A company admitted a breach in health and safety regulations following the death of a 21 year-old man, who died while cleaning out a grain silo.
Student Arthur Mason, 21, had climbed inside the silo at Hall Farm, Fincham, after he was instructed to clean it with a broom.
He was wearing a harness, but died after he sank under the tonnes of wheat in the silo.
An earlier inquest concluded that Mr Mason, of Eastmoor, King's Lynn, died accidently on July 9, 2014.
The company, represented by barrister Mark Balysz at Norwich Crown Court, admitted one charge of breaching health and safety regulations, by failing to ensure the safety of Mr Mason.
Judge Katharine Moore adjourned sentence until March 10 and said the company would get full credit for its guilty plea.
Mr Mason was a keen rugby player and student at the University of Gloucestershire, and was working on the farm during the summer break.
