So, : "In version 1.19.0-rc.1, High Fertility Soil was changed to occur naturally in the world, and Terra Preta can only be crafted.[4] The recipe for Terra Preta in 1.19 is more expensive than the recipe for High Fertility Soil was in 1.18." but "Potash's only use as of version 1.20.12 is as with a 60% K value. The first time potash is used as a fertilizer on a block of farmland, its maximum K fertility will be increased by 15%. When this occurs, other nutrient levels are unaffected, but the farmland will visually change to the next highest quality farmland (Barren -> Low fertility -> Medium fertility -> High fertility -> Terra preta). The problem is that it changes block name too so you can have various types on terra pretta in the garden and no way to tell with one is real with one is fake. So if you try to boost fake one it will not max levels. I think fake potash soils should have different names, like potash terra pretta or soemthing.
