To that water as an essential remedy for the photosynthesis and supply with nutrients of vine To be able to use effectively, a rapid withdrawal must be made by draining or seeping into the vineyard soil. If necessary, this must be ensured by artificially created measures. This is supported for example by a greening or by an organic mulch, In extreme cases, an artificial drainage must be created with a correspondingly high outlay. The vineyards of Médoc Incidentally, in the 17th century, extensive and complex drainage and drainage measures only became part of the "swamp landscape" of today's world-famous wine-growing region.

Of course, a certain amount of water for the supply of the plants must be obtained or bound from the ground and therefore ever soil type very different . If the seepage of excess water is prevented by a water-impermeable layer, it can lead to waterlogging. Longer lasting, this is from the expulsion Extremely harmful in the spring, because it limits root growth and reduces the activity of the plant microorganisms is restricted in the ground. This leads to a lack of nutrients. Wetness in the soil at the time of blossom leads to bad fruit set and Verrieseln,

Waterlogging is extremely negative, especially in the bottom main layer, which is permeated by the majority of the roots. In the underlying subsoil, waterlogging is acceptable to some extent, but it reduces the depth of the root with all the possible negative effects. Such a subfloor usually has a characteristic bleached, whitish gray color. A good drainage usually have loose and stony soil types with deposits of lime, gravel and chalk. In contrast, dense, heavy soils of clay, clay and sand tend to waterlogging or to a poor water extraction.

A high content potassium gives the soil a permeable crumbiness with good water extraction, sometimes even on heavy soils. For soils with unacceptable poor drainage, the choice is appropriate document very important.
