The Rhizosphere: an interaction between plant roots and soil biology

- Опубликовано: 6 сен 2024
- In this episode Octavia takes a look at the Rhizosphere - a term given to the thin region of soil around a root hair where interactions occur between the root and microorganisms within the soil. Using the energy from light, the plant converts carbon dioxide and water into sugar and oxygen (6CO2 + 6H2O ⇒ 6O2 + C6H12O6) - this is photosynthesis.
Rather than using all this sugar for growth, they secrete some of it into the Rhizosphere, along with proteins and other substances - these sugary solutions are known as exudates. You might think that this is a waste of valuable energy, but they are actually attracting a microscopic workforce into the area, a colony of bacteria and fungi that help the plant extract nutrients from the soil that would have otherwise been unobtainable to the roots alone.
This marvellous symbiotic relationship leads to more complex interactions; it acts as a disease suppressant for the plant and forms the foundations of the soil food web. This web is vital for nutrient cycling and supports the growth of new life.
Modern farming practices can damage this soil food web, often destroying the delicate interactions between plants and their resident microorganisms. These practices are having devastating effects upon plant health, crop yields, soil stability and wildlife and are not currently sustainable.
At 59 Degrees we are paving the way forward for a healthier soil community. We believe that in order to promote healthy, happy plants, we need healthy, happy microorganisms.
We grow communities of these unique soil microorganisms that you can use directly in your soil and on your plants - from salad crops to mighty oaks. By adding this beneficial life to your soil you will transform the health of your plants.

Underrated explanation.
It's amazing how many self-styled RUclips garden gurus with big followings don't understang this yet.

Concise, articulate, informative. Thanks!
Thank you for making this quick and cute I was just doing my plant science lecture and understood nothing till I saw ur video!!!
You are so welcome!
Helped a lot. Crystal clear explanation. Cheers!
Thank you, a big hug!
This ia all going to get more interesting with the recent discovey of a rhizophagy feeding cycle between plants & micro organisms.
Very good and well made video! Thank you
Pio Pajarillo hey! And thank you for your kind words! It means a lot to us!
Such a high quality video, thanks!
Great video. Thank you!
Excellent video. Geological history of clays is very interesting. More please.
Rod S thanks for your message! Always nice to hear good feedback. We are hoping to get more out, as we’re becoming increasingly aware of how little good information is out there. Keep tuned in and we’ll get more vids out soon!
How is it you only have 356 (now 357) subscribers?! Great content, fantastic visuals.
Thank you for your lovely comment Elizabeth!
Well done.very informative
These videos are great. Keep it up!
Keep making videos!!! Save the world!!!
Yes!! Will do. Thanks for your comment and support!
can i directly foliar spray or water my plants with sugar mixture..?
Love your Videos, just found them Dec. 25 2022 when I woke and and thought "what is humas"
This video deserves more attention! Really good!
kriptoniteXD thank you so much! Your comments really mean a lot to us!
@@59degrees98 I'm very confident that I'm witnessing a future big RUclips channel! Thank you for providing us with such interactive material!
@@kriptoniteXD Thank you! That's really kind. Thanks for supporting us too!
Kindly upload more video
Excellent...
Great presentation and delivery.
thank you for making ecology and plant science so sexy. A very great work and a hypnoticly nice accent😍
Violetta V thanks for your lovely comment! So great to hear from like minded people.
Appreciating, thank you 💚
Rebecca Jo Steelman thanks for watching!
apreciate it!
Thank you!
your work is amazing. thank you
Thank you
very informative, thanks!
rana farrasati thanks for your lovely comment!!
this was really well done!
Cool... Is it the brother of mycorrhizal? And also very nice accent :)
Yes, it is! Mycorrhizal fungi form the symbiotic relationships with plants and trade nutrients for sugar!
Thank you, well done
Carina Byrne thanks for watching!
Why you are not making new videos????
Thanks😊🌹
Mogambo sagar yt thank you for your message! All the best, 59degrees
subscribed!! well presented video!
Next time somone asks me what plant food they need. Im just gonna show them this video
so much love from me
Without the soil no life fungi etc. Without the life in the soil no soil. When are people going to get it?? You can’t have one without the other. They had to be put there at the same time. Just like baking a cake flour eggs sugar and butter take one out or to much of one it’s ruined. Life didn’t evolve it was created like a cake. You see a cake you ask “who made it?” Not how did it evolve?
So true!
Hi Octavia, we love what you are doing. Let us know if you might want to be a guest speaker at our Speaker Training Course www.kisstheground.teachable.com
Hi Finian! Thank you for your lovey comment. I've just been browsing Kiss the Ground's website - looks like a fantastic initiative - on behalf of 59 Degrees, I'd love to be involved with your course. All the best, Octavia
Does 8:00 Pm PST work for you to join a zoom call? not this week but the following week.
Hi Finian, so sorry I've tried to private message you, but it's not working. Is there an email address I can get you on?

This is a great video that I will use as an intro to the rhizosphere in my course. I cannot help but share that I wish the comment 'modern farming practices are detrimental to this web' was not included as it is not supported with any evidence. As it is stated, it's vague at best and misleading at worst and I think it leads to more misconception than clarity with respect to the current state of the research. Clearly, fertilizing practices, farming methods, and the addition of chemical agents to control pests affects microbial community size and structure. However, it is not as easy to determine whether these changes are 'good' or 'bad' to soil health, microbial community health, and/or crop health. I will provide my students with some of the research about this topic so they can put the statement in this video in context. Please consider revising the video to clearly indicate the evidence used to support the conclusion made or remove the statement completely.
Agreed great video. The generalization that modern farming practices are degrading and degenerating our soil is accurate. In the US we are losing 4 tons of topsoil per acre per year average on our farmland. Top contributors: Tilling, Leaving soil bare, overgrazing, heavy fertilizer and pesticide use. I agree it would be helpful if she explained how these modern practices are causing harm but as a general point, it seems valid to me.
Tessa Durham Brooks do you work for Bayer / Monsatan ? There is loads of evidence that modern ag destroys soil life. If you spray a fungicide what do you thing it does to soil fungi?
