What is the soil water preference of oak trees?

Slightly acidic is the soil water preference of oak trees (Quercus spp).

Specifically, the American chestnut (Castanea dentata), oak and pine (Strobus spp) rank among the trees that historically prefer more acidic soils and soil water. Additionally, the three trees tend to be the historic contributors to acidifying trends in area soils and water bodies. They also will be found in close quarters with acid-loving, delicious berry-sporting shrubs.
