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.
