Water movement in the soil

- Through a serie of small experiences, this video will show the basic principles governing water flows.
A video inspired by Gardner W.H and Hsieh J.C., Water Movement in Soils (vidéo), Washington State University, 1959.
This is very informative. I am amazed at how much time and effort is put into study these things. Surely even the set up requires pain staking attention to detail.
Came to figure out how to better water my crop but instead found a deep respect for soil and its intricacies. This video is gold, thank you so much!
Very well done, thank you for re-making it.
Awesome video!! Thanks for putting this together and for sharing!!
Great remake of the originals. Thanks for doing this and making it available on youtube.
I come back to this video every once in a while. It is of such great pedagogical value! It really helped me with the understanding of soil physics. Love that you included the example with aggregates, just goes to show how the soil properties are not only dependant on texture, but also structure. Thank you very much!
Outstanding explanation, Thank you very much!!
Que maravilha!!! Obrigada por compartilhar.
superb depiction of basics of water movement in soils
i have been toiling with different kinds of irrigation methods in my sandy field for some time now . Really informative Thank you
This is golden!!! I'm am currently doing a master's thesis looking into moisture migration in grouting and tile adhesive in bathrooms walls. This video shows an excellent representation into the behavior between materials with different permeability and porosities. I can highly relate to the observations regarding the different layers. Thank you for this, and I will contact your University to ensure proper citations. Thanks from Norway!
This is fantastic THANK YOU!! GOOD WORK
nice ..good work
i think this can be very helpful for farmer
The absolute best video!
As a civil engineer this is fascinating
Thank you. Very well done.
Thank you for the video. I'm about to start a grafted finger lime garden, and didn't know what sort of soil to use. I think I'll go with sandy loam ("portulaca-mix") soil now instead of the 5-in-1 soil commonly found over here.
Thank you for the video and the data!
Thank you for this video. It is very informative.
impressive video and study 👌
GREAT video!
very good information, thank you
Did anyone take into account the compaction layers that were created between the glass plates? This study is actually a great representation of the erosion issues humans have had in the entire history of agriculture with waterlogging on top of compaction layers created by humans.
This was like a month of classes in 15 minutes.... English isn't your first language and you can still teach multiple magnitudes better than most American professors
that was amazing. Thanks
Thank you so much for such step by step demonistration. Would it be okay if I use the video for my students?
Good science. Salute.
Bien fait!
Fantastic explanation
Thank you!
Thanks for great info
excelente vídeo
Merci pour l'upload
thank you thanks!
Nyc experimnt.....help us what type of foot should we use... And aware us different soil absortion process
This video is very good.
I would like to reproduce your experiment with a numerical code. Did you measured the hydraulic characteristics of the soil you used ? Thank you in advance for any help.
Cool video and experiment XD
Would love to see a Sandy soil over a straight layer of Sandy loam. Does that infiltrate better than Sandy loam over clay
Dont know how i ended up here but the water avoiding the sand is pretty cool
I love her voice ❤
great explanation
Helpful Information!
Liquefaction?
Thank you for this video. love the work your doing.. I have a question why does the water move thru the loam faster then the sand?
porosity
Por favor, seria genial que lo subtitulen.
Very helpful
👏👏👏👏👏💗💗💗
are we seeing some swelling in the clay loam at 4:41 ?
woow
when a cloth touches water and water starts to move: does this fell in the capillarity mechanism?
Yes, adhesion and cohesion forces act together in capillary causing upward movement of water through cloth
Inspired by? The script is identical to the old WSU video.
Yes, it was well written. I can understand that they were inspired by it.
High IQ gardening theory crafting:
Make a channel of sand underground under each row of vegetables and have the sand channel come up like a pipe in different spots. Pour water into these sand "pipes" and the water should flow under the plants and hydrate the surrounding dirt from the hydrostatic pressure. Significantly less evaporation, but more work to start off.
Lack of water holding capacity can be combatted with CARBON
love her accent lol
irrigation+rainfall = evaporation + transpiration + runoff + leaching
Which one of these processes do Farmers really have control over during the growing season? If you have the ability to irrigate your sandy soils and water is cheap and plentiful, then you are fortunate and have some control on the left side of the equation. If you do not have irrigation, you must look at the factors on the right side of the equation to see what can be controlled or minimized to benefit your crop. Evaporation from the soil surface can be reduced with mulch or leaving crop residue on the soil surface. Transpiration is a function of the plant leaf surface area and the weather. Runoff is or should be minimal in sandy textured soils with high percolation rates.
This leaves the leaching of water out of the root zone as the #1 controllable loss of moisture to your crop. Interrupting the downward movement of moisture in your soil by installing a "smart" barrier can greatly reduce the leaching of water and nutrients. SWRT subsurface membranes detain/retain up to 90% of irrigation or rainfall in the root zone for crop use by disrupting the gravitational movement of water in the soil while still allowing excess water to percolate and do not create anaerobic soil conditions.

soil science gang rise up
hard to hear the ends of your sentences.
Also, you are not showing us any soil. You are showing us dirt
inspired is the new plagiarism
"The practice of taking someone else's work or ideas and passing them off as one's own." The previous work was clearly cited. This is a new, high quality production of that work, which was originally made at a publicly funded university. This is not plagiarism.
Yep. Great remake.
You must love Jehovah your God with all your heart and with all your soul and with all your mind and with all your strength. You must love your neighbor as yourself. Jesus the anointed is Lord! Repent and be baptized and believe the Gospel.
She literally, word for word, stole this video made 3 years prior.
We have clay soils that absorb water at fast rates because it is no till forming large aggregates over time When not dry the absorption is faster. It is like a moist sponge over one that is dry. With many acres being no till in modern agriculture your experiments are not true in the real world.
eeek the accent is jarring
Yah, my head is exploding. She's probably fluent in three languages and can get by in two or three more. Really shameful accent.
