Summary:

My research is focussed on making crops more productive by improving soil quality. 

This research is funded through my NERC Soils Security fellowship (2016 – 2019) entitled ‘Ploughing on Regardless?’ which enabled me to establish one of the first zero tillage field trials in the UK.  In addition, this research makes the most of the state-of-the-art facilities at Rothamsted including stable isotope tracing, molecular biology, trace element speciation analyses and systems modelling, in order to produce cutting edge research with real impact.

In terms of impact, I am working with the AHDB monitor farm network (2016 – 2019) on soil health, specifically to translate plot scale tests to field scale use.  I have previously contributed to the BBC Countryfile magazine, BBC One show, South East Today and national events such as Cereals and Groundswell. 

I will be showcasing our earthworm and tillage research on the Rothamsted stand at Cereals (2017) this year, so if you have any questions about soil health please do come and find me and I’ll be happy to help.
