In a similar way that water application can have a massive impact on vine growth, the application of nutrients, in terms of quantity, type and timing can heavily influence the outcome of a season. As grapes are harvested and the fruit and stalks removed from a vineyard, the nutrients that contributed to that plant matter are removed from the vineyard as well. Without replacement of these nutrients, the vineyard will end up in a nutrient deficit. It is advisable that as a minimum the nutrients removed are replaced, with consideration of the efficiency of application and possible losses.

Nutrients contribute to plant and fruit development in different ways, and knowledge of the various roles that different nutrients have, and how to make the most of the efficiency and timing of application will give growers the best chance of arriving at a good result for each growing season.
