Re: aerobic compost tea
Another reason why capitalism blows sometimes. It is very difficult for an arborist to brew compost tea and manage his three crews. I think about that a lot, it would be nice to have a full scale vermicomposting project going on as well. It would be nice to have a crew working just on worms and compost tea and fungus prduction.
As for mycorhizae, I think most urban and suburban lawns are dead and sterilized to begin with. They theoretically would benefit by adding innoculant. Actually, in Detroit, the city's soil is healthier than suburban lawns sometimes because of the amount of pesticides, herbicides, and fertilizers dumped in the burbs with all organic material hauled away. Dead yards can still be green, The color is maintained by chemical inputs like life support.
In those applications however, it is just silly to add living matter to the soil if the owner is just going to kill it after you leave with ortho or call in true green/chem lawn. A whole mental shift must occur with the customer before using these techniques sometimes.
