In a slurry to delegate

Alistair Boxall, a pollution researcher at Cranfield University, has strong ideas about academic leadership. Faced with an experiment in which chemicals were to be added to 70,000 litres of pig slurry and applied to a 1.5ha field in Derbyshire, he said: "I made full use of my powers of delegation. My PhD students found themselves in full charge of that part of the project."
