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!
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.
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 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. 😊
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.
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..??
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.
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?
very insightful lecture. Please kindly help me with this question. " Explain the importance of cation exchange capacity(CEC) on soil fertility"? thank you.
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.
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!
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!
We had to watch this for my soil science class! It really made things click for me with the visual representations
The high fives will make me remember cation exchange process FOREVER. No kidding. Well done and thanks for this high-quality informative animation! :)
I have never seen such beautifully explained the concept.
Great work
Love from India
ALL the best
One of the best most efficient videos ever on RUclips...
Amazing, I study Agronomy in Brazil and it was so useful for me Thanks
im studying agronomy too in malaysia.
Fantastic! What a great tool to help clients understand how certain soils need to be fertilized differently.
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!
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!
YUP THIS VIDEO SUPERCEDES THE LAST TEN ARTICLES ON ANIONS AND CATIONS IN AG I'VE READ

We are so glad you liked it. Thanks for letting us know.
thanks a lot for this brilliant explanation of the CEC.
THAT'S THE WAY OF PRESENTING SOMETHING GOOD..!
Awesome explanation in the most simplest way possible. Thanks
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
Well explained. Currently studying soil ecology and I find this video very helpful

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..??
amazing video, THANKS FOR for the learning lab team
it's amazing, helps me with my soil science studies!
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!
I am professor of botany belive me the way you explained is awesome. 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.
Hasta hace un tiempo, había una versión subtitulada en español de este video y no la encuentro ¿alguien podrá pasarme el link?
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+?
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.
That was a great edu video ,got many mysteries cleared today and agricultural info enhanced conceptually ,thnk u .Watching from India .😊
thanks a lot, I didn't know there were vids of such high quality about our little study topic :)
Excellent material for my students in soil science.
Clear info with excellent animation. Well done!
Wow, this was so awesome. I never thought I would enjoy learning about chemistry and yet here I am!! :D
Thank you, great illustrations!
This is so cool. Easy to understand!
Amazing explanation and i love the visualisation :)
Can anyone drop the reference of the cec to determine how oong and how much fertilizer does it need to fertilize the plant?
its a wow! it has always seem like magic till this video
very insightful lecture. Please kindly help me with this question. " Explain the importance of cation exchange capacity(CEC) on soil fertility"? thank you.
Awesome presentation
Absolutely brilliant presentation , i loved the explanation and it made it easy to understand. thank you so much
Glad it was helpful!
Thanks a million , you are an amazing teacher❤
Why are the clay particles negatively charged?
Best video thank you!!!
What an amazing presentation.
OH !
Thank you for your amazing content.
can you alter the CEC in a soil?
Thanks for the video, great aid on electrochemistry..
Very good explanation. Help me a lot in understanding ions exchanging process in rocks..
Can anyone help me how can I summary all of this ... Thanks for reply 😃
Amazing! Trying to explain this gets me so tongue twisted. Brilliant simple and easy to understand. Thank you a hundred time over!
Very clearly explained and well-designed tutorial.
Many thanks!
Brilliant in simplicity and clarity!
How often is fertilisation required? NEVER if you have an intact Soil Food Web
best video I have ever seen
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!
what soil structure provides the best cation exchange and drainaige atthe same time 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 you explain in a great way
