Ep.1 Mycorrhizal Fungi + Biochar = Double Good...Right? 

Word.

I can't find it now, but back in 2018 when I first started to really dig in and research this I even found that the soils from the Amazon and the Black soils of Africa had this same trouble with Mycorrhiza. AM is my primary go to, so that is why I only use wood charcoal in very low amounts by volume in a nutrient channel about 6 to 8 inches below the soil surface.

I’ll have to look that up. That’s interesting. Another aspect is wildfires. I read somewhere I think Iowa has black soil because of wildfires over thousands of years. I think volume is one way to measure it. But if you grind it finer then your volume shrinks. I guess it’d be consistent for measuring if you have similar size charcoal each time. I know a biochar company in Cali they sell it in a one ton sack. And you can mix it how you want. I think for farmers they mix 3/4 biochar and then 1/4 worm castings for $400 a ton bag. I can’t remember if they sold it by weight or volume but they did measure the water content so it’s consistent so that way you can compare results over time. I think they use it to get toxins out of the soil like cadmium so cancer causing things don’t go into the food. What was your low amounts? Like one part charcoal and 9 parts other stuff? And ya it’s probably good to have it deeper in the soil. I think if it’s ontop in the summertime the black would heat the top of the soil a lot which is bad

I cannot thank you enough for pointing this out! I only had a video for those unsubscribed to the channel, and the rest was blank and I had no idea. Will be eventually adding some play lists in the coming weeks. Fun stuff in the works! :)

In another experiment, I inoculated (2) 5-gallon buckets of Biochar in ‘Bio-complete’’ compost extract for 36 hours. I then tilled that into about a 1,000 SF, yes tilled to more fully mix it in. I also tilled in a very heavy amount of excellent cow manure based organic compost, so there should be lots of microbes.

55555!!!

In the research I have done on this to date, Biochar is definitely not a 1 size fits all kind of amendment. It may be beneficial in the way of water retention for poor sandy soils, but honestly that is about it. I use the wood charcoal (not Biochar) to hopefully absorb heavy metals. I also use it at the bottom of my bins for Black Leaf Mold. The variation in heat during Pyrolysis definitely has an effect as well, but I have not seen enough studies to conclude one way or the other on which feedstocks are best. There seems to be some indication that Chicken manure is really good as a Biochar, but the study was limited.

@@NorthernThaiGardenGuy definitely not one size fits all. I had heard some research doing chicken manure biochar I think it was on one of Cornell‘s webinars posted on RU-vid but I haven’t had a chance to go through it yet.

@@NorthernThaiGardenGuy you mentioned poor sandy soils, I’ve read also that biochar can increase drainage of hard clay soils, while increasing cations Exchange. I think much research is needed but that it has been proven to be beneficial to a variety of soils, though I have not researched its capability to absorb heavy metals. 🙏🏼 for sharing you knowledge

@@fasi247 it’s been a while since I read up on the exact science of how it is absorbed, but my guess is, if you relied solely on BC to remove the h. Metals you’d be correct, eventually, the char does breakdown and if no other process has changed the chemical make up of those metals, they would release it back over time as it degraded. However, I believe AMF alters this chemical structure , thus the H. Metal wouldn’t release back into the soil as it’s self. “Phytomediation”

@@fasi247 Arbuscular mycorrhiza fungi. I think there’s a lot of unknowns around AMF on it’s transporting and uptake of metals. I have heard of people mining heavy metals from plants it’s possible that the same could be done with the fruit bodies of the fungi. I think there are studies out there, though of fungi, growing on superfund sites that report declining levels of various metals and high-level toxins in the soil, suggesting that the fungi is breaking it down in someway, but that’s kind of getting to the horizon of my understanding. . My thought with AMS is that a lot of the holes in bio char are too small of a micron for most plant roots however, AMF can fit into these carbon structures and transport. The nutrients that is locked in that carbon structure to surrounding plant roots so potentially if you had a high AMF content in your bio char mix, and then you planted Symbiotic plants potentially the AMF could transport, the heavy metals absorbed in the bio char to the feet stock that then could be removed. Just a theory if the AMF isn’t digesting the heavy metals.

🙏

Good idea for the future. The current spot is doing quite well and does not look to have had the same issues that were experienced by the AGU study back in 2014.

Thanks for stopping in! Hope you enjoy things (I have been a bit slowed by the nonstop rain this season, but have new content in the works).

@@NorthernThaiGardenGuy I'm in the Hua Hin area, we don't get it nearly as heavy as you guys up there.

@@juguruteacher6204 I'm up between 3 different Provinces right now just depending on where "C" is at these days. Hope you guys stay safe and thanks again for being out here!

I probably should have qualified that without painting with such a broad brush. There are well over 200 species of Trichoderma (with more being discovered every year). Some of them are more predatory than others and will outcompete other Fungi (like Mycorrhizae). That was the reason I mentioned it, and I should have done a better job with what I was talking about. Thanks for pointing that out!

Well - I do not use any chemicals or synthetics in my soil. I understand they add boosted growth and all, but they also kill off the microbes (which is what I ultimately want more than anything else for my soil type). As I was sharing in the video, so long as the Mycorrhizae is at a separate level in the soil to start with, I don't think the pathogenic behavior is nearly as bad or present at all. Johnson Su is a terrific way to get fungal compost and is better than any nitrogen fertilizer when compared side by side. Takes less in a compost tea to do what nitrogen needs to do in large amounts.

I use it this way for a very specific purpose and that is for the uptake heavy metals. That's why it is dry and not inoculated. Sorry for my late reply!

Fantastic yes I totally agree #biochar is perfect for heavy metals.

@@NorthernThaiGardenGuy Oh okay... I get it now... The charcoal is a protective measure to absorb potentially harmful things inside the soil... Very smart.

@@busyrand In my situation that is the only reason I use it, but I have just this year added something else to aid in that effort - Chitosan! 🙂

@@NorthernThaiGardenGuy Interesting...

That is the plan eventually, but a little later down the line. It's not really dry here very often and right now I need to focus on getting this soil healed.

@@NorthernThaiGardenGuy Sounds like a good plan. It would be interesting to see how you heal your soil. Mulch also helps the fungi to spread and is even better with some chicken manure on it. Lowers the smell too.

@@minibite3 I use Natural Farming inputs from KNF and JADAM. Will have some upcoming videos on this in the not too distant future.

Thank you very much and enjoy!

It's a good question. I am going to try using Chitosan to inoculate wood charcoal and see if it has positive effects.

Very true!

Sorry to hear that, and yes it is.

My grandpa used to have glass hothouse in his backyard. After he died we had to remove it (it was in bad shape after a hailstorm). Two decades later we still find pieces of glass in the grass. Not only moles dig them up, but soil itself drags them to surface after every winter when it thaws.

Rent only.

I would have loved to do that, but I am short on ingredients right now.

@@NorthernThaiGardenGuy yeah that is the only thing about knf and jadam, so many ingredients and mixing things and time involved.

@@GroProOrg But it is a lot more fun and if I am going to pay for stuff I'd rather it be my own ingredients than giving it to big Ag.

@@NorthernThaiGardenGuy oh yeah and please keep sharing all your work with us, it is very important and appreciated. Thanks so much!!!!

This is Thailand (not the US). We have a well on the property.

Yeah - no disrespect, but that's actually not true. It's a myth that's been around far too long now. The problem is that the iron that gets produced by rusty nails is iron oxide. This is both insoluble and mostly inert. It provides no benefits to the plants in your area, but could potential be hazardous to the gardener if they gets scratched and end up with Tetanus.

In this particular case they do not add (nor take away) anything from the main issue. The communication lines of the Mycos are snipped by the Biochar, but I think the way I separated them at different levels in the soil has worked. Will do a follow up to this in the beginning of 2024.

Word! :D

Tell me more about it
