Dr. Elaine Ingham, a pivotal figure in soil science whose work illuminated the intricate soil food web and its importance for ecosystems, died on February 16, 2026, at the age of 73. Her passing was confirmed in mid-February 2026, with tributes emerging across various platforms.
Ingham's legacy is cemented by her development of the 'soil food web' concept, a paradigm shift that moved the understanding of soil from a purely chemical medium to a vibrant, biological entity. She earned degrees in Microbiology from Texas A&M and Colorado State University, setting the stage for a career dedicated to this living earth beneath our feet. Her foundational research and advocacy empowered a global community of farmers, scientists, and environmentalists toward the restoration and sustenance of soil health.
Her family requests that those wishing to honor her continue her work by planting a tree or making a donation to the Soil Food Web Foundation.

A Life Dedicated to Living Soil
Ingham was widely recognized for her work in promoting aerobic compost and compost teas as soil enhancers. She championed the critical role of microorganisms – the bacteria, fungi, and other life teeming within the soil – in fostering healthy, sustainable ecosystems and, by extension, healthier crops and human well-being. This biological perspective contrasted sharply with earlier views that treated soil primarily as a collection of chemicals.
Beyond her academic pursuits, Ingham founded the Soil Food Web School and Soil Foodweb Inc., educational and business ventures designed to share her findings and practical applications with a broader audience, extending her teachings beyond traditional academic circles. She was described by some as the "Mother of Soil Microbiology," a testament to her profound influence. Her approach was characterized by an invitation to observe and test, rather than simply accept ideas.
