Einflusses auf qualitäts- und verarbeitungsbezogene Faktoren der Ernteprodukte
eine kontinuierliche Beachtung und Überprüfung. Eine Herausforderung stellt die
Identifizierung und Anwendung optimaler N-Versorgungsstufen dar, da es enge
Wechselwirkungen mit Umweltfaktoren, weiteren zugeführten Nährstoffen und dem
jeweiligen Sortenpotential gibt. Da Stickstoff hinsichtlich der Qualitätsbildung sowohl
positive Wirkungen (Proteinbildung) als auch nachteilige Wirkungen entfalten kann
(Akkumulation von Nitrat, Beeinträchtigung von Syntheseprozessen), werden diese
Erwägungen bei Entscheidungen über die Höhe der N-Zufuhr zunehmend
berücksichtigt.
