Steel,Red oak is tolerant of acidic soils.I can show you dozens of exclosures that were never treated and have have excellent oak regeneration.The only thing they're missing is large deer herds.I can also show you areas that were limed and you'll see no difference between the treated and un-treated areas with the exception of bracken ferns.Bracken ferns seem to take a liking to lime.

Acidic soils shave had a very pronouned effect on hard maple,not oak regeneration.The soils in oak forests are very acidic by nature,regardless of rainfall
