So Im back with my head in the books as I always am every off-season and Im trying to wrap my head around what PH really means. To that end I'd like to bounce a couple of thoughts/questions off of the real experts here and see if Im in the ballpark or totally off the ranch. Here goes: Would if be accurate to say that instead of being a relative measure of acidity or alkalinity PH is ultimately a measurement of the relationships between relative amounts of Calcium, Magnesium, Potassium, and Phosphate present in the soil?? So in other words acidic or alkaline soils are symptoms rather than conditions?? If Im off base about this then there probably isn't much point in reading any further but..... If Im in the ballpark there (big IF) then is the paradigm of lime or gypsum applications really the best way to address PH issues?? Now keep in mind that Im totally self-taught here so don't worry about dumbing down your answers.
