My soil is 7.5 to 8 pH in places. If I add dolomite lime to neutralize it, how long should I expect it to take to come down?
Lime raises the pH of soilIf you want to bring it down you need to add some form of sulfuralso adding organic matter would helpmaybe a top dressing of peat/sand or even better would be sieved garden compost mixed with sandIf your soil is very loose and sandy then I'd use mostly compost/peat or some sulfur
