This 5-minute video interview with Professor Giles Oldroyd offers a thought-provoking take on the topic of fertilisers and nitrogen fixation. 

In the west, we’ve spent 50 years relying on increasing food yields by adding nitrogen-based fertilisers to the soils. But it’s not an approach that seems to be working for the millions of smallholder farmers across western and central Africa. Local farmers, agronomists and scientists from across the world are working together to find innovative solutions.

In this video interview, Professor Giles Oldroyd of the John Innes Centre discusses his research.

The accompanying notes include a teachers' summary, plus student questions and answers.
