Visualizing Soil Properties: Dispersion and Flocculation

This demonstration shows the effect of calcium (from gypsum) on bringing dispersed soil particles together as aggregates to aid in reclaiming soils with high levels of sodium.

[@nandanmendapara8604]

I had seen many videos of flocculation and difloccultaion but nobody can teach like you....great explaination and example of farmer's field...thank you sir...

[@langstonmarcos6668]

i guess it is kinda randomly asking but do anyone know of a good site to watch newly released series online?

[@justusandre4158]

@Langston Marcos I use flixzone. Just google for it :)

[@starnova2311]

Who disliked this video? It is literally what the title says lol

[@K1dPhresh1]

This clarified dispersion and flocculation for me. Thanks.

[@airmen5]

Me too. I really enjoyed watching the clay particles settle out over thirty minutes. Very clear visualization.

[@lalitharamakrishnappa2066]

We have clay rich soil which doesn't drain out water when it rains heavily in our coconut farm. Manually we were removing water. Then I added Gypsum, red soil and organic manure mostly horse gram plants manure. After a month I am seeing good results now. Water drains away.

[@ayushsuyayush]

My professor missed this portion in class so I am going to give the whole class on flocculation and dispersion. Thanks :)

[@netskie8342]

THANK YOU SO MUCH SIR. This demonstration explains very well. Finally understood the logic of gypsum.

[@rendyrosales786]

How much gypsum for 1 hectare earthen pond, i have high turbidity due to rain and have shrimps in it, with salinity of 18ppt,i have average of half meter depth water

[@GriffenNaif]

wouldn't you poke holes in your pond with gypsum? Turbidity do to rain run off into pond... you can create a swale outside of pond to slow and settle water before it enters pond

[@CyclingWanderer]

Thank you sir for amazing explanation..

[@burnsm2012]

I did this test at home with clay soil thst sheds water. My problem is after being stirred with distilled water the clay did perc to the bottom

[@CyclingWanderer]

very nice demonstration..

[@nandanmendapara8604]

very well explained....concept is now clear....thank you...

[@xxpowwowbluexx]

This is awesome. Thank you for the video! A question, though: does gypsum kill or negatively affect the microorganisms in the soil?

[@datsuntoyy]

I've heard it helps IF the soil actually needs gypsum. It will help the mycorrhizal organisms get the air the need. It can also loosen up the soil so worms can move through it. Keep in mind if your soil does not need gypsum (get a soil test) it won't do any good and can actually hurt.

[@missanna208802]

Oh my god, I love you so much. Thank you!!!

[@dakshinatamang7527]

well explained👍

[@yusufalbalooshi2723]

Hello dear, I am from Bahrain. I need your advice on treating soil salinity and sodium and calcium carbonate from agricultural soil. Thank you very much.

[@nimalbandara3573]

Great demostration

[@vistagraphsnet]

I am digging a shallow well and at eight feet hit hardpan. Can I pour gypsum in to break it up?

[@billnolde4359]

No. Large amounts of gypsum must be tilled deeply into a soil volume to have a flocculating effect.

[@xxpowwowbluexx]

So, what can I do with my fescue lawn grass growing in a layer of topsoil that is sitting on top of solid clay dirt underneath? How do I flocculate that clay underneath the topsoil and grass?

[@imaliktay]

good explanation

[@marielachoquefuertes6024]

Thank you, i need the same video in spanish, so good translate of youtube. Congratulation.

[@murayray7614]

This is one of a good solution for soil treatment in my garden. Tengkyu very much sir 😁😁😍😍

[@46vishalkumar53]

Reallly Great, thanks for this distilled video😁

[@delbertbragdon8953]

THANK YOU SIR!!! A VERY GOOD DEMONSTRATION OF THE CONCEPT OF FLOCCULATION AND DISPERSION.

[@dinosaur0073]

Very valuable info. Thank you..

[@yusufalbalooshi2723]

Thank you dear for excellent information

[@puttinagendra]

Very nice presentation

[@bjb6577]

Thank you. This is so helpful!! God bless u Sir!!😇

[@carlosdeandro7046]

What happens with clay and gypsum when dry ? He is together or separated ?

[@MrAbakhamo]

Thank you sir for comprehensive information

[@billnolde4359]

I appreciate the scientific explanation of the flocculation v. dispersion aspect by Dr. Walworth but actually it can be misinterpreted. By addressing flocculation of sodic soil with gypsum as the "silver bullet" he used a demonstration of 1:1 volume to volume gypsum to soil to accomplish the flocculation and with distilled water, no less. This is impossible in a real world agronomic situation, either in agriculture or, especially, with topically applied gypsum for ornamental landscape soil management. I absolutely agree that calcium is the element to use in providing the solution for flocculating sodic soil, but there are much better calcium sources than gypsum.

[@xxpowwowbluexx]

Bill Nolde, OK, like what?

[@datsuntoyy]

Ditto, like what?

[@GriffenNaif]

Wonderful knowledge please do a video

[@akhilmylapore5758]

i tried flocculation process using Sodium Hexa Meta Phosphate (SHMP). It did work and all the soil(soil - bentoniteClay) particles setled down. But now i need to know how much amount of SHMP i should use for 1 Metric Ton of soil (soil - bentoniteClay). Hope my comment makes sense! and if anyone knows please help me out with this.

[@napalmunderwear9902]

Maybe not a good idea because it will also release a lot of phosphate in any runoff. It might cause eutrophication in any adjacent ponds. and lakes.

[@immortalmonsterhybrid975]

@@napalmunderwear9902 not sure if its a good idea thwn to use this method for extracting clay to make pottery per say.

[@sherkonikbakht1838]

Very Brief and usefull

[@immortalmonsterhybrid975]

I know it lets clay come together and allows water flow to seep through. Though is this for making clay or is this for plants. I tried laundry detergent dont think it worked and i heard of dish soap. Not sure if this will be ok to do for getting the clay. Excellent video by the way. I guess im asking if this method can be used for getting out clay from samples dug up? Thanks

[@sanidhyasingh1605]

Great ❤️💯

[@donjayamaha6174]

When we add gypsum to clay soil it aggregate what's will the aggregate particle size of soil

[@77_rajasthan]

Great 👍😊

[@dhavaldwivedi]

Excellent

[@amitrakshe5773]

Nice presentation

[@shaungarbry88]

So after the clay has flocculated, it is the air, water, etc between the larger aggregates that keep it from compacting into a tighter mass?

[@larablom7444]

This is a really helpful demonstration. Thank you.

[@simharowdram-hindutva4188]

Thank you this was very helpful

[@nmsuaces]

Glad it was helpful!

[@sakhumzigumede9400]

finally understand, thanks for the demonstration

[@adamowaisi2186]

the last hour of reading a book has been a lie! you are the man !!!!!!

[@alasmohamed3534]

amazing explanation ever seen. thanks sir.

[@HiteshPatel-hq7xp]

What is the name of chemical

[@nmsuaces]

gypsum, calcium sulfate dihydrate

[@enstamud]

Great video. Is there a sheet to accompany this? Details on protocol. Thanks

dankie maneer...

[@ciccioformaccio7527]

Unfortunately you use a lot of very imprecise terms. Chemistry is a precise science that requires precise and appropriate terms.

[@SteveDavies01]

Could you elaborate on this "imprecision" please?

[@datsuntoyy]

maybe if he's talking to chemistry students. Takes a real professional to explain science so average people can understand.
