What to know about Simple vineyard growing practice impacts soil microbiome deep below surface

A study by Penn State researchers found that planting grass between vine rows alters the soil microbiome beyond the root depth of the grass, potentially affecting vine health and soil sustainability. The research suggests that groundcover can improve long-term vineyard management by enhancing soil health and reducing erosion.
