Apport de matières fertilisantes avant plantation de vigne. Résultats d'un essai en sol de Graves du Bordelais

Abstract

In an open-field assay on a sandy, gravelly soil quite degraded the influence of addition of some fertilizers on the vine, before planting, was studied.

A complete basic fertilizer with joined organic, calcary and phospho-potassic elements enhances plant development and gives a normal crop yield four years after planting. No or incomplete basic fertilizer leads to very low crop yields and is followed by a replacement of a large number of vinestocks.
