The soil water with its constituents is called soil solution. A good vineyard soil is characterised by a good water retention capacity and optimal water drainage (without waterlogging). In most European wine-growing regions, the water supply is left to nature, as artificial irrigation is generally prohibited for quality wines and is subject to authorisation in exceptional cases.
