Poor growth of vines after multiple use of a soil, especially when used as a vine nursery. Depending on the type of soil, this manifests itself as a decline in vegetative and generative performance with poor growth with short shoots and death of roots. The causes are manifold and partly only incompletely known. Among other things, these include an enrichment of the soil with certain bacteria and damaging root excretions. Prevention can be achieved by frequent changes of the vineyard school areas. A reduction of the negative effects is possible by adding mycorrhiza (fungal species) or carbon disulphide. Vine fatigue can be largely eliminated by targeted soil remediation measures and subsequent replanting. See also under vine enemies.
For me, Lexicon from wein.plus is the most comprehensive and best source of information about wine currently available.
