Tea leaves and soils from 13 tea gardens in the People's Republic of China were assayed for aluminum concentration. The Al levels in leaves were best predicted by available Al extracted by 0.02 M calcium chloride, and the Al concentration in leaves increased with declines in soil pH. The amount of Al in soils extracted with calcium chloride was lower than that for other forms of Al in soils. The amount of Al detected in leaves was directly related to both the available form of Al in soils and soil pH.
