One major problem with this video is that you show a soil profile with a very clear white E horizon - horizon of eluviation - and you indicate that it is a B horizon. E horizons form under trees and forests and they are areas with high sand content and low OM and low nutrients - accounting for the white color.
+Mary P Thank you Mary P for making that distinction, but I don't know if it is a major problem. The E horizon is sometimes lumped in with the A horizon, where then the A horizon is split into A1 and A2. I think for the scope and sequence of this course (NYS Regents Earth Science) which the videos are geared towards the concept of knowing that the soil profile changes in depth due to a number of factors is most important. My pedology skills are not the best, and I do find it to be a tough area of study. Thanks again.
I THINK THIS VIDEO IS JUST THE ONE I WAS LOOKING FOR MY LESSON ABOUT SOIL, I WOULD LIKE SOME DY TO PUBLISH SOMETHING LIKE IT WELL DON E AN CLEAR THANKS
The whitish horizon is an excellent example of the E horizon, a layer in which eluviation has occurred, it is NOT the B horizon. The B horizon is below the E, and is where illuviation has occurred. Must question this "teachers" credentials?
Hello Rich, thanks for the feedback and the information. I am by no means at all a soil expert, and find it to be a tough area within the sciences. But for the scope of NYS Earth Science and my students it is more important to realize there are distinct layers within the soil formed various processes. I hope you can understand this and forgive me of this mistake.
Now I feel bad, hope I didn't seem too harsh. Glad for your understanding and your dedication to teaching. I too am not a Soil Scientist, just an Environmental educator...a 'jack of all and master of none'. Props to you and any one who accepts criticism and then uses that constructively. I'm pleased to be corrected and or educated too. I do tell kids "I don't know, and or try to work it out to, here is what I think" I then research for the correct information. It is wonderful when we can help each other continually become better.
I like teaching concepts, as they can be applied to a broad spectrum. e.g. While it is nice to know the binomials of plants, it is more important to know why and how they live where they do, and what they do. One can then infer how another plant, is what it is and why, and how it works where it is. Pretty cool when a student puts it all together and gets it.
Disclaimer-Doing this for an University English class. Don't take this to heart. Ignore it if you can. This source represents bad information being spread to students. This is too shallow of an explanation for soil formation. The 5 mechanisms for soil formation such as parent material, climate, biota, topography, and time are poorly explained. It's hard to explain pedogenesis, but it's necessary to use more than a 4 minutes to explain something this complex. I would not recommend this for a college students trying to understand soil formation.
Thank you, I missed an entire first year worth of notes and found this which is part of agriculture, thank you so much!
Awesome!
Thanks for putting this up.

Jasimul Haque very good
this was a good video and it will help me on my test thanks
Thanks for the vid! My son really needed it!
Glad I could help!
this was the video i was looking for.....
thankyou

Wow!
10/10, my family doesn't have enough money for education!
Nice

Dude turn ur caps lock off geeez
Tomorrow is our test in scrince
science****
Same here...even though it’s three years later
Ilove
Soil🍇
... chill bruh...
Oh my God is good night
Sir a ques for u that description is not very good improv it
improve****
I love science 😘😘😘😘
@Claire Mitchell i hate you

he is make our a ful
me-realizing the most recent comment was 3years ago
plz like
The only thing I enjoyed was he was quiet for 5 seconds!
When?
the only thing i enjoyed was that you werent here
This was stupid
your stupid
i hate scholl
I HATE SCIENCE!!!!!!!!!!!!!!!!!
i hate you
