but also the use of phosphate causes environmental problems. so why is phosphoric acid better then peat?

Never really thought about the lack of phosphate so far. So thank you for your remark and reminder!
And you are right: There will always be a downside. (That’s why I raised this topic. And that is why I try to use as much rainwater as possible (not too big a problem with our small paro tanks, at least if you have a garden some distance away from the city.), collect alder “cones”, beech and oak leaves etc. on every walk, hike or bike trip :)…)
