“…Deficit irrigation strategies (e.g., regulated deficit irrigation -RDI; partial root drying -PRD; sustained deficit irrigation -SDI) can be used to improve WUE, allowing an optimal grape maturity and wine quality. Different deficit irrigation techniques are usually achieved by assessing soil (water potential and moisture) and physiological parameters (leaf or stem water potential, relative transpiration using sap flow techniques, trunk growth variations, canopy temperature, and chlorophyll fluorescence) as water status indicators (Pellegrino et al 2004;Cifre et al 2005;Sousa et al 2006;Centeno et al 2010). Romero et al (2010), using RDI by applying 60% crop evapotranspiration (ETc.)…”

The importance of viticulture and of the winemaking socioeconomic sector in Europe is largely acknowledged. The most famous winemaking regions in Europe commonly present very specific environmental characteristics, where climate often plays a central role. Furthermore, given the strong influence of the atmospheric factors on this crop, climate change can significantly affect yield and wine quality under future conditions. Trends recorded in the recent past on many viticultural regions in Europe hint at an already pronounced increase in the growing‐season mean temperatures. Furthermore, climate‐change projections give evidence for significant changes in both the growing‐season temperatures and precipitations in the next decades. Although grapevines have several survival strategies, the mounting evidence for significant climate change in the upcoming decades urges adaptation and mitigation measures to be taken by the whole winemaking sector. Short‐term adaptation measures can be considered as a first protection strategy and should be focused at specific threats, mostly changes in crop‐management practices (e.g., irrigation, sunscreens for leaf protection). At long term, however, a wide range of adaptation measures should be considered (e.g., varietal and land allocation changes). An overview of the current scientific knowledge, mostly concerning the European viticulture, the potential climate change impacts, and feasible adaptation measures is provided herein.

“…Under increased drought stress conditions, stomatal conductivity is both impacted by the vapour pressure deficit and the soil water potential (Centeno, Baeza, & Lissarrague, 2010). Plots show different developments of drought stress during the season.…”

Thermometry and thermography are alternative methods used for measuring stomatal conductivity via transpirative cooling. However, the influence of mixed soil–plant information contained in thermal images compared to thermometric spot measurements on the measurement quality and relationships to agronomic traits remains unclear. To evaluate their respective influence, canopy temperature was measured simultaneously by two infrared thermometers (thermometry), which were oriented oblique to the plant canopy and mounted on a tractor, and a hand‐held, nadir oriented thermal camera (thermography) in irrigated and drought‐stressed spring barley cultivar trials in 2011. Canopy temperatures were separated from soil temperatures and extracted from the thermal images by matching thermal and RGB images. Thermometric measurements conducted at the beginning of shooting during a stable period of high radiation were more closely related to total plant biomass and straw yield at harvest than thermography under both irrigated and drought‐stressed conditions. Taking into account the results of this evaluation, thermometry was used for assessing the agronomic importance of stomatal sensitivity, the earliness of stomatal closure, of spring barley cultivars subjected to different water supply in 2013. In this year, 16 spring barley cultivars were grown under mild drought stress and rainfed conditions. A stomatal sensitivity index was derived relating canopy temperatures of the cultivars grown under rainfed and drought‐stressed conditions to each other. Under rainfed conditions, stomatal sensitivity was negatively related to grain protein yield with a coefficient of determination of R2 = .43. Under increasing terminal drought stress, positive regression slopes of stomatal sensitivity to grain yield, biomass yield and culms/m2 were observed with coefficients of determination amounting to R2 = .22, .31 and .36, respectively. Stomatal sensitivity negatively impacts agricultural production under well‐watered conditions, but maintains productivity under conditions of terminal drought.

“…The electrical resistance of the matrix material, which is in equilibrium with that of the surrounding soil, is measured and then used to estimate the SWP value through a suitable calibration function. Due to its low cost, the Watermark sensor can be included in the range of products that can be used both for research and for practical applications (Loiskandl et al, 1999;Shock and Feibert, 2002;Thompson et al, 2006Thompson et al, , 2007bCenteno et al, 2010), although its accuracy is not comparable to the more sophisticated soil moisture sensors based on time domain or frequency domain reflectometry technologies (Terzis et al, 2010). The sensor has an average lifetime of about 5 years and once placed in the soil it does not require specific maintenance.…”

“…The sensor has an average lifetime of about 5 years and once placed in the soil it does not require specific maintenance. The sensor can provide estimates of SWP over a wide range of tensions, namely from approximately 0 to À240 kPa (Centeno et al, 2010). It operates at low voltages (5 V), but requires alternating current excitation (AC) rather than direct to avoid polarization of the metallic components (Fisher and Gould, 2012).…”

Irrig-OH: An Open-Hardware Device for Soil Water Potential Monitoring and Irrigation Management

Sustainability of irrigation practices is an important objective to be pursued in many countries, especially in regions where water scarcity causes strong conflicts among different water uses. The efficient use of irrigation water is a key factor in coping with the food demands of an increasing world population and with the negative effects of climate change on water resource availability in many areas. In this complex context, it is important that farmers can rely on instruments and practices that enable a better management of water at the field scale, whatever the irrigation method they adopt. In this paper, we present an open‐hardware device based on the Arduino technology that was developed to allow the continuous monitoring of soil water potential in the root zone for supporting irrigation scheduling at the field scale. The structure of the device is flexible and can be adapted to host different types of sensors. The results, obtained managing irrigation in a peach orchard, show that adoption of the device, together with a simple irrigation scheduling criterion, allowed a significant increase of water use efficiency without causing a reduction of the quantity and quality of crop production.
