Water extraction

Water extraction is one aspect of the complex process of water balance in plants. Other components are water storage capacity and water stress (see details there).

Bodenwasserkreislauf - Graphik

Soil water cycle: 1 = Precipitation, 2 = evaporation, 3 = water runoff, 4 = vegetation, 5 = soil, 6 = Adhesive water, 7 = seepage water & settling water, 8 = Groundwater & backwater, 9 = impermeable layer, 10 = capillary rise, 11 = infiltration, 12 = unsaturated transport, 13 = saturated transport

Prerequisites

Water is essential for photosynthesis and the supply of nutrients to the vine. For effective utilisation, it must be drained off quickly by running off or seeping into the soil. If necessary, this must be ensured by artificially created measures. This is supported by a cover crop or an organic mulch cover. In extreme cases, an artificial drainage system must be installed at great expense. The vineyards of the Médoc were only transformed from a "swampland" into today's world-famous wine-growing region in the 17th century through elaborate drainage and drainage measures.

There is a vast number of sources on the web where one can acquire knowledge about wine. But none has the scope, timeliness and accuracy of the information in the encyclopaedia at wein.plus. I use it regularly and rely on it.
