Grapevine nutrient status is an important influence on grapevine performance.
Making quantitative estimates of fertiliser applications necessary for remedial action where vine nutrition limits vine performance is difficult.
Current research aims to imrpove the interpretation of petiole analysis by devising a vigour index to remove the effect of vigour on petriole nutrient concentrations and thus make subsequent decsions more precise by establishing updated guidleines for soil nutrient availabilities.
