    just wondering if you can mix liquid nitrogen with a standard 2-4D for an all in one liquid weed'n'feed ??


    i could put down the par 3 or killex or whatever, and fertilize later but would be handy for next spring...

    Sure you can. 2,4-D and UAN is one of the standard tank mixes for a corn farmer. On a lawn, you would do well to apply such a mix containing 1/2 lb N from the UAN and the required amount of 2,4-D in 3-5 gallons of water per 1000.

    I use a product called CORON, basically CRN--24/0/0 liquid from Helena Chem.
    But mine is a substitute N feeding and not to be considered a full regimine feeding.
    You still need to apply a normal gran fert to sustain the feeding.

    true, well not legally i guess.

    but believe me, the "2,4-D police" arent swooping down from helicopters on anyone using it....yet.

    I am guessing your not licensed Steck.

    Ive lost 70% of my spray customers ($30,000).
    Its a bummer for me always following the rules. You should see the dents in the wall, I mean my forehead.

    Mixing the two shouldn't be a problem, cation should be used even test strips, before applying uan (28-32%N) can be a hot mix and burn vary easlily.
    I think it will work just don't mix it to thick, water maybe need to dilute.
    Just something to think about and take note.

    In warm weather you will burn the bajabbers out of the grass--if that doesn't matter...sure.
