You must've read Teaming
My man!!!
Though you have pointed out probably the biggest reason on the benefits, molasses does provide more than a carbohydrate energy source to the soil food web.
Averaging an NPK of 1-0-5, molasses contains potash, sulfur, and quite a feww trace minerals; it can serve as both an excellent chelating agent and a soil conditioner.
It is interesting, however, that oatmeal isn't used more. Powdered baby oatmeal is actually a more stable carbohydrate source for fungal mychorrizae. Molasses has a wider spectrum for both bacterial and fungal applications, however.
Funny how some people are like: "molasses made my buds taste soo sweet". LoL.
Glad to see some truth here...+rep
