Cation Exchange
Вставка
- Опубліковано 12 вер 2016
- Not all soils are created equal. Chemistry helps agriculture succeed in a variety of environments. This video explains how soils (often negatively charged) interact with nutrients (often positively charged) through cation exchange. The cation exchange capacity (CEC) of a soil determines how frequently and in what doses it should receive fertilizer.

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
I have never seen such beautifully explained the concept.
Great work
Love from India
ALL the best
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
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.
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!
absolutely brilliant explanation. you have a task my friend to educate millions with your style of teaching.
Fantastic! What a great tool to help clients understand how certain soils need to be fertilized differently.
Amazing, I study Agronomy in Brazil and it was so useful for me Thanks
im studying agronomy too in malaysia.
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
thanks a lot for this brilliant explanation of the CEC.
Well explained. Currently studying soil ecology and I find this video very helpful
THAT'S THE WAY OF PRESENTING SOMETHING GOOD..!
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
Clear info with excellent animation. Well done!
Thank you, great illustrations!
Thanks for the video, great aid on electrochemistry..
Very good explanation. Help me a lot in understanding ions exchanging process in rocks..
amazing video, THANKS FOR for the learning lab team
thanks a lot, I didn't know there were vids of such high quality about our little study topic :)
I am professor of botany belive me the way you explained is awesome. Thanks
Wow, this was so awesome. I never thought I would enjoy learning about chemistry and yet here I am!! :D
it's amazing, helps me with my soil science studies!
Excellent material for my students in soil science.
Perfect explanation!
This is so cool. Easy to understand!
I have got great knowledge. Thank you very much.
its a wow! it has always seem like magic till this video
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.
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.
Great video
For better understanding of concept
Thanks a million , you are an amazing teacher❤
Bravo ! Best Presentation
OH !
Thank you for your amazing content.
loved this video def helped me understand it much better thanks!
amazing video thank you so much!
Amazing.,video I ever seen
video like these🙏🏻 great info
Absolutely brilliant presentation , i loved the explanation and it made it easy to understand. thank you so much
Glad it was helpful!
This is so useful. Thank you
This made it so fun to learn! Thanks
Awesome presentation
What an amazing presentation.
Best video thank you!!!
Thank you
Really good video. Thanks
Amazing explanation and i love the visualisation :)
Sir you explain in a great way
amazingly presented, Thank you so much
Excellent!
That was a great edu video ,got many mysteries cleared today and agricultural info enhanced conceptually ,thnk u .Watching from India .😊
Amazingly done..
Excellent work, the illustrations, the explanations and the sounds are perfect!!. I also looove how you didn't just assume scientists would be boys.
it is simple and so hopeful.
awesome video, thank you!
short and precise thank you sir
AWESOME!
Just helped me a lot. Thanks
best video I have ever seen
wow this is an amazing video. Very helpful! ^^
Very clearly explained and well-designed tutorial.
Many thanks!
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+?
Thanks so much
Amazing! Trying to explain this gets me so tongue twisted. Brilliant simple and easy to understand. Thank you a hundred time over!
Brilliant in simplicity and clarity!
Amazing video.
Can you tell which editor or video maker you used ?
Well explained .
Thankyou .😊
Thanks!!!
Thanks a great video
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!
Well done. Cool video!
brilliant
thanks a lot
That was great explanation
Absolutely invaluable information.
What makes you say that?
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.
best video
You just teach me in 5 sec. Thanks a lot . fabulous
So glad that it helped you learn
Amazing
Thank you so much :')
How do the nutrients become cations in the first place? I don't know much about chemistry. Are they neutral until the water comes? or were they positive for some reason to begin with?
Great vedio....
So amazing...
Fantastic
Great stuff. Thanks for the visuals
Glad you enjoyed it!
super helpfull thanks a lot
Awesome
Good work
Thanks sir
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..??
Hasta hace un tiempo, había una versión subtitulada en español de este video y no la encuentro ¿alguien podrá pasarme el link?
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 impressive 💯❤
Nice explanation 👍
GREAT 👍
What text book can I get to learn more about this process in soils???
very insightful lecture. Please kindly help me with this question. " Explain the importance of cation exchange capacity(CEC) on soil fertility"? thank you.
excellent
very helpful video :)
can you alter the CEC in a soil?
