Small Vineyard Practices for a Hotter, Drier Climate
Tablas Creek Vineyard, Paso Robles - February 27, 2020

                                           Held as part of the 2020 California Small Farm Conference
Soil health principles lie at the core of management decisions that emphasize grape quality and long term resilience for small vineyards. These practices that aim to impart beneficial qualities to soil such as water holding capacity, infiltration, microbial activity, fertility and erosion control are becoming increasingly important in the face of the unprecedented challenges associated with climate change. During the field day, we will discuss the variety of ways small vineyards are balancing soil, water, and quality considerations in anticipation of rising peak temperatures and shrinking water supplies.

No-till and Cover Crop Management with Grazing
Tablas Creek Vineyard, Paso Robles - June 13, 2019

As a participating vineyard in the Cal Poly Healthy Soils Project, Tablas Creek is serving as a demonstration site to investigate the links between soil building practices such as no-till and grazing of cover crops, and measures of soil carbon, water holding capacity, and greenhouse gas emissions. During this demonstration field day, Tablas Creek vineyard managers discussed their unique soil management strategy, Cal Poly researchers discussed the preliminary findings of their field trials, and additional guest speakers discussed integrated approaches to soil management.
