Bob Tillman is a former electronics professional who launched Alta Colina Vineyard & Winery in 2003 on the steep, mountainous terrain of Paso Robles, California . Managing thirty-two acres of grapes, he has spent two decades transitioning from conventional methods to a biological approach centered on the natural resilience of his native ecosystem.
He eliminated tillage in 2006 and moved away from synthetic inputs to rely on native ground cover and biological cycling . By utilizing total nutrition testing, he identifies vast mineral reserves already present in his soil and focuses on microbial health to make those nutrients available to the vines
In this episode, John and Bob discuss:
-
Tranisitiong to a completely no-till system after observing that native grasses were more effective and resilient than planted cover crops .
-
How nutrition testing revealed that the soil contains enough potassium for over six hundred years and enough iron for millions of years of production .
-
Utilizing AEA and sap analysis to identify specific micronutrient deficiencies and adjust nutrition throughout the growing season through foliar applications.
-
Applying AEA products like CalGuard and Rebound Boron helps address seasonal trending deficiencies in calcium and boron levels .
-
How the vineyard uses compost extracts and teas to inject biological activity directly into the soil through the irrigation system .
-
High-density native plant populations providing ground cover that supports deep-rooted vines while maintaining high soil organic matter .
