Year 1 TrialYear 1 Trial
• Capiphon can be used to irrigate vineyards. • Only low head required < 30cm• Level of rise can be controlled by raising/lowering head• Wetting band 1-2 metres either side• Flow rate less than standard drippers.• Flow rate varies according to existing soil moisture.

Equivalent fruit yield
The Treatment effect is highly statistically significant, showing no evidence of a difference in Fruit weight between the Capiphon and Drip treatments, but a sizable reduction of 1.73 units (95% Confidence interval 0.80 - 2.66) between the nil and Capiphon treatments.

Conclusions
Capiphon Irrigation • Delivered water to plant root zone in a vineyard• Used less water• No significant difference in fruit yield compared to Drip
![Page 33: What is Capiphon? Revolutionary Drainage Technology Best Invention of the Year 1999 International Exhibition on Ideas, Inventions and Novelties Nuremberg](https://reader036.vdocuments.pub/reader036/viewer/2022062620/551affd655034607418b4952/html5/thumbnails/33.jpg)
Further Work
• Larger, more refined trials• Trials with less water• Other crops• Differing soil profiles• Differing slopes• Root spread • Infrastructure• Optimal operational procedures• Lots, lots more …
