Mineral weathering (MWe; see Glossary) is an important process by which nutrients are released from minerals and rocks.This process depends not only on the intrinsic parameters of the minerals (i.e., their physicochemical properties) [1], but also extrinsic ones (i.e., pH, water circulation, biotic activity).Mineral weathering has several essential roles in our environment.
