This video covers research on water dynamics while a new table grape vineyard was established with cover crops in the San Joaquin Valley. There are two cover crop treatments, one with native plant species and another with introduced plant species. The native mixture was dominated by Tansy Phacelia and the introduced mix was dominantly Merced Rye. Both cover crops are known to contribute to soil health and the Phacelia had early positive impacts on the soil biota and soil water content.
