Soil Moisture Monitoring in Vineyards - Demonstration (CIG)
This project's goal is demonstrate the use of soil moisture sensors to increase water use efficiency in vineyards in the Paso Robles Groundwater Basin. Three demonstration growers were assisted in adopting new irrigation management practices through the use of plant, soil, and weather data collection. The content from the demonstration sites were extended to a broader grower audience through tailgate meetings, newsletters, email lists, website, social media, fact sheets, presentations, and trade publications.

What is the most important factor in vineyard irrigation scheduling? Organization. Having defined company goals and someone in charge of holding the team accountable. Tom Shapland, Co-founder and CEO of Tule Technologies and Lucas Pope, Director of Operations at Coastal Vineyard Services share their top challenges and strategies to apply the right amount of water at the right time. Incorporating tools like soil moisture sensors, plant-based monitoring, weather data, and soil types helps farmers know how much water is reserved in the soil so they can irrigate efficiently without applying more than the soil can handle.
Greg Pennyroyal of Wilson Creek Winery and Vineyards was looking for soil moisture systems and found that the products available in the market were all expensive, proprietary systems that did not meet the needs of small block Temecula vineyards. He partnered with Reinier van der Lee, CEO of Vinduino, to reverse engineer the technology to develop a product that would give the same results for a fraction of the cost.

There is no doubt that water is a precious resource, particularly in drought prone regions like California. There are a bevy of technological devices available to utilize, from soil moisture probes to pressure bombs, but these tools only provide data on one specific area. Irriwatch founder and CEO Wim Bastiaanssen is aggregating data from 10 satellites to provide daily moisture measurements down to the pixel, allowing growers to optimize irrigation water applications in a world of dynamic weather, soil and crop processes.
While grape production does not require extensive water use and the majority of vineyards in the Pacific North West are drip irrigated, drought conditions in recent years have led growers to seek more efficiencies to reduce water use. Pete Jacoby, Professor of Crops and Soil Sciences at Washington State University is partnering with commercial growers to test a different sub-surface irrigation system - vertically placed PVC pipe.
We urge growers to submit individual comments on this draft. This draft is significantly different than prior Ag Orders and will require significant additional documentation and reporting for vineyards (both SIP Certified and non-SIP Certified).
Central Coast Water Board staff has developed a Draft Agricultural Order 4.0 to replace the current Agricultural Order 3.0 that expires on January 31, 2021. Please join Water Board staff at one of three stakeholder workshops to learn more about the Agricultural Order.
Spring 2020 Update: Agricultural Water BMP Adoption Project
Vineyard Team is a non-profit outreach and education organization based in Atascadero, California. The California Department of Water Resources (DWR) awarded a grant to Vineyard Team in 2017 to study grower adoption of irrigation best management practices in vineyards. Over three years 57 growers were recruited into the project.
