    I was wondering if anyone here has had luck with using corn gluten for the first time. Any real weed control? I know it will get better as the CG gets prevelant in the soil. Just so they don't move this thread, This is a Fertilizer to 9-0-0.

    Shades: I went to the local fertilizer place and tried to get the corn-gluten, but the guy looked at me as if I had come from Mars. Where did you ever find it, especially up there. I thought for sure that it would be available at a Co-op. Ha Ha. What grass were you trying it on? Fescue? I'd like to try it on centipede.

    The jonathan Green dealer has it, and there is a place called blossoms that sells it. I was gonna try it on a fescue yard.

    I was involved with some controlled trials of CGM more years back than I care to remember.
    Several things I discovered.
    The overall determining factor of any success, well any success I noticed, hinged upon the manner the GCM was made - it has to come from a wet milling process with a very high degree of control on the final, bagged product.
    Soil types was also an Achilles heel to the efficacy of the GCM. Heavy clay based soils with limited exchange sites meant the GCM wouldn't work.
    Application rates where over 30lbs/thousand feet with repeated applications that absolutely had to be timed properly or all you accomplished was becoming a yellow, gasping, smurf.
    I know that Iowa State, Purdue and Penn State have all at one time or another examined GCM so check their sites for more info.

    hmmm. i see this as an opportunity. i think i might do some tests of my own on a strip of my personal vegetable garden this season. it works for me in my customers annual beds i know for sure, just from comparing from one year to the next.

    If you guys are looking at a Corn Gluten product for this season let me know. I may be able to get some pricing.
    Up here in Maine many LCO's (including us) are using it as part of thier program. Clients will have to realize that it is a process of getting the CGM to work over a few years, but there are programs we have developed to not only help spread the costs out over the season on all nautral programs.

    A friend mentioned to me that as the CGM builds up over repeated applications that you will have problems getting grass seed to germinate in the fall. Any truth to that?

    Somewhat true, however it also depends upon the milling process the CGM has been derived from. CGM naturally acts as a preemergent herbicide so toxicity in the soil can be a concern.
    However, normal cultural practices to the site, aerification/power rakings will typically break that seal the CGM residue provides so re-seeding an area will work.
