FRUITION
DUALEX^® Signature

Foliar Nitrogen
Photometric Sensor

Monitor fertilization needs based on plant response

In partnership
with Force A

HOW IT WORKS?

We scan leaves in the canopy over multiple dates during leaf area development

After each scan, we plot a new point showing your nitrogen uptake for the season

The graphs are automatically uploaded to Fruition’s online-platform to compare with weather data and other vineyard data

KEY FEATURES

Non destructive

Monitor block Nitrogen content at peak value

why is it useful?

For winemaking

Enhance wine color and flavor
Improve pre-harvest Yeast Assimilable Nitrogen

For viticulture

Improve timing for fertilization
Reduce fertilization based on plant needs
Select best block for organic/biodynamic farming
Monitor season and practice effects on Nitrogen

The Dualex readings provided by Fruition Sciences provide another level of Nitrogen update and utilization within the grapevine. Previously we, as an industry, relied on yearly or bi-yearly petiole reading for Nitrogen levels in our vines. Weekly readings provide deeper insight into the nature of the vine, especially during key physiological stages like flowering and veraison. Correlating this with development of anthocyanin in the berries and with the extraction and stabilization of anthocyanin during fermentation will continue to inform decision making...and most importantly allow us to grow better grapes and make better wine.
