Celebrate Healthy Soils Week
December 4 – December 8, 2023

Follow us on social media: #HealthySoilsWeek2023.

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

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.

American Farmland Trust logo

American Farmland Trust is documenting economic and environmental benefits of soil health practices with farmer profiles, case studies, webinars, and on-farm soil analysis trials with almonds, mixed crops, wine grapes, and wheat.

American Farmland Trust’s farmer profiles document how vineyards in Napa and Sonoma Counties boosted their bottom line by thousands, increased their biodiversity significantly, and reduced their water usage by approximately 40 percent with various soil health

Ca Almonds logo
Almond Board of California (ABC) promotes cover crops with a case study of one orchard in Stanislaus County, where cover crops have been planted for a decade. The study demonstrates return on investment, based on a calculator system developed by the American Farmland Trust.
