Nitrogen fertilization of "Chardonnay" grapevines: yield, must composition and their relationship with temperature and rainfall.

Nitrogen fertilization of "Chardonnay" grapevines: yield, must composition and their relationship with temperature and rainfall.

In soils rich inorganic matter(OM), such as those in the elevations of South Brazil, themineralized N from organic matter does not always meet the N demands of grapevines, thus, N applications are necessary during vinegrowth. However, the optimal N rate to achieve satisfactory yield and desirable grape enological composition is not known.
