“…As far as we know, there are no published data analyzing samples of whole vine leaves taken at harvest. Even so, recorded leaf nutrient concentrations are of the same order of magnitude as those found in the literature for blades of the leaves opposite to the cluster and taken at veraison (Davenport et al, 2012;García-Escudero et al, 2013). Previous studies have shown that grapes are the major sink for K after berry growth commences (Mpelasoka et al, 2003;Poni et al, 2003;Mullins et al, 2007).…”

“…However, the petiole nutrient concentrations at veraison here reported were not greatly dissimilar to those found in the literature (Mills and Jones, 1996;Fallahi et al, 2005;Davenport et al, 2012;García-Escudero et al, 2013), which suggested that the nutritional status of the vineyard used in this study is within the adequate range for the nutrients considered.…”

“…In spite of the effort that has been made in the standardization of the process of sampling, studies have shown that nutrient concentrations in plant tissues frequently fall outside the ranges currently considered normal or adequate in published standards (Winkler et al, 1974;Davenport et al, 2012). The great variability in plant analysis results has led to the establishment of standards for local growing conditions (Porro et al, 2001;Davenport et al, 2012;García-Escudero et al, 2013), important commercial cultivars (Fallahi et al, 2005;García-Escudero et al, 2013), or even rootstock-scion combinations (Lehoczky and Kocsis, 1998). However, the major limitation of plant analysis technology is its inability to provide quantified rates of nutrients to be applied.…”

a b s t r a c tPlant analysis plays a major role in fertilizer recommendations for perennial tree crops and vines. Plant analysis, however, does not quantify the rate of nutrients to apply. The approach developed in this work takes into account the content of the nutrients in grapevine parts and their dynamic within the plant to assist in the estimation of the amount of fertilizer to apply. Groups of three vines were cut at ground level on four different dates from September 14th to November 28th. On the first sampling date the vines were separated into trunk, cordons, canes, leaves and clusters for determination of dry matter content and elemental composition. On the following dates the vines were separated into the plant parts that were still present, since the clusters were only present on the first sampling date and the leaves on the first two. To assess the mobility of nutrients within the plant, samples of phloem vessels and sawdust of the entire trunk were taken as well as samples of chlorotic and green leaves. Nitrogen (N), potassium (K), phosphorus (P) and boron (B) showed mobility within the plant whereas calcium (Ca) and magnesium (Mg) did not. The removal of nutrients in clusters is critical for estimating N and K fertilizer rates. Clusters removed 19.9 kg N ha −1 and 28.7 kg K ha −1 . In the case of N, it is also important to assess the system's ability to recycle the nutrient contained in the leaves and canes which amounted to 49.4 kg N ha −1 . Phosphorus, calcium and magnesium applications might not justify being taken into account in the annual fertilization plan. Thus, the establishment of the fertilization programme should be a nutrient-specific exercise which takes into account all sources of information, including target yield and nutrient content in clusters, the vineyard management strategies influencing nutrient use efficiency from fallen leaves and prunings and soil testing and plant analysis.

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.

“…For each treatment, a total of 60 healthy leaves – 20 per repetition (only one leaf with petiole per vine, distributed randomly) – were collected to determine the grapevine nitrogen status. At bloom (mid‐June), leaves were sampled from nodes opposite to the first bunch, and at veraison (mid‐August) from nodes opposite to the second bunch . The petioles were detached from the blades and both were washed with tap water, rinsed with distilled water, and dried at 60 °C in a forced‐air oven (Selecta DryBig, JP Selecta, Barcelona, Spain) for 72 h. The dried material was ground and sieved to 0.5 mm in an ultracentrifugal mill (Retsch ZM1, Haan, Germany).…”
