Who is using Myco? Where are you purchasing from? What form do you apply in? Soil drench/granular/gel dips/spikes/vertical mulching/radial mulching etc etc

If you don't want to reveal your source here please PM me.

Thanks!
 
SRQFLTreeLady, I'm confused by your pictures. How does showing a picture of a tree with increased flowering reveal the success of your injectable?

Even oak root fungus is a beneficial mychorrizal in the right conditions.

Went to a conf. where Nelda Matheny spoke about competition between microbes, local fungus strains can attack store bought myco. strains...no guarantees on those.

Mycos. can increase P uptake without having to add P to existing soil...more flowers, defence no "salts"

Also helps against drought stress.

I use a starter batch of local myco (leaves, soil), couple shovels full, to a similar Sp. chips and compost on site.
 
Last year I read "Trees and Toadstools" by M.C.Rayner, as a bit of an introduction to fungi. It described a similar experiment, planting trees in soils inoculated with soil, leaf humus and root matter from forest floors, to start up the mycorrhizal relationship. The book was published 1945, so the study would have been even earlier, pretty neat book.

Maybe inoculation speeds the process, but it seems a healthy soil won't be lacking the right spores at the right time.

We dropped fungal inoculants from our planting specs as it had been impossible to enforce. I busted an earlier contractor with bags of bacterial inoculant made for soybeans, "What do you mean this isn't the right stuff?"

Hello,new here and expect attrosheeous spelling.

I have a question about mycorr if I may?

a plant may have phytophthora so we treat with Subdue systemic fungicide, which is actualy a fungistat. This inhibits the growth of all natural soil fungi until the residual wears off. I heard when mycorr is killed the portion of root it was attached to dies as well.
would it be acurate to say that if Subdue were a fungi"cide", applied as a drench it would kill the tree knowing how prevelant mycorr is in soil?

First let me state that I am not a plant pathologist, by any means. I read quite a bit and sometimes even remember what I read. Your thoughts are on the right track but you need to be wary of absolute comments. For example: "Topping kills trees"

A fungicide can indeed cause the death of a tree, but will it ALWAYS? When the mycchorizae die a very small portion of the root structure is damaged and that is in direct relation to the type of mycchorizae and its method of attachment.

The link I am posting has some good generalized information on mycchorizae. But their information may be somewhat biased in the use of their particular "silver bullet". The descriptions of the life within the soil, in my mind, is what it is all about. We would like to have the answer be "one thing" but I'm afraid that is not going to be.

By the way, welcome to this site. Talk more on Friday.

Yeah, ok. U busted me.

So much for easing into TreeBuzz anonomously.

Lets get 2 it.

1. The hyphae of mycorrhizal fungi penetrate roots and grow extensively between and within living cortical cells. Im interested in learning from data that concerns the event of dying mycorr and the fibrous root material its attached to.

2. "We have also learned that the often higher stomatal conductance of mycorrhizal leaves is tied to slightly higher water potential gradients across leaves, consistent with the higher rates of gas exchange necessary to supply the carbon needs of the fungal symbiont"
(Augé et al. 2008).

is mycorr inoc being though about for bls as a potential opportunity to dilute the pathogen within the plant?

Lots of good thought on this site. This should be fun.
 
hmmm. A subterannean use for SRT, right down into the grounds. 'A' horizon, humus, bedrock. difficulty pushing the ascender though hard packed dirt. Compaction has no shortage of ill side effects. Probably seek a Certified Tree worker to consult. Probably, a headlamp is a must.

The plant's intake of Co2 is increased, is that right?

never heard that...

Very cool.
 
KnowledgeQuest,
I can remember a time when one of your lab experiments was the hydroponic tomato growing thingy or something like that. And I totally think you should capitalize the 'Q' in your name.

Sincerely,

Morice

The experiment you remember was my effort to graft a tomato plant onto a potato plant... May have worked if the lab assistant would have watered the thing, huh?
kidding, it was doomed 4rom the start.

While you worked for the big "B" were u ever instructed to throw a bag of mycorr into the tank containing the slurry of macros/water in an effort to "increase vigor and root density"? i can not count the times.

Kinda like puttin hubcaps on a tractor.

i am of the belief that the relationship between the microrganisms and the tree is more important than supersaturating the soil with elements which disturb that relationship. Ask E.L. or Dr. K about this on your next visit.

Well we know that the equation below represents how a plant emits O2 and metabolizes.

6CO2 + 6H2O (+ light energy) --> C6H12O6 + 6O2

6 Carbon dioxide molecules plus 6 water molecules plus energy (6 H2O) are remade into 1 glucose sugar molecule and 6 gaseous oxygen molecules.
Perhaps it can be said mycorr very simply helps a plant realize its metabolic potential?
 
So what was the question?
Plant performance, what it actually does, is an interaction between the genetics of the plant and it's environment, over time. Sure, in supplying essential elements and environmental protection to the host plant, mycorrhizae do help the plant realize it's metabolic potential. Similarly, the plant helps the fungus achieve *its* metabolic potential. It's the webwork that keeps everything humming along!
