Celebrate Healthy Soils Week
December 5 – December 9, 2022

Follow us on social media: #HealthySoilsWeek2022.

Join the California Department of Food and Agriculture and our many partners in highlighting soil health! Dates will be added soon to see activities and events scheduled for each day. We will be updating and adding to the Healthy Soils Week calendar over the next few weeks, so bookmark this page and check back often.

Why Healthy Soils?

Healthy soil is quite literally the foundation of sustainable food, water, air and biodiversity. Restoring and preserving healthy soil results in:

  • Improved plant health and yields
  • Increased water infiltration and retention
  • Sequestered carbon and reduced greenhouse gases (GHGs)
  • Reduced sediment erosion and dust
  • Improved water and air quality
  • Improved biological diversity and wildlife habitat

Webinar: Building Belowground Biodiversity

Webinar with CDFA Secretary Karen Ross and members of the Belowground Biodiversity Advisory Committee (BBAC). The committee is made up of world-renowned scientists. To better understand how soil biodiversity may impact soil health, The committee is charged to prepare a report with their recommendations on biodiversity indicators as a proxy of soil health and ecosystem functions. This webinar will discuss the importance and impact of belowground biodiversity on soil health and presenters will also share some of the work they have completed.

Tuesday, 12/6

NRCS Webinar: Web Soil Survey Presentation

Hosted by California NRCS, the Web Soil Survey (WSS) provides soil data and information produced by the National Cooperative Soil Survey. It is operated by the USDA Natural Resources Conservation Service (NRCS) and provides access to the largest natural resource information system in the world. NRCS has soil maps and data available online for more than 95 percent of the nation’s counties. Moderated and presented by Phil Smith, California NRCS Area Resource Soil Scientist, and Tony Rolfes, California State Soil Scientist. This is a presentation on WSS and other Soil Web Tools for gathering soils information and maps.

Community Alliance with Family Farmers and Wild Farm Alliance – Field day at Double A Walnuts in Colusa, CA

Field day to discuss cover cropping, hedgerows, and practices for improved orchard management. Benefits and challenges of cover cropping and hedgerows; implementing nematode-resistant root systems and improved irrigation systems; demonstrations of inoculating and broadcast planting of cover crop seed; demonstration of a small mower that is great for managing weeds in the strips of tree rows. We will also share resources for farmers to support the implementation of such practices.

Additional Healthy Soils Resources

NRCS logo

NRCS Videos: a "Soil Tunnel," an in-field soil health assessment, and a rainfall simulation all bring home the importance of what goes on below the soil surface.

  • A Walk Through the Soil Tunnel (5:06 min.) The Soil Tunnel is an educational tool designed to teach and promote the importance of soils and soil health. It illustrates through the use of images, the important functions of the soil. Through this interactive soil exhibit, audience of all ages can view the world below the ground by walking through the Tunnel.
  • NRCS Cropland In-Field Soil Health Assessment Overview, Part 1 (17:58 min.) The Cropland In-Field Soil Health Assessment is designed to be used as a diagnostic tool to help conservation planners determine if soil health resource concerns exist.
  • NRCS Cropland In-Field Soil Health Assessment Overview, Part 2 (16:35 min.) (see above for description)
  • NRCS Rainfall Simulator Demo (10:29 min.) The Rainfall Simulator provides a demonstration of how practices such as no-till farming, cover crops, and prescribed grazing benefit soil health and improve the water cycle on cropland and rangeland. Presented by Dr. Zahangir Kabir, NRCS Regional Soil Health Specialist.
  • NRCS-RCPP announces funding is available for San Joaquin Valley farmers to implement 14 conservation practices that save water and build healthy soils. American Farmland Trust has information about what’s covered, and where to get more help in multiple languages.
