Nutrient Availability in the Soil and Its Absorption, Transport, and Redistribution in Vines

Qualitative Assessment of the White Wine Varieties Grown in Dealu Bujorului Vineyard, Romania

“…Europe has the highest percentage 51% of the global surface cultivated with vines, followed by Asia, America, and Africa (Gonçalves da Silva et al, 2008). The wine-growing area in Romania has decreased since the 1990s, currently it ranks fifth in Europe after Spain, Italy, France and Portugal, so that in 2013 Romania had an area of 229 000 hectares planted with vines (Bora et al, 2015).…”

<p>Nutrient Balance and Fertilizer Use Efficiency in Swedish Vineyards</p>

“…However, the nutrient levels in vine biomass fractions can be expected to vary considerably depending on the phenological stage and variety of grapes grown. 5 Studies in Brazil by 6 showed that the N content of leaves and branches dropped by 19% and 23%, respectively, from flowering to maturity, while the P content decreased by 74% in the leaves and 41% in the branches, and the K content declined by 21% and 56%, respectively. Another study analyzing the nutrient content of different plant parts of pinot noir grapes in Oregon, USA, found that the N content of stems, petioles, leaves, and grapes varied between 4 and 37 g per kg DM during the growing season, with higher values in the beginning of the season and then a decline.…”

Research on artificial neural networks to accurately predict element concentrations in nutrient solutions

“…So the sample design considered the dilution of the nutrient solution. Moreover, there are differences in the amount of elements absorbed by plants, and there are also species and individual differences among different plants [22,23]. The growth environment and stage also affect the absorption of elemental ions by plants [24,25].…”
