Corn Meal and the Lawn

200 pounds of corn meal went down today, and I'm starting to account for the area that will end up being planted with Thuja come April. As of now, I'm using a typical standard of 6,000 square feet of lawn, figuring that about 1,000 will either be under or behind the new bushes and I won't want to feed it because I don't want it to grow that much.

So that works out to 33.3 pounds per thousand, about half what I'd like to add (but I could only get 4 bags and will need to go for four more). Corn meal is mostly a soil conditioner, or used to combat fungal issues, which I don't have. I'm looking to deepen the topsoil more, however, and for that it works well and can be put down in very large amounts as it has few resources. I use a standard NPK of 1.65-0.65-0.40 for that, a far cry from soybean's 7-1-2.
