RE: [compost_tea] adding VAM ?



See correction, should have read palms, that was the first population we targeted.

The only point I was trying to make was the availability of opinions and products outside of the posters in this group.

 

I was trying to resource another group member. We found that a number of AM products on the market were long winded on sales and short on spore count.

 

Since I am not a scientist, I have followed Dr. Mike’s lead and taken PALMS from devoid of Endomycorrhizal colonization to a high percentage of colonization. It’s been obvious through this process that some species colonize while others have not. I was trying to suggest Laura ask the question on grapes.

Hi Laura,

 

I got a good chuckle out reading how far off base Tom J., was in his opinion about AM fungi with grapes.  I know Mike Amaranthas and he's a personable guy, but his research has been mainly dealing with ectomycorrhizal fungi which have little to do with benefiting grape plants.  Mike does make a rather strange endomycorrhizal fungi inoculum in tablet form.  A local mycologist at Eastern Washington University who's specialty is working with AM fungi tested those tablets and found little to do with endomycorrhizal fungi and a lot to do with fertilizer.  Dr. Ted Saint John would have fun ranting and raving about that one.  :) 

 

It looked like Tom J was trying to say there was a specific species of mycorrhizal fungi that works with grape plants.  To be blunt, that's ridiculous.  Any of the 56 odd glomus species of endomycorrhizal fungi will colonize grape plants.  When you get into endomycorrhizal fungi and try to say that only a specific species will benefit grape plants or another specific species will benefit a tomato plant, etc., that claim is outside the realm of known research on the topic of endomycorrhizal fungi.  It's fairly safe to say that endomycorrhizal fungi species are not plant species specific.  In fact research states that under the right biological conditions AM fungi will grow into the roots of all terrestrial plants.  To turn that around a bit, it is also safe to say that grape plants are NOT benefited only by a single species of endomycorrhizal fungi.  That's a claim out of the past that simply doesn't stand up to research findings or reality out in the soils.
