  • Pretty sure there are crops you can rotate in that replenish the soil.

    Potassium is produced by breaking down potassium-rich rocks. Plants cannot replenish it like they replenish nitrogen.

    There’s also a literal shitload of organic waste that humans generate that can be used for a similar purpose instead of burying it in landfills.

    We do produce a lot of potassium-rich waste - sewage and food waste, for example - but most of it is also rich in other nutrients. So you can add a little of it, but adding too much of it can cause other problems (like eutrophication).

    The other solution is to buy potassium fertiliser. A significant amount of this is produced in Russia, Kazakhstan and Ukraine, and I’m guessing its trade is being affected by the ongoing war.
