I'm in the 7.4-7.6 range depending on time of day. I guess I still need to do more research. The chemical applicators and farmers here don't use lime in the NW (very NW) corner of Kansas, go in the other direction normally. I can't even find lime within 200 miles of here. Locals keep telling me no on Lime and use soda ash.. I need to find out why Lime in particular, is recommended over Sodium Carb.. is it based on water PH only?? What I find in research shows in becomes active with the bottom compounds as well. Don't know how credible it is but KU study shows a graph that says PH above 7.2, Not to add any Lime. Apparently I'm just not finding the right data to tell me why 1 over the other. Not trying to be difficult here, I just need to understand.
