      First Stop: Blossom Vineyards

      First Stop: Blossom Vineyards

      Frank Olagaray took over his parents' 55 acres of land in Thornton, CA, in 1996 and in the decades since has grown it to more than 1,400 acres. Much of the clay loam soils he acquired over the years were deficient in calcium, potassium and phosphorus – having had minerals taken out for years but never replaced.

      Soil expert Glen Rabenberg, of Soil Works LLC, worked with Olagaray to correct the cause of his soil issues, rather than reacting to the symptoms. Through this, Olagaray was able to start rebuilding his soil and is now getting stronger yields. Today the farm grows 940 acres of wine grapes, 280 acres of olives for olive oil, 135 acres of organic walnuts and and 128 acres of organic almonds.

      Join soil consultant Glen Rabenberg and owner Frank Olagaray for an insightful walk through this gem of a farm – learning about the soil strategies that brought this soil back to life and how to identify problems in the field in order to address them successfully.

      Second Stop: Marrone Bio Innovations
