Regarding corn gluten: Just in case you don't know or forgot why we use corn gluten...it has pre-emergent capabilities meaning that it prohibits seed from germinating. We look for this to reduce the amount of dandelion seed from germinating in the lawn.
Some people also use corn gluten in their vegetable garden to inhibit weeds sprouting from seed. Obviously you would not put this down where you want seed to germinate such as grass seed or a row of beans.
Corn gluten also acts as a fertilizer with a good rating of nitrogen (I don't know the N rating on it). That is good for grass in the spring and other plants that like some nitrogen for foliage growth.
