wet stress

See below irrigation,

The supply of water in the right quantity and at the best possible time is an important prerequisite for the growth of the vines and indispensable for photosynthesis. This is done naturally by precipitation (rain), the required amount is usually between 500 and 750 millimetres per year (depending on the climate). With ideal soil conditions, however, larger amounts of precipitation can also be tolerated. In the Portuguese Vinho Verde area, for example, the amount of precipitation is 1,500 millimetres. In addition to the amount, the time during the vegetation cycle also plays an important role.

The "right" amount of water is important, too little moisture can lead to water stress (also called drought stress), and excessive rainfall in turn leads to excessive vegetation (foliage growth). Especially during the grape harvest rain is undesirable and leads to poor wine quality due to the dilution of grape juice. In extreme cases, the so-called wetness stress occurs, in which the berries swell or even burst open and as a result the grape juice can oxidise or, in extreme cases, already ferment. In addition, too much moisture promotes infestation by certain microorganisms such as fungi or bacteria. In order to take any necessary measures, the soil moisture is measured by the Tensiometer.

Soil properties

Decisive for a good water balance is the type of soil, which is ideally loose and deep, so that the roots can spread out far or dig deep into the soil and thus easily absorb nutrients and water. It is important to have a good balance between...
