TED Tech The food that fertilizes itself | Giles E.D. Oldroyd
May 9, 2025
Join plant scientist Giles E.D. Oldroyd as he uncovers the remarkable potential of soybean plants to thrive without synthetic fertilizers. He reveals how these plants form symbiotic relationships with fungi and bacteria, enhancing nutrient access and promoting sustainable farming. Oldroyd discusses genetic innovations aiming to unlock nitrogen-fixing capabilities in non-legume crops. The conversation also explores how companies are developing microbial solutions to improve yields and protect the environment, reshaping the future of agriculture.

Episode notes
Soybean's Natural Fertilizers
- Soybean plants have root nodules with bacteria that fix nitrogen from the air into a usable form.
- They also partner with fungi that enhance nutrient uptake, enabling virtually self-fertilization.
Reintegrating Fungi in Agriculture
- Agricultural crops currently rely heavily on inorganic fertilizers, causing pollution and costs.
- Re-engaging crops with beneficial fungi can reduce fertilizer use and environmental damage.
Rewire Crops for Fungal Partnership
- Rewire crop genetics to proactively engage beneficial fungi even when fertilized.
- This approach can maintain yields while lowering fertilizer application and nutrient loss.
