This is a work in progress, please don't mind the mess.
Subdisciplines of soil science include:
- Soil Taxonomy & mapping
- Soil Fertility & Organic Amendments
- Soil Chemistry & Remediation
- Soil Mineralogy

This is a really nice one. While I kind of wish the photo quality was better, I kind of like the way it is since it gives it a kind of painted impressionist look to it.
if you look closely, under the Ae (the white horizon) you can see a thin Bh horizon, where organic acids have leached from the Ae and been deposited. Below that is the Bf horizon, where iron from the Ae deposited.
this podzol looks like it's developed on till, given the look of the C horizon (clay loamish looking) and the shape of the rocks on the left hand side.
Great share! post more!
Yeah, this was from back in 2018 during the North American Forest Soil Conference, so it was taken with an old, crappy iPhone 5 camera. Still a good representation of the colors.
The other cool feature of this profile was the suspected krotovina(s). On the left, the light colored region looked like a burrow filled with light, E/Ae horizon material, while the patch on the right was filled with organic matter (it’s not just slough from the surface)
I didn't notice the Krotovina! Very cool!
Crazy how much better cameras are now though
