Daniel Kern : I am well out of my comfort zone on any specific advice here But It would appear that "Cotton root rot'' is perfectly suited to is environment !
You really need to have a Mycologist to give you answers here ! I highly respect the knowledge of and the opinions of Paul Stamets, perhaps there is a more
dominate fungi, or one that careful feeding can make more dominate!
I am sure that you will resist the offers of using massive amount of fertilizers to sterilize Your soils, Just be aware that your neighbors may have bought into
this abusive pattern, and will ask you too to ''Drink the Cool-ade'', and your failure to march in lock step may cause them to actively shun you to the point of
not wanting to part their Farm vehicles near yours in town !
Hopefully, you will not find your situation quite so odious, Good Luck! Hope this is in some way useful to you and timely ! For the Good of the Craft! Big AL

Good points. I definatly won't be going the chemical route.
I believe that you are right and that by changing the environment that the fungus lives in then you could encourage beneficial fungus.
I just bought some reishi mushroom plugs from Paul Stamens. I know he also does have some mushrooms for mycoremediation. I'll have to do more research, but that may be the way to go.
