The bag rate is not enough N. The Milorganite bag rate may is likely legally limited by the high phosphorus content. (All manure based fertilizers have high phosphorus.)
The bag rate is perhaps adequate for people with typical mixed KBG lawns who do not irrigate and who do not visit lawn forums.
I do about 3X milo bag rate twice a year, In addition I do a grain based organic fertilizer at about 3X the bag rate twice a year. Grain based fertilizer are essentially high protein animal feed and contain no phosphorus. Some soil chemistries have problems with too high phosphorus. So I'm offsetting the high phosphorus milo with a the second fertilizer.
I do a Thanksgiving fertilizer treatment and then no more until mid may. I have green grass in early spring but have avoided forcing growth with fast acting nitrogen. I have by far the greenest lawn in winter in my neighborhood. In my experience an all organic lawn gets thicker, not taller, in cool weather. Mowing in summer is about the same as with inorganic. I am sure that forcing greening and growth with soluble nitrogen causes many lawn problems.
I think that milo plus inorganic is fine if you are not accumulating thatch and have no disease. Thatch and disease are primarily caused by mismanagement of microorganisms.
