“…In 2016, YAN values were higher in TC than in FH samples, but the same in PP samples, while in 2017 they were highest in FH, followed by TC, and lowest in PP samples (Table ). These results were in agreement with the observation that the vine nitrogen status was highly correlated with the ammonia and must nitrogen status and with the soil N‐NO 3 − content …”

“…46 However, our soils had a low organic matter content [FH, 1.1; TC, 0.9 and PP, 1,1% (w/w)], which is in accordance with the low soil nitrogen content observed. The N-NO 3 − values observed in our soils were similar to those reported by Smith et al 47 and Steenwerth and Belina 48 in vineyards with Mediterranean conditions and by Peregrina et al 49 and Pérez-Álvarez et al 50,51 in soils of the same wine-growing region. Despite this low nitrogen content, the grapevines of the three vineyards studied here are able to reach the production limit (6500 kg ha −1 ) that conforms with the A.O.C.…”

BACKGROUND Soil and climate are among the most determining factors for the composition of grapes. Among the compounds present in grapes, anthocyanins mainly determine their organoleptic and health‐related properties. The purpose of this work was to study the influence of three different soils on the anthocyanin content of Tempranillo grapes (Vitis vinifera L.) from 2016 and 2017 vintages. The soils of the vineyards were classified as Fluventic Haploxerepts (FH), Typic Calcixerepts (TC) and Petrocalcic Palexerolls (PP). RESULTS Non‐acylated anthocyanins, and those derived from malvidin and peonidin, were the most abundant in grapes, regardless of soil type and year. During the wetter season (2016), the grapes with the highest concentration of total anthocyanins and several of the major anthocyanins were those from TC and PP soils, in which nitrogen availability was lower than that in FH soil. However, during the drier season (2017), no significant differences were observed, although trends similar to those seen in the 2016 season were recognized. Principal component analysis showed a good separation of samples according to the two seasons and to the three soils in each season. CONCLUSION In vineyards that resemble each other closely and that are located in a unique mesoclimatic area where similar plant material is used and similar managements practices are applied, soil characteristics, which condition water holding capacity and nitrogen availability for the vines, in conjunction with seasonal conditions, were the factors that predominantly determined the anthocyanin composition in grapes. © 2019 Society of Chemical Industry

“…Table shows the soil nitrogen content, N‐NH 4 + and N‐NO 3 − at the different depths in 2014 and 2015, at bloom. Nitrogen levels were low, as observed previously in soils from the same vineyard area, although soil N‐NO 3 − levels were similar to those reported by Smith et al and Steenwerth and Belina for vineyards in Mediterranean conditions. The medium organic‐matter content and the presence of a petrocalcic horizon, which have physical constraints with respect to depth of root growth (Table ), in addition to the semi‐arid conditions in the area, might explain why the experimental plot present reduced soil nitrogen levels.…”

“…This result agrees with the relationship between soil NO 3 − -N availability at bloom and leaf N content found in cv. Tempranillo vineyards in the AOC Rioja (Pérez-Álvarez et al 2013b). Moreover, in the third year with B cover crop, N concentration in both blade and petiole tissues and at both bloom and veraison stages reached deficient values according to reference levels for cv.…”

Aim The aim was to study the effects of two different cover crops (leguminous versus gramineous) on soil NO 3 − -N availability, grapevine N status, and yeastassimilable N (YAN) and amino acid profile in the must of a cv. Tempranillo vineyard from La Rioja (Spain) over 3 years.Methods Three treatments were established: gramineous (barley) and leguminous (Persian clover) cover crops and conventional tillage. Soil total N and extractable NH 4 + -N at bloom, soil NO 3 − -N content from budbreak to postharvest, leaf N content at bloom, and free amino acids and ammonia in must were monitored.Results Each year, the barley cover crop treatment had lower soil NO 3 − -N than tillage, while the clover treatment showed lower soil NO 3 − -N than tillage in 2009 and showed higher values in 2010 and 2011. In 2011 leaf N content, yeastassimilable N (YAN), and some amino acids in the grapes were lower in barley cover crop treatment thus affecting the amino acid profile. Meanwhile, the clover cover crop did not have these effects. Furthermore, relationships between leaf N content and various amino acids were also found.Conclusions With the barley cover crop treatment, soil N availability decreased from the first year of the experiment, provoking a decrease in N grapevine status and in content of YAN and various amino acids at the third year. In contrast, clover cover crop maintained N grapevine status, YAN, and amino acid profile similar to conventional tillage. Therefore, our study shows how soil N can be managed both within a year and from year to year when two different cover crops are sown and how the grapevine N nutritional status and YAN content and amino acid profile can be modified in the must.
