Sensitivity of Grapevine Soil–Water Balance to Rainfall Spatial Variability at Local Scale Level
Frontiers in Environmental Science, 2020 In rainfed agriculture systems, rainfall water management (harvesting, storage, and efficient use) is a key issue. At local scale (i.e., from 100 m to 50 km), the impact of rainfall spatial and temporal variability on crop water availability is seldom ...

Soils and water uptake by vines in pomerol (france). I - Soils distribution and variability
OENO One, 1997 The Pomerol vineyard (France) is located 35 km east from Bordeaux, on the left side of the Isle river. Its area is approximately 800 ha. The geology is made of a system of fluvial terraces, including gravels and stones of various sizes.

Utilization of unmanned aerial vehicles for zonal winemaking in cool-climate Riesling vineyards
OENO One, 2022 Individual vineyards can vary spatially for several viticultural attributes, including water stress, nutrient status, growth/vigour and disease—which can, in turn, impact berry composition and resulting wine products.

Grapevine vigour and within vineyard variability: a review
, 2016 [EN] Vine vigour involves the production capacity of the vine. Production capacity encompasses shoot and leaf production, as well as grape production. It would benefit grape production systems to find the correct balance between the vegetative growth (shoot and leaf ¿production¿) and reproductive development (grape production).

The role of venture‐financed startups in innovation for US agriculture
American Journal of Agricultural Economics, EarlyView.Abstract To evaluate the role played by startup companies in the innovation ecosystem of US agriculture, we compile a unique dataset of 6024 new entrants founded 1987–2019 that details their financing lifecycles, annual economic performance, and patenting activities.

Remote Sensing of Soil Moisture in Vineyards Using Airborne and Ground-Based Thermal Inertia Data
Remote Sensing, 2013 Thermal remote sensing of soil moisture in vineyards is a challenge. The grass-covered soil, in addition to a standing grape canopy, create complex patterns of heating and cooling and increase the surface temperature variability between vine rows.

Comparing vineyard imagery acquired from Sentinel-2 and Unmanned Aerial Vehicle (UAV) platform
OENO One, 2020 Aim: The recent availability of Sentinel-2 satellites has led to an increasing interest in their use in viticulture. The aim of this short communication is to determine performance and limitation of a Sentinel-2 vegetation index in precision viticulture ...
