Nutrition is one of the important components of vineyard management. · Nutrition has the potential to influence various factors related to the production of , vine such as , fruit set, the quality of the fruit and the quality of the final product.
· Nourishing any , crop, including wine grape varieties, is not a simple task.
· The need to take into account factors such as the underlying , the soil type , the irrigation method , Mrs. , means that the development of a generalized program to suit all , cases is not feasible.
· In order to draw up the appropriate nutrition programme for each vineyard and for each variety separately ,, producers should understand the function of the nutrients applied in the vineyard and know its management history.
· Information on soil (e.g. , PH , structure, etc.) , on the role of nutrients in the plant and on the characteristics of varieties and subjects must be taken into account in order to successfully determine the nutritional needs of each vineyard.
The role of nutrients within the plant is essential information for the development of a balanced nutrition program for each , vineyard, but it is not the only information required to achieve the desired results.
* Nutrients are found in nature in various forms of ,, but plants generally show selective preference for some of these forms. For example, nitrates and ammonium ions are forms of nitrogen, but in general, nitrates are more available to the plant than ammonium ions.
The availability of nutrients is often determined by the properties of the soil. The presence of microorganisms in the soil can help convert nutrients into forms available for plant absorption.
The variety and the underlying used play a key role in determining nutrient requirements. Vivid subjects are more capable of securing the necessary nutrients from the surrounding soil. This means that they require less nutrients.
· The need to take into account factors such as the underlying , the soil type , the irrigation method , Mrs. , means that the development of a generalized program to suit all , cases is not feasible.
