Hey, I'm new to editing Wikipedia, but I just want to point out tht the Stratum link in describing soil horizon C links to aa linguistic article and that probrably isn't right. — Preceding unsigned comment added by Chocfudge ( talk • contribs) 07:34, 10 February 2019 (UTC)
Thanks, I removed the link. There is no wikipedia article dealing with soil substratum. The article 'Stratum' is not pertinent either because it discusses geological stratification. One could also delete the word 'Substratum' as this term is not commonly used in soil science. Eleutheropodic ( talk) 10:10, 10 February 2019 (UTC)
what are the different type of soil horizons and there characteristics?
I'll look into it. Also, we could get a picture of a cross section of soil with horizons, eh? Lotusduck 19:37, 25 January 2006 (UTC)
Woah, look at that. I think I answered your question. However, someone has to do soil horizon formation, and merge with Horizon Soil. I'll get right on it. Lotusduck 21:39, 27 January 2006 (UTC)
With ever growing and changing terminology, this page does need references. Also, I have made some style screw ups. However, I am still proud of what I just did. Maybe one day someone will fix it up right.

soil is unconsolidated material at the earths crust.
eluviation = loss of materials illuviation = gain of materials
B.E (brown earth)
litter layer fermentation layer organic layer A horizon
.biological active mull .humas .mineral matter
B horizon
.lightly coloured .weakly illuviated
C horizon
. basic parent material eg- clay loam
podsol
litter layer fermentation layer organic layer A horizon
.mor humus or raw peat stronly eluviated ash coloured . mostly bleached mineral grains
BF (iron-pan) often lass than 1 meter thick
B horzon
.strongly illuviated with iron, humus and clay
C horizon
.acid parent material

Launched a major revision of the article, added a bunch more detail and corrected a few factual errors. This still needs a lot of work - there's no mention of European systems of horizon description, and I don't know enough about the US system to be able to discuss it in sufficient detail (to anyone who is familiar with it: help help!). Due to the number of ways one can describe horizons, I think this article is always going to be a pain in the ass to manage and may eventually have to be split into an article for each system, perhaps leaving this one as a basic intro/start point. It also needs more linkage to articles on various soil formation processes, many of which haven't been written yet. Leobrien 07:08, 12 February 2007 (UTC)
Hi -- I don't have any prior knowledge of soil layers, but I think that some more crediting / attribution to the U.S. Dept. of Agriculture would clarify things for the reader. I understand that the illustration with O-A-B-C layers is public domain, and you don't "have to" give them credit necessarily, but a) it seems to me that it would help the article if the illustration was clearly identified/credited to the U.S. dept of agriculture, and b) the illustration is clearly a creative work itself and it would be very natural to credit it specifically to someone by name or to the organization if the artist name is not available. Several lettering system variations are refered to in the article, which one is this an illustration of?, is a question hanging. Another question hanging is, what artist's illustration is this? Similarly and also, when going on and defining each of the lettered layers in subsections of the article, it is not clear which lettering system that these lettered layers are part of. I gather that there is not a universal, natural, fundamental lettering system, so any one is somewhat arbitrary. It seems then that picking one and explaining upfront and/or in section titles that this is an explanation using the USDA terminology (if that is the one you have chosen) would be helpful to the reader. You could have a further section or footnotes explaining what are the principal differences in the Australian system. Just a suggestion... doncram ( talk) 22:51, 5 February 2008 (UTC)
I was reading a textbook for a class, and I came to this Wikipedia article to find out more information. As it turns out it was the same information, much of it word for word. I put the copyright violation template in the Diagnostic Surface Horizons section. I have not evaluated the content of the rest of the article. Falconus p t c 21:28, 14 September 2017 (UTC)

I'm not even remotely a soil expert, but I'm currently researching soil horizons for a class and I came across the Soil Survey Manual, as well as the Field Book from here. I found a notable difference between the two, and that is the SSM contains a "V horizon" while the Field Book does not. Chapter 3 of the SSM says that "V horizons are mineral horizons that formed at the soil surface or below a layer of rock fragments (e.g., desert pavement), a physical or biological crust, or recently deposited eolian material. They are characterized by the predominance of vesicular pores and have platy, prismatic, or columnar structure." Some more reading on this V horizon, or vesicular horizon, [3], showed me that it is a relatively new addition. It also seems to be of some importance. The Soil Science Society of America says that "It is important to study these soils because semi-arid lands cover about one third of the planet’s land area. Soils with vesicular horizons are often disturbed because populations of cities in arid environments are growing. There is construction of solar and wind farms, and these areas are popular for military exercises."
I think it would be a good idea to switch out the Field Book for Describing and Sampling Soils with the Soil Survey Manual for this reason. I would just go ahead and add the V horizon, but that would require me to change the entire source and potentially add/remove some stuff such as about the suffixes, which seems like a really major change for something I know little about, so I want to check here to see what anyone who knows more about soil than me thinks before I go ahead and make the change.

What is horizon B 2401:4900:3E27:2DEF:BF13:E638:9DD8:EA5D ( talk) 00:27, 24 September 2022 (UTC)
Define the term soil horizon and cite the defination 43.245.57.71 ( talk) 02:00, 20 April 2024 (UTC)
Hey, I'm 12 yr old Brazilian and there is some documentation about Horizon B (Search "MANEJO DE SOLOS – 6340" in Google and you'll find it). My science teacher also said things about it (he's a little crazy tho lol). Thank you :D 189.6.249.230 ( talk) 23:51, 21 April 2024 (UTC)
