    Honestly, it makes more sense - what am I, a mid-level scientist, going to bring to that corporate atmosphere? You’re going to ask me to brainstorm in a meeting with an Executive VP? Yeah. Fucking. Right.

    You give me work, I do the work. Yes I might need to ask a question, but that’s uncommon and I can just teams for that.

    The seniors execs? That makes sense. They need to all be on the same page, and talking to each other. Collaborating etc.

    Honestly - the joker is more the stark raving lunatic rather than the cold blooded psychopath. He’s more liable to strap you into a rollercoaster, set it off, and have a cream pie (not that one) waiting for you at the end of it - the impact of which kills you - rather than blowing up boat full of people.







  • First and foremost, I’m not trying to nitpick - I just really like dirt. It’s embarrassing kinda.

    Secondly, being a good soil scientist doesn’t necessarily mean you have a good understanding of plant requirements. Plants are their own can of worms, and their needs vary by species.

    Third, the soil carbon and fertility cycle is a terrifying place. There are so many facets of organic matter in the soil it will make your head spin. In some cases OM can be physically protected by other, more recalcitrant OM.

    Building up OM can yield more humus and more cation exchange capacity, which does play a role in fertility for secondary and micronutrients.

    I really don’t know much about fungi holding onto minerals, but in general, the organic nutrients (like P tied up in ATP) only get released when organisms die, so in that capacity fungi and other biota play a buffering role


  • Yes, but again, it don’t think it’s evolutionary strategy, rather than the content of the needles is what is needed, and the acidification is just a knock on effect. Pines in particular are disturbance specialists - they take off after fire, and drop relatively few needles during establishment when competition from grasses and other plants is at the highest. When they get larger they don’t have to worry (,as it were) because you can choke out anything below you just by being big

    Point of clarification: organic matter doesn’t really retain the nutrients but acts as the slowly mineralized pool of nutrients associated with soil quality.

    The way you describe it is similar to how a sponge works rather than a storehouse.

    You are right, though, in that you don’t need to fertilize trees for the most part. Forest soils are hilariously low in nutrients: TOC is around 1% and N is next to non existent (N is highly labile), while P and K are moderate to high. As a result, forests veg is most competitive in nutrient poor conditions. If you fertilize a disturbed area, you get a pile of weeds and grass that can set back your revegetation timeline because your desirable woody spp now have to out-compete them. This process still happens if you don’t fertilize, but it’s generally less pronounced and allows some woody plants to gain the foothold they need
