298: How Cover Crops Shape Grapevine Root Systems

Root systems are more than just anchors, they are the plant's stomach, communicating with their environment through a network of microbes. Suzanne Fleishman, Assistant Professor of Root Biology at Penn State University, introduces the emerging field of Root Agroecology, which integrates plant physiology and omic methods to improve sustainability in vineyards. She shares insights from a five-year red fescue cover crop trial showing reduced pruning weights and improved vine balance, as well as shifts in rhizosphere microbiomes. Her future goal? A grower tool that predicts the best cover crops by site.  Resources:   72: Soil Microbes and Nutrient Availability  151: The Role of the Soil Microbiome in Soil Health  159: Under-Vine Vegetation to Control Vine Vigor  Can Cover Crops Improve Wine Grape Production Resilience?  Research revealing grapevine root relationships  Root Agroecology Lab  Suzanne Fleishman  Suzanne Fleisman – Google Scholar   Suzanne Fleishman – Research Gate  Undervine groundcover substantially increases shallow but not deep soil carbon in a temperate vineyard  Support the Podcast: Make a Donation  Vineyard Team Programs:  Juan Nevarez Memorial Scholarship - Help students from vineyard families pursue higher education  Online Courses - Earn DPR and CCA hours with expert-led sustainability trainings  SIP Certified - A trusted third-party certification proving your sustainable practices with science-backed standards  Sustainable Ag Expo - Join top experts at the premier winegrowing event of the year  Vineyard Team Membership - Connect with a community advancing sustainable winegrowing
