We are offering blended yellow corn powder chicken feed, corn gluten meal (often simply called cgm) is a byproduct of corn (maize) processing that has historically been used as an animal feed (take note that the expression gluten here is inexact; there is no true gluten in corn, but simply corn proteins. The expression "corn gluten" is colloquial jargon that describes corn proteins that are neither gliadin nor glutenin. Only wheat, barley, rye and oat contain true gluten which is formed by the interaction of gliadin and glutenin proteins). It can also be used as an organic herbicide. corn gluten meal is applied using a spreader or even by hand: the material is essentially harmless if not inhaled, and is, in fact, edible (though not particularly palatable). On lawns, cgm is applied in early spring (usually timed phenologically by the blooming of crocus or forsythia), and again in the autumn. If the lawn is overseeded, cgm should either be applied at least six weeks before sowing, or two weeks afterwards.
