Water supply

See under water balance.

In the geosciences, the term water balance (hydrology) is used to describe the absorption and release of water in a larger geographical area, such as an ocean or a landscape. In the case of landscapes, surface water, evaporation, climate, precipitation and groundwater flows are taken into account. The water balance largely determines the ecosystems and the type of vegetation that can establish themselves in the landscape and the suitability for agricultural use.

In the context of a vineyard, the water balance refers to the complex interaction between the uptake and release of water in the vines and the surrounding soil type. Similar to larger landscapes, several factors play a role, including surface water from rainfall or artificial irrigation , the evaporation of water through the leaves of the vines, the microclimate of the vineyard, rainfall patterns and the movement of groundwater. These factors influence the water retention capacity of the soil and water drainage , which has a direct impact on the growth and development of the vines.

Serious sources on the internet are rare - and Wine lexicon from wein.plus is one such source. When researching for my articles, I regularly consult the wein.plus encyclopaedia. There I get reliable and detailed information.
