Mycos applied to the soil surface should at least partially colonize the soil as long as it is kept moist and the temps dont get out of control.... it is not nearly as effective as if it had been tilled into the soil before planting. When you use mycos... you are innoculating the ground with dorment mycelium of several types of fungi... when the mycelium becomes active, it will spread... colonizing whatever substrate it can get hold of... and feeding the byproducts of that metabolism to your plants in a bartering system.  Same prinicple applies to the beneficial bacteria, nemetodes, and protists one might innoculate the soil with.Â

By the way... I just discovered jobe's. I applied the first dose a few days ago. I am assuming you also got the "biozome" formula with all of the microorganisms. I went ahead and applied it to the soil surface in a thin ring around each plant... and then covered it with a thin layer of mulch. If you have any mulch or compost, it might be a good idea to put a thin layer on top of the jobe's... this will help to get the myc going.. and will prevent all of your varius non-soluable 'meals' from blowing away.

Oh... and about using mycos in compost or worm tea... it can be done... but you are supposed to include something that floats on top of the tea while it is brewing. This will literally provide a raft for the myc to live on....
