Summary in the original language of the document
This practice abstract deliers benefits and practical recommendations concerning subsurface irrigation including 3 main steps of subsurface drip irrigation system installation on the plot. You will also learn about simplified cost/benefit analysis for subsurface irrigation and get various links with further information materials.

| Teaser: | Better water use efficiency, facilitating the establishment of vegetal cover in viticulture. |
| What problem does the tool address?: | Winegrowers are no longer able to perfectly control their production systems due to summer drought. Aerial drip irrigation under the vine row is the most widely used system, but is it the most efficient? The objective of this study was to examine the profiles of soil wet bulbs obtained from 2 irrigation systems: aerial drip located under the vine row and subsurface drip located in the middle of the vine inter-row. |
| What solution does the tool offer?: | In this experiment, using capacitive probes in the soil, it was demonstrated that subsurface irrigation (40 cm depth) in the middle of the row generated larger volumes of wet bulb, with vertical and lateral percolation of the water, than aerial drip irrigation system (Figure 1). Subsurface irrigation in the inter-row did not change the vines' water status or the yields compared to aerial irrigation under the vine row. During our trial, it was also possible to visualize, without measurement, that the water from the subsurface irrigation reached the ground surface by capillarity. This still underdeveloped irrigation system could be a lever in dry areas to promote the establishment of plant cover in the inter-row, which is known for providing a set of sustainable services. |
