Growers of cold-hardy grape cultivars are currently relying on mineral nutrition and soil management practices developed for Vitis vinifera or V. labrusca. Therefore, Carl Rosen and James Crants at the University of Minnesota are leading the effort to develop this information specifically for cold-hardy grape cultivars. Soil and tissue samples, as well as yield data (including juice chemistry analysis) are being collected in 15 sites in IA, MN, NY, ND, and SD, focusing on Marquette, Frontenac, and La Crescent.

This issue of News You Can Use contains links to a webinar and a newsletter article that cover the basics of soil fertility and appropriate methods for collecting soil and tissue samples, as well as interpretation of the results:
