  • The dust bowl stretched as far north as Palliser’s triangle.

    I’ve dug pits near Selkirk MB, and average topsoil depth in that area is 20 cm, and the soils are regosolic (meaning it’s topsoil over top of regolith, rather than having a transitional horizon) in most farmers fields.

    Go off into the bush 200 m away, and the soil there, that had the exact same pedogenic conditions has the 60 cm of Ah horizon (black topsoil), super strong structure, a fully developed B horizon (that transition horizon I mentioned earlier) and then the C (regolith).

    This is all because the area lost a foot of topsoil during the 30s, and what was left was poorly managed - conventional tillage for decades - which has caused plow erosion of the B horizon and admixing of the poorer subsoil horizons into the A horizon.

    This erosion of the B happens because in a conventional tillage system, you lose a few mm of soil each year off the top, yet your plow depth settings don’t change because you still need that 30 cm or whatever it is to grow your crops.





  • I disagree with you, and @relianceschool@slrpnk.net - respectfully.

    I’m not trying to detract from AI’s issues, or insist that we can only address one issue at a time. However, if I was given $100 Million to address these issues, I’d be investing 99 millon into dealing with water, land, and mining related issues, as those can have immediate effects. Emissions are such a hard one to address, since it requires buy in from literally everyone (look how hard that was with COVID, and people were dying right there and then due to it). Regulating and reducing AI emissions seems a lower priorty to me compared to things like better O&G regulation which are likely to have larger impacts on overall emssions.




  • Unrelated, but those Russian peat samplers they show in the picture SUCK ASS to work with.

    You punch them into the peat using your body weight. You turn it exactly 180 degrees, then you pull it up, fighting the whole time with grip and peat suction. If you turn 179 degrees or 181 degrees, you miss the slot for the fin that you created on the way down and now have to pull 10x harder.

    It only takes 50 cm bites, and you need 50 cm increments to describe the peat profile. The deepest peat I dug was 780 cm.

    If you push it into the underlying mineral soil, it gets stuck, and you need 2 or more people to help pull. We once devised a system of ratchet straps to help pull it up and that barely worked.

    Oh and the sampler and it’s extensions are heavy as fuck, and the threads jam up. Now carry this god forsaken torture device though kilometers of spongey peat hummocks…

    Fucking preach. You’re very right, and my stance aligns closely with yours. Another thing I read while doing my degree was that the C-O-alkyl groups were inductive of the stability of BC and availability for mineralization.

    Again, BC is good as a C storage source and might even have some soil boosting effects but those effects were secondary. A lot of the benefits generally come from increased porosity/critter habitat.

    It’s also fucking expensive to make without generating a shit ton of CO2 in the process so it’s a crap amendment in general

    I just thought the worm was cute.
