What's your soil like? Does it leech N/P/K? Is it compacted? Thatch accumulation? Is it a Loam/Sandy soil?
Based on my March soil test, my soil needs some help. CEC averages to about 4.6. I core aerated last fall to relieve compaction, but I'm sure it needs it again this year. I dethatched last fall as well, and lightly raked to stimulate growth this spring. Based on my location (southern New England) and CEC numbers, I would say it's a sandy soil.... and quite a bit of it is steeply sloped.
I put down four bag rate applications of Milorganite last season, and still came up phosphorus deficient in my soil test! In fairness, last year was the first year I've ever really paid attention to my lawn.
As another poster mentioned, once you get to the over 15K sq ft mark (particularly with steeper slopes), cost, time, and effort become serious issues. I'm trying to develop a strategy that makes sense. The vibe I'm getting is that I should just focus on proper pH, fertilizing, dethatching, aerating, and mowing. My thought was to try to improve my low CEC, but throwing big $$$ at products that will have a negligible effect on a yard so large makes little sense I guess.
