Soil Chemistry, Nutrient Cycling and Soil Biology | Graham Lancaster

Graham Lancaster joins Soil Food Web School to talk Soil chemistry, nutrient cycling and soil biology!

This video will outline and explain the aspects of soil chemistry which sustains agricultural nutrient cycling. Soil biology is the key player in sustainable farming supporting soil chemistry and enabling nutrient cycling. Soil organic matter is the building block to support microbes and enhance soil chemistry.

Graham is the founding director of the Environmental Analysis Laboratory (EAL) at Southern Cross University, Lismore, Northern New South Wales, Australia, and now the senior manager of commercial and research services. EAL has been supporting sustainable farming for over 30 years and promoting all forms of soil management using the principles of biological, organic, regenerative farming.

The Soil Food Web School’s mission is to empower individuals and organizations to regenerate the soils in their communities. The Soil Food Web Approach can dramatically accelerate soil regeneration projects by focusing on the soil biome. This can boost the productivity of farms, provide super-nutritious foods, protect and purify waterways, and reduce the effects of Climate Change. No background in farming or biology is required for our Foundation Courses. Classes are online & self-paced, and students are supported by highly-trained Soil Food Web School mentors.

Over the last four decades, Dr. Elaine Ingham has advanced our knowledge of the Soil Food Web. An internationally-recognized leader in soil microbiology, Dr. Ingham has collaborated with other scientists and with farmers around the world to further our understanding of how soil organisms work together and with plants. Dr. Ingham is an author of the USDA's Soil Biology Primer and a founder of the Soil Food Web School.
