Taking a soils course now and it took me a whole chapter and six lecture videos to get the same information. Brilliantly done, well organized, and I love the faces and high fives exchanged by the cations. I'll never read H+ without imagining it's cute lil face again.
Absolutely brilliant presentation. Wish this had have been around 20 years ago. Should be compulsory study for all agricultural courses! Congrats! Would have made my seminars so much easier to understand!
Can I just say that I've spent hours trying to explain these concepts to clients, but now, I just have them watch this video and I follow up with, "It all makes sense now?" I send clients to this video almost weekly, so you are welcome for all of the views!
I usually don't comment on any video...and this is my first comment ever...no need to say you expained this concept in the most efficient and simplest way possible...Thank you so much...
We are so glad that it helped you. Our mission is to help people learn, and when we find a concept like Cation Exchange that people struggle with and need to understand, we are very gratified to be able to work with content experts to craft an explanation that works for people.
This is great and I really don't understand why this can not be learn at schools in America. Soils are of different types and need different care for them to produce well. This chemistry video was well planned and organized for any normal person to understand. Farmers need to watch this and know that excess fertilizer added to some soil types is not good.
this is really helpful for houseplant keeping too! now i know why it's necessary to mix and match ingredients for potting mix; it's more than soil ph, porosity, and water-holding capacity. houseplant community shall see and discuss this
THIS is the video I’ve needed for a long time! I can actually say I understand cation exchange now. Amazing video that I’ll be recommending to anyone who will listen. 😊
Very nice video , thanks. Which are cations among micro nutrients..?? Does it mean that clay is top nutritional soil as it has large surface area..??? You plant that plant release cation H ,does it after metabolism of water which plant takes..??
very insightful lecture. Please kindly help me with this question. " Explain the importance of cation exchange capacity(CEC) on soil fertility"? thank you.
Great video! I do have one question, however. I recently started studying this subject and was taught that the ion charge and retention of nutrients is associated more with the humus in the soil than with the minerals. Thoughts anyone?
Hi, I’m studying CEC for my ap environmental science class! At 3:52 how come it says more electronegativity + more surface area = more CEC, when at 1:01 it says that particles will leach out if there’s more surface area? Thank you!
I believe that what he is saying is that there is less leaching happening when there is more surface area because with a greater surface area the CEC increases allowing more particles to attach to the soil. In the video, he was just saying that particles leach out if they have nothing to attach to, but particles with more surface area will have less leaching because there are more available sites for the cations to attach to.
What happened to the organisms living in the soil that make up the soil food web. Bacteria, nematodes, Micro arthropods, fungus etc? Seems to be heavily weighted towards chemical intensive agriculture.

Which course? 😅
It's the Kiss principle. Some people are just better at explaining because they focus on the basics.
They aren't trying to teach people.. probably haven't been for a while now
Totally agree with the high fives. Brilliant!

We had to watch this for my soil science class! It really made things click for me with the visual representations

YUP THIS VIDEO SUPERCEDES THE LAST TEN ARTICLES ON ANIONS AND CATIONS IN AG I'VE READ
I have never seen such beautifully explained the concept.
Great work
Love from India
ALL the best
Amazing, I study Agronomy in Brazil and it was so useful for me Thanks
im studying agronomy too in malaysia.
One of the best most efficient videos ever on TH-cam...
Taking ecology this semester in college and we covered this concept. Not going to lie I was very confused but this totally clarified my confusion!
Fantastic! What a great tool to help clients understand how certain soils need to be fertilized differently.
absolutely brilliant explanation. you have a task my friend to educate millions with your style of teaching.
The high fives will make me remember cation exchange process FOREVER. No kidding. Well done and thanks for this high-quality informative animation! :)

thanks a lot for this brilliant explanation of the CEC.

houseplant community shall see and discuss this
Well explained. Currently studying soil ecology and I find this video very helpful
This video is fantastic!!!! I'm studying soil & plant nutrients and needed to brush up on CEC and this was pretty helpful and entertaining.
You email me asap
THIS is the video I’ve needed for a long time! I can actually say I understand cation exchange now. Amazing video that I’ll be recommending to anyone who will listen. 😊
We are so glad you liked it. Thanks for letting us know.
amazing video, THANKS FOR for the learning lab team
THAT'S THE WAY OF PRESENTING SOMETHING GOOD..!
I am professor of botany belive me the way you explained is awesome. Thanks
Excellent material for my students in soil science.
Thanks a million , you are an amazing teacher❤
What an amazing presentation.
OH !
Thank you for your amazing content.
Clear info with excellent animation. Well done!
Thank you, great illustrations!
Awesome presentation
it's amazing, helps me with my soil science studies!
Amazing explanation and i love the visualisation :)
That was a great edu video ,got many mysteries cleared today and agricultural info enhanced conceptually ,thnk u .Watching from India .😊
amazingly presented, Thank you so much
Absolutely brilliant presentation , i loved the explanation and it made it easy to understand. thank you so much

This should be the textbook standard when taking classes in college.
This is so cool. Easy to understand!
Sir you explain in a great way
Very clearly explained and well-designed tutorial.
Many thanks!
Excellent work, the illustrations, the explanations and the sounds are perfect!!. I also looove how you didn't just assume scientists would be boys.
Amazingly done..
thanks a lot, I didn't know there were vids of such high quality about our little study topic :)
Absolutely invaluable information.
What makes you say that?
Very nice video , thanks.
Which are cations among micro nutrients..??
Does it mean that clay is top nutritional soil as it has large surface area..???
You plant that plant release cation H ,does it after metabolism of water which plant takes..??
Wow, this was so awesome. I never thought I would enjoy learning about chemistry and yet here I am!! :D
short and precise thank you sir
OMG what an explanation...........we want more videos like this
Thank you! Check out our other resources at ScienceofAgriculture.org. We are always developing new educational videos and interactives.
Sir please upload more soil science vedios your vedios is more effective for study thanks
We are working on a new video on soil water tension. Stay tuned and thank you for watching!
You just teach me in 5 sec. Thanks a lot . fabulous
So glad that it helped you learn
Thanks for the video, great aid on electrochemistry..
its a wow! it has always seem like magic till this video
Well explained .

Brilliant in simplicity and clarity!
This made it so fun to learn! Thanks
Very good explanation. Help me a lot in understanding ions exchanging process in rocks..
That was great explanation
Teaching like this 👍👍 superb
Just helped me a lot. Thanks
Best video thank you!!!
Bravo ! Best Presentation
Nice explanation 👍
best video I have ever seen
Excellent!
very insightful lecture. Please kindly help me with this question. " Explain the importance of cation exchange capacity(CEC) on soil fertility"? thank you.
Very well explained. I may dub this in my language, Gujarati for our local farmers.
Hello sir, Would you please contact us about this possibility. We may be able to help.
I have got great knowledge. Thank you very much.
Perfect explanation!
Really good video. Thanks
Sort of inspiring story..😁😁 Thanku Sir
You are most welcome 😊
Amazing.,video I ever seen
video like these🙏🏻 great info
Very impressive 💯❤
Great video! I do have one question, however. I recently started studying this subject and was taught that the ion charge and retention of nutrients is associated more with the humus in the soil than with the minerals. Thoughts anyone?
the concept of humus has been debunked and changed to new teaching.
Very helpful video 👍
Glad it was helpful!
I have a question. If there is an Fe3+, would the soil colloid that has a negative charge would require 3 negative ions for it to attach Fe3+?
Hasta hace un tiempo, había una versión subtitulada en español de este video y no la encuentro ¿alguien podrá pasarme el link?
amazing video thank you so much!
This is so useful. Thank you
It's really helpful
Can anyone drop the reference of the cec to determine how oong and how much fertilizer does it need to fertilize the plant?
super helpfull thanks a lot
awesome video, thank you!
Great vedio....
loved this video def helped me understand it much better thanks!
Well done. Cool video!

wow this is an amazing video. Very helpful! ^^
So amazing...
Thanks so much
Why are the clay particles negatively charged?
can you alter the CEC in a soil?
Helpful👍
Good work
Thank you for this masterpiece you human being, I now understand the Cation exchange muahahahahaha
what soil structure provides the best cation exchange and drainaige atthe same time Sir?
What happened to the organisms living in the soil that make up the soil food web. Bacteria, nematodes, Micro arthropods, fungus etc? Seems to be heavily weighted towards chemical intensive agriculture.
Thank you for pointing out the importance of living soil. We have plans for future videos on soil microbiome!
How often is fertilisation required? NEVER if you have an intact Soil Food Web
Can anyone help me how can I summary all of this ... Thanks for reply 😃
excellent
WOW, HOW AMAZING YOU ARE!!!
