what seems to be interesting to me, is that bacteria have very little overhead to the trade in relationship between them and plant, where as typically when we discuss fungus and say P acquisition in low P media, there is usually some payment to be made, this may well be in alternate protein cascades via required additional gene insertion, and this might actually result in a lower yield than if we amended with liquid P inputs, perhaps not as low as it might otherwise have been the case without the fungus (or help), but perhaps the harvest has less flavor or some other cute human property, or it ripens faster, slower...
What i can say with certainty, I have a cannabis plant that I have been growing now all year,. I have cropped it already and its now going for another run. i didnt do anything special, i just neglected to remove the whole plant, this due to other commitments as priority.
On remembering i hadnt cleaned it up, I happened to make time to check it, this was about 3 weeks later and I noticed it had lots of new growth so i just left it. I read about hemp and its ability to regenerate despite a really heavy cropping, taking the plant back to a stump, similar to roses, or even many vines such as grape, so i left it going, well it, i have 2.
This plants are associated with 2 strains of glomus, having taken root samples and tested them to confirm. this may well be a result of changing environmental's over the course of time. its been quite cool here, and then blisteringly hot. Rhizophagus irregularis and Funneliformis mosseae in case you were wondering :) It just may be the ash i use in my soil mix has sounded the alarm and rallied the glomus?
I have periodically been adding several strains of PSB and KSB etc, alongside some bio control ento fungus, yeasts, trichoderma and bacteria, but of course I am not adding more Mycos.
I have seen drops in mineralization across the time, I suspect this is standard bacterial warfare and the odd low oxygen moment and related protozoa swarms. Quick top dress with BMP and Wormcast ...or batguano ...I aint Elaine now am I, and i quickly pick up the flaws without stress.
I have been using similar products to you, those i make of course, you really would be amazed at the difference in the land here already, only 6 months of BOX love. I have worms. I am the only person for miles around to have visible worms, mm from the surface in a country not known for its worm populations. I havent added these, they came as the soil tilth returned and we got a handle on the toxins through the insertion of fungal mulch.
Biggest headaches i have are from the past tenants of the land I am transforming here.
Existing practices here are a little behind the curve and so there is abundant sclerotinia and massive soil profile collapse.
I have been pre staging my planting here with Citric acid and Zinc AA chelate to help mitigate the hazard, but the near 30 years use of pesticide, herbicide and fungicide is making my life harder than it ought to be :)
I am manually removing plants across the farm estate, this way I understand why and how before i take away anything useful. I have found some really interesting stuff growing among the wild plants here, including ones that are anti lipid accumulation, anti psychotic, and some that release critical VOC's essential for ground beetle communications. In light of the importance of these ground beetles to the health of my system. I am leaving most of them in the ground and removing only the ones that are problematic for the tree growth.
I am replanting bio control plants and a border of predator bug host crops this winter. I will be laying the new wood chip paths at this stage also. next year i anticipate a lot less work :)
This is why i grow organic, its less work even if i do get the odd drop in yield, crop dependent.
by the way, Tim is a good dude, Elaine was a pioneer along with Jeff and her husband. Tim imo has very practically added to Elaine's work, as have now popular faces like Ray Archuleta, David Moore, Paul Stamets, Urs Niggli, Mike Harrington. Not to mention the thousands of unseen students around the world adding to the academic understanding which we as growers must decide the value of.
The new problem is how to measure for biology simply? The easiest way to know how well our microbes are working, is to monitor the CO2. Easy to use burst rate tests are available from other thought leaders such as Dr Rick Haney over at Solvita. I think we are right at the begining of this bio journey and so i tread carefully to say what microbes will and wont do. I am not sure we really understand fully the mechanisms.
