Research Description

The Opportunity

The UK sugar beet industry spends £12–18 million annually on nitrogen fertiliser alone, yet in some instances it has been shown that cover crops can provide 30–60 kg N/ha to the following sugar beet crop. Cover crops are often used ahead of sugar beet, but a lack of evidence about the nitrogen they provide and the factors that affect it means very few growers adapt their nitrogen application rates after using a cover crop, potentially missing out on savings of £30–70 ha. Some species immobilise nitrogen and suppress beet growth; others create a "green bridge" for virus-carrying aphids during the critical establishment period.

This PhD will deliver the first evidence-based framework for integrating cover crops profitably into UK sugar beet rotations, with the potential to unlock £3–7 million per year in industry-wide fertiliser savings. Funded jointly by BBRO, the Morley Agricultural Foundation, and the Lugden Hill Trust, this is an applied, industry-facing project: you will work closely with BBRO and the grower community throughout, ensuring research questions are grounded in real farming challenges and that outputs reach the people who need them.

What You Will Do

Working across agronomy, soil science, and microbial ecology, you will:

Run controlled decomposition experiments to quantify N, P, and K release from key cover crop species (cereals, brassicas, legumes, and mixtures) under UK conditions.
Establish multi-year field trials on contrasting soils at commercial BBRO sites and the University of Nottingham farm, measuring beet yield, sugar content, and pest/disease incidence.
Analyse soil microbial communities (PLFA, 16S/ITS sequencing) to understand how residues drive nutrient cycling and soil health.
Parameterise predictive models and translate outputs into practical grower tools, including a fertiliser credit calculator and species selection guide.
