Context and purpose of the study ‐ Ground water in the interior valleys of California is contaminated with nitrates derived from agricultural activities, primarily the over fertilization of crops. Agriculture is now mandated by the State of California to monitor all possible nitrogen (N) inputs into agro‐ecosystems and only apply N amounts that meet a crop’s […]
Read MoreContext and purpose of the study ‐ Protecting table grape vineyards with white hail‐nets is a common practice in Southern Italy. Hail‐nets result in shading effects of 10‐20 %, depending on their density and type of weave, thus they act as a low shading nets and modify the vineyard microclimate. Darker nets are more opaque […]
Read MoreContext and purpose of the study ‐ Nutrients in municipal treated wastewater (N, P, K, mainly) are a particular advantage in this source over conventional irrigation water sources, so supplemental fertilizers would sometimes not be necessary. However, additional environmental and health requirements are taken into account for this source of irrigation water. Most treated wastewaters […]
Read MoreContext and purpose of the study ‐ Irrigation management is a critical aspect in grapevine cultivation to regularize grape production and quality in areas of clear water limitation. The scarcity of information implies the need to know the plant water status to make an estimate of the response of cv. Verdejo to the variation of […]
Read MoreContext and purpose of the study – Priorat and Montsant Appellations of Origin are located in the south of Catalonia (North‐East Spain), under severe Mediterranean climatic conditions, in terms of rainfall and water availability. Taking both appellations together, they account for close to 4000 ha cultivated by more than 1300 vine growers. Due to water […]
Read MoreContext and purpose of the study ‐ Knowledge of vine reaction to plant spacing under high potential soil conditions is restricted. This study was done to determine effects of vine spacing (with fixed row spacing) of Shiraz/101‐14 Mgt on a high potential soil on vine physiological reaction, growth, yield and grape composition. The study is targeting […]
Read MoreContext and purpose of the study ‐ In previous experiments carried out in Bologna on Sangiovese grapevines raised with the Australian “Minimal Pruning” system, it has been shown that this system left an excessive burden of buds on the vine (650/meter of row) and inhibited the plant from correctly activating its physiologic self‐regulating mechanisms, thus […]
Read MoreContext and purpose of the study – Vine development, and hence management, depends on dynamic factors (climate, soil moisture, cultural practices etc.) whose impact can vary depending upon their temporal modalities (timing, duration, threshold, eventually trajectory and memory effects). Therefore, understanding the effect of the temporal variation of these factors on grapevine physiology would be […]
Context and purpose of the study ‐ Phytopathogenic diseases impact the development and yield of grapevines, resulting in economical, social and environmental losses. Sick plants have their metabolism changed, leading to alterations in their reflectance spectra. Little is known on these alterations, and a better knowledge could be used in the development of sensors able […]
Context and purpose of the study ‐ Random sampling is often considered to be the best protocol for fruit sampling because it is assumed to produce a sample that best represents the vineyard population. However, the time and effort in collecting and processing large random samples can be cost prohibitive. When information about known field […]
