Of course I did. There has not been any visible change in the soil structure below the crown level of the grass. The grass has deeper roots, as expected this time of year. I used the compost to bed #350 of seed (overseeded field). I used straight compost mostly to avoid starting a soil layering problem that might haunt me later (because it does not migrate but stays on top where placed) but also because I knew it would help my seed get a good start under difficult circumstances. It looks good by the way.
It is a heavy soil filed. I hope to deep core aerate next year instead of topdress but am not sure yet.
