That’s exactly how I use mycorrhizal inoculants; I add them after solarizing the soil, to try to establish a presence of beneficial organisms in the sterilized soil before pathogens can find their way back.

Alan Haight recently cited a reference by Wiseman and others that showed some benefit of mycorrhizal inoculation. Two important point emerge if you read the actual publication:

 

1. The experiments were conducted in sterilized soil so the results would not necessarily apply to field soils. Mycorrhizal inoculae generally exist in sufficient amounts in such soils.

 

2. The benefits seen from inoculation was not related to the actual amount of infection seen in roots. Something else may be going on.

 

Mycorrhizal associations are, no doubt, beneficial to plants. Deliberate inoculation, especially with commercially available inoculae, are not necessarily so.
