagination, with just a little
    bit of truth. 

Dave
