Videos of Mycorrhizae Fungi - and - Questions and Answers




This one is Gabe Brown, a farmer in ND that had to change the way he was farming because the "traditional" way just wasn't working anymore. You can google him. He has a website. The changes that he's made to this place over the 
last 20 years is incredible.  He is one of the leaders of the regenerative agriculture movement and just really impressive.  Video is over two hours.  https://www.youtube.com/watch?v=uUmIdq0D6-A

Summary of videos (above)

- No till or minimum till

-Extracts N, Carbon, P, K from the air, puts in soil for plant, via the root system of the fungi.  Increases organic matter greatly.

- Rick Haney Soil Test ARS in Temple, Texas, now with Regen Ag Lab

- Takes 3 years to heal soil, bring back life to it.

- Use multi-crop for cover, fungi reacts different to different types of plants.

- Microbes, top 2" of soil (mostly)

- Book - Farming cover crops profitability, by Feir

- Radishs store N.

- Plantain (a plant for cover) - natural parasite killer.

- Carbonic Acid, created by this fungi, breaks down existing rocks and minerals in the soil for plant use, makes them water soluable.

- Mycorr fungi forms a biotic glue soil particles called gormaon (gor may on) - glomalin - this one probably right.

- Healthy soil should look like dark cottage cheese.

- Wheat, 1.2 million/acre seeds should cover 75%.

- More carbon in soil, more water holding capacity.

- Sare - Cover crop profitability, a book.

 
Questions and answers
 
Kent - I farm cotton SW of Lubbock, and want to put down mycorrhizae fungi on the crops, with boom sprayer, back of tractor, or through the pivot. I would like to experiment on 30 acres, that and N fixing bacteria I have used for 10 years, through Texas Earth. Could you educate me on how much to mix in 10 gpa of total water, beginning of growing season, and the cost, from you, to do so? Any other thoughts for me, just learning about this.

Zack -  we have a couple options for you. It will always be more cost effective to treat the seed: A 10 lb bag should get you close to that number, if you apply it to the seed ( $422 will treat 25 acres). About $16/ acre …..... Apply with seed & 2.5 # per acre for row crops.

Much like the mycorrhizal process, once it colonizes with the plant roots it will begin to colonize roots naturally without applications. It takes sometime, a few years of applying it with seed is the only way to get it to really stick.

 

Insecticide

Insecticide applied to wheat seed - does it harm the mycorrhizae?  Answer:  No.

..................

Innoculating Seed

Kent - Not sure how to apply to seed.  Please explain.  Can you boom spray it (the fungi) on?  I spray the bacteria on the plants, 10 gallon per acre of liquid, hits the leaves, the bacteria find their way to the soil, and I spray early morning, bacteria does not like sunlight.  Is the fungi sensitive to sunlight?  If not applied to seed, the rate of application to my boom sprayer, @ 10 gallons per acre of water?

Zack - You cant use mycorrhizae as a foliar spray. mycorrhizae are not effective negatively by sunlight. Mix 2.5 lbs of powder with liquid (250 gallons at least) per acre and treat furrow with seed, or you can add it directly to the seed (obviously you wont be adding 200 gallons to an acre of seed), as long as you use 2.5 lbs per acre you are good so you can mix with 25 gallons or whatever is needed.  Applying in the spring to seed works best.

 

We should maybe switch you over to something that will stick to the seed better, here are some options that i'm thinking.  This product is almost like flour, it sticks really well to hairy wheat seeds. If you want put it in a gandy box we have a product for you as well, u can just put it down next to the seed. Either one works.

My idea would be the to use either the granular or the ultra fine. Your typical cost would be anywhere from 7.50 (ultrafine) to 11(endo granular) dollars per acres.  Blend with seed in seed box of planter prior to planting Endo (granular) 1.5 lbs / acre.   Dust seed prior to planting Ultrafine (powder) .7 lbs / 100 lbs of seed.

                                                                                                                                                                                            Herbicide, Fungicide, and Synthetic Fertilizer

Kent - Pre-emergent herbicide?  Zack - Slow release does not affect the mycorrhizae.  Roundup – There are some ingredients in glyphosate that is hard on fungi.  There is an alternative called Rely that kills weeds but doesn't affect the mycorr.  It is going to take time to get the mycorr established, if you do not till, along with consist incolations for a few years.  To have enough mycorr, it needs time to colonize and reproduce..
 

Kent- I have trouble understanding you.  I put the synthetic fertilizer (N-P-K), or have in the past, down in the Spring, about middle of April, to first of May, springtooth it in - and along with that, I put down pre-emergent herbicide (once in mid-April - Trifurlian - Treflan it used be called) and one when I plant (Stealth), behind the planter, in the plant row).  I plant the crop starting May 15th.  So I would put the fungi and N-fixing bacteria down, mid June, after the plant comes up?  Safe to do that?  I never spray Roundup, boom spray on it, unless weeds really bad, but I do have riders that I spot spray, individual weeds.  Your comments again please.  I can put down dry fertilizer for a slow release if I need to, to protect the soil and the Fungi, and bacteria?     Zack - 80 parts per million or  high syntheic Phosphorus fertilizer and thats only when its applied at the same time. If its established it wont effect the colonization of mycorrhizae. the reason you a are applying it is for more N/P. Slow release, or a 20/20 blend wont effect it at all.

Zack -  The mycorrhizae will be established if you put synthetic fertilizer down in the past or not. If you had the synthetic fertilizer at a really high rate at the same time as the mycorrhizae then there is a chance the mycorrhizae doesnt form. You should be fine applying the mycorrhizae in May. You don't need to over think this process, it will work out.  Dont worry about spot round up sprays, heavy sprays is bad for fungi establishment, but spot sprays will not effect it very much.

Kent - You said the NPK does not accumulate, but it sounds like it does, because of the mycorr.  Or - the mycorr builds up, large enough, expands deep and wide, to service the crops without synthetic fertilizer, like the mycorr is lifting weights, getting bigger?  Zack - Yeah, the cover crop will accumulate NPK, aka nitrogen fixing cover crops, but it is not the myco.  You can still use synthetics, just not more than 80 parts per million of P, while applying the Myco.  Zack - You need a cover crop that has been treated with myco, it could take 3 to 4 years for enough mycorr to build up in the cover crop in order ofr it to be available for your main crop, it takes time.  Carbon is actually stored in the fungi filaments.  Mycorr plays a big role in that, they are like storage containers.

Kent - 2-4-D and diacamba - my chemical man said you could spray those on wheat, at a certain stage of wheat development?  Zack - I wouldn't apply 2-4-D when the mycorr is forming.  Don't know what diacamba is.

Kent - I use Dyna-Grow cotton seed, the company name is Nutrien.  100% of their seed is coated with a fungicide - Evergol.  Asking around, all seed companies do the same thing, the fungicide a different name
I suppose.  Man I have been around the track a few times on this one, half a dozen people never been asked the questions I asked.  Any thoughts on ways around this obstacle?  One NRCS man mentioned the term
- mycoapply - maybe you know what it is.  I have a chisel rig, puts down liquid at any distance from the plant that I choose - maybe let the plant come up, 3 weeks, chisel in the liquid mycorr -
maybe the fungicide far away from the developing root system of the plant (the fungicide coating on the seed) - maybe chisel in 10" from the row of plants.  Just throwing out ideas..

Kent - We're coming out with a liquid myco product, which we can actually ship this month. We us a polymer now that helps the helps the mycorrhizal spore stay active for longer periods. 
Here is a link. Ag side you will need to use 50 ml per acre of seed.  Fungicide Seeds treated with fungicides typically do not impair mycorrhizal development since the germinating roots carry the
mycorrhizae away from the treated seed. I attached a guide on what fungicides will work with mycorrhizae. Also, I attached a guide on helpful tips for fungicides.

Kent:  Shelf life?  Zack: 100% for 2 years, maybe lose 20% in year 3.

From Todd Ballard - Salesman for Nutrien.  - Yes, the fungicide just protects short term for emergence.  It is not a lasting fungicide as a very small amount of fungicide is used in seed treatment.  Sounds like chiseling would work.  We add these two products to cotton seed - Evergol - fungicide and Awaken St - helps with cotton emergence.

Liberty Link is a genetically modified trait in cotton, not a herbicide.  Liberty Herbicide is used on Liberty Link traited cotton, just like Roundup is used on Roundup Ready traited cotton.  Liberty is a herbicide comprised of glugosinate, surfactant, and inert ingredients.  Liberty does not contain any glyphosate.  Glufosinate is nott he same as glyphosate.  Damon Crabtree is the BSAF chemm rep for your area if you would like to reach out to him, is email is damon.crabtree@basf.com.   Brad Stwart - Ag solutions Advisor, BASF.

Rely Herbicide is not labeled for use in cotton but Liberty Herbicides is and should be readily available for the 2023 season.  It can be used on cotton that has the Liberty Link trait.

2-4-D - do not use on mycorrhizae fungi.
