Nutritional requirements for maintenance of healthy vines and highest quality grapes

Recently, there have been reports of vines with poor vigour and weak growth, which may be a result of nutrient deficiency, compounded by overcropping. Low vigour can also be a consequence of excessive root damage, resulting from soil nematodes. This project will correlate vine nutrition and quality of grapes in a number of soils in the Okanagan/ Simlkameen and determine if nematodes play a role in vines showing poor vigour.
