Harriet Mella

Harriet Mella is an independent researcher from Austria specialising in soil microbiology, mycology, and biochemistry. With a deep understanding of how microbial networks, mineral balance, and carbon cycling shape plant health, she works at the cutting edge of applied soil science. Harriet is known for her ability to translate complex scientific concepts into clear, practical guidance for farmers, advisors, and land stewards.

Her work focuses on profiling soil and plant conditions — including nutrient dynamics, pest and disease pressures, and water-use patterns — to design management strategies that optimise plant growth and build long-term ecological resilience. She collaborates closely with farmers across different climates and soil types, from Europe to Australia, where producers value her rare ability to connect advanced soil science with real-world production challenges.

Harriet’s research and advisory work emphasise the integration of microbes, minerals, and organic matter to enhance soil function, improve nutrient availability, and increase crop and livestock resilience under stress. At Northern Roots, she brings a unique systems-based perspective, offering insights into how healthy soil biology can drive both productivity and sustainability in modern agriculture.
