Hello, I have a question about corn meal. There seems to be alot of discussion about Corn Gluten Meal, but what about just plain Corn Meal? I'm thinking about applying some to me lawn to stop some brown patch from spreading. I overseeded last month and I know fescue seed can germinate throughout the Fall in the South. (Warmer temps longer) Does Corn Meal act as a pre-em the way corn gluten meal does? What is the NPK of corn meal. PrimalSeeds.org says: 1.65 - .65 - .4 Does this seem right? Another questions is what about ants? I read somewhere using this stuff is like ringing the dinner bell for ants.....especially fire ants. Suggestions?
