Soil Is Alive: Elaine Ingham's Legacy

Elaine Ingham was a microbiologist who helped people see that soil is a living system called the soil food web. Over four decades she taught farmers and gardeners to measure and boost soil life, and her ideas have been used in many countries. She founded Soil Foodweb Inc in 1996 and later launched the Soil Food Web School. She co-authored the Soil Biology Primer for the U.S. Natural Resources Conservation Service.

She died on February 16, 2026, in Fort Mill, South Carolina, at 73 years old, and she had retired in October 2025. Her teaching included compost, compost tea, and microscopy so people could observe soil microorganisms. Although some methods have been debated, many growers have reported improved soil health and plant growth after using biological approaches that she promoted. Her work has been cited in farming education and continues to influence soil conservation and regenerative agriculture. She was known for teaching microscopy and for promoting compost tea in her workshops. Many soil labs and educators still use her image of the soil food web in teaching. Her legacy remains.
