I have also noticed additional bio growth within the vegetative state with additional enhancements such as co2 red light frequency adds a higher yield. In my research I discovered an accelerated growth of the Calvin benson cycle

[@bhuwaneshwarithakur9269]

Thank you so much for this information🙌 I have a presentation on this topic and this is exactly what I was searching for ! Great presentation 👏

[@katrina6627]

I use when watering & transplanting my seedlings . The results are excellent.

[@louco86]

Great information thank you! It’s sad that fertilizer companies restrict healthy practice information in order to keep people relying on fertilizer. This was a fine finesse of explaining, great job 👏

[@shudiprai9384]

Very nice presentation

[@jeffrogers210]

The "promo card" image shown on KZbin looks like a Guided by Voices album cover. Cool!

[@alimohammed2467]

Thanks for the nice presentation. In 32 min you present a table can you please mention the reference of this table. Thank you

How to innoculate the fungai in annuals?Does seed treatment with mycorrhiza work?

[@williamgibson2760]

Yes it does.

[@vidaripollen]

Very interesting, thanks 🎉

[@hlainghlainghtaymycorrhiza7260]

Thanks

[@armandobambino]

hi, great preentation, thanks. One question: can I mixing with the seed directly?

[@LostlnTheWoods]

No

[@thetruthserum2816]

What is all that racket noise in the audio? Sounds like someone banging on pipes the whole time... having to skip it.

[@rpw53]

Looking for mycorrhizal fungi for use in commercial field production of Lavandula, any recommendations on species or products? Thanks.

[@williamgibson2760]

I don’t know if Lavandula is AMF-associate, but if it is I have been very pleased w field applications of annual and perennial ag crops with both Lallemand Plant Care “LALRISE” & MycoApply choices.

[@libraryofpangea7018]

You don't really need a product if you know how to create a culture- AM fungi can be harvested from most soils since they are ubiquitous symbiotes for most plants. Start with a process called wet seiving with your field soil, to see what AMF are already there. Then in a green house run pot cultures. Once you ID the species that are doing best with your pot cultures, you can isolate them and extend those to seed mats. The infectivity of the soil can be increased by using roots as propagules, so the goal is to create as much root surface area as possible. You can then add these as an amendment to increase the infectivity of your soil over time. If you do so, be mindful of your water soluable phosphorus levels in the soil as this will reduce symbiotic activity. The trick is it is better to apply phosphorus sources that are long lasting in the soil but less bioavailable directly to the plant- rather attach it to a source, such as organic matter, that can be scavanaged by the extraradical mycelium. So that you are not sacrificing phosphorus uptake but instead are attaching it to the AMF relationship.

[@primelricafrente]

Thanks for the info... Is it possible to combine it with fertilizer? Because we have an organic liquid product here with NPK in NZ... This is a game changer for all vegetables and fruits

[@nkyabosi4827]

Primel Ricafrente have you heard of blackoff and bio bloom Organic fertilizers ? I recommend them to any organic farmer

[@stevenwicks6451]

Plants will restrict or stop the sybiosis if they are fertilised. If they get all their needs from fertiliser application they will not allow fungi to colonise their roots.

[@williamgibson2760]

@@stevenwicks6451 it does depend on forms/sources of nutrients & which ones: particularly soluble P at 30+ lb/acre at field planting seed is detrimental

[@cyberroth1]

So the take away towards the end is that "small companies" are not to be trusted while big companies like 'Mycorrhizal Applications' are good ? "Mycorrhizal Applications" appears to be a subsidiary of Sumitomo Chemical.

[@williamgibson2760]

I am blessed to do consulting & field trials for a small 3 yo start-up developing HQ well-researched microbials for ag obtaining NSF grants & getting state university research. Check out any company for these levels of research, public grants, independent & 3rd party results etc. Ask how they culture &/or procure their microbials & what research basis do they work from.

[@libraryofpangea7018]

No, the take away is look at the quality control and best practices of the company you are purchasing from. He is saying there is a lack of quality control by smaller companies because often they don't have the start up funds to conduct proper testing first. It isn't that none of them do it's just that the process itself is expensive especially in terms of the time it takes. So many companies instead portray primary literature as supportive of their product when often it actually isn't.
