I quite agree with you. Most lawns that are left alone and the clippings are recycled into the turf, seem to do just fine. The microbes are cycling the nutrients as they should and the grass grows up another year.
The problem is - it is not green enough, so we throw on some N. It greens up and everyone is happy.
The question is: Does a healthy lawn need all that N or all that protien?
Is there protien in the grass clippings? leaf mulch? Thatch?
Does a lawn with too much N become suseptible to various fungal diseases?
Does excessive N cause abnormal growth patterns known as thatch?
I don't see Milorganite as a soil builder, just as a good way to apply some N and Fe that is relatively stable and slow release, in pace with the microbes that degrade it.
