concern corn gluten

concern corn gluten

has anyone had any luck using corn gluten for weed control, specifically Concern brand (it is 82% corn gluten with bone meal, wheat middlings and something else as fertiliser). im using it to control the grass burrs (sticker grass) around my property. fyi: corn gluten, and im not sure how, is supposed to supress the ability for seeds to start while leaving established plants alone. edit: the soil in the front yard tends to get really compacted over the year, despite being pretty sandy. other that peat moss, (i dont want the soil getting too acidic) what can i add to give the soil volume?
