Indigenous land conservation practices such as seasonal grazing and shifting cultivation recognised this vulnerability by allowing the vegetation and soil to recover. However, these were gradually eroded by colonial and postcolonial governance, which prioritised formal land tenure and permanent settlement but paid little attention to soil productivity and protection from erosion.

Ultimately, erosion control cannot be treated as a solely environmental problem.

Happy for you...

I recently took a job where I take soil flux samples on a regular basis. We're monitoring CO2 for the most part with a licor 850, but sometimes CH4 too with a licor 7810 iirc.

I don't really know what I'm doing. I'm going through the motions but I don't fully trust the data that's coming out. It looks right, but we have a custom built setup and can't use soil collars or the fancy fully automated licor domes. I tried performing a DIY leak test today and left more confused than when I started. Can anyone point me to some resources on proper sampling technique and equipment maintainance, or perhaps a proper way to perform a leak test, if any?

Thanks

This profile has ice wedges that melted you can see them in this second picture. Textures are sandy loam over loamy sand, but the wedges are filled in with silt or finer

I thought this community might enjoy seeing the layers i found while digging a pond in my yard. Depth is about 2 feet.

In the Canadian system, this would be a Eluviated District Brunisol. Note the two E horizons - this is referred to as a bisequa soil, where the original profile is buried and then pedogenesis begins again and forms a mini profile over the buried one.

Canadian description would be:

Om Ae Bm IIAeb IIBm II C

Coarse fragments

Heating alone won’t drive soil microbes to release more carbon dioxide — they need added carbon and nutrients to thrive. This finding challenges assumptions about how climate warming influences soil emissions.
