Cover crops play a critical role in building healthy, resilient soils in vineyards and agricultural systems. Sarah Light, Agronomy Farm Advisor with UC Cooperative Extension, shares how cover crops protect soil from wind and heavy rain, improve water infiltration, and increase on-farm biodiversity. She introduces a newly released cover crop selector tool developed for Western growing regions, with guidance on species selection, termination practices, and grower goals such as reducing compaction, fixing nitrogen, and supporting pollinators. This practical resource helps growers choose the best cover crops for their location, crops, and management objectives.

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.
