The Royal Norfolk Show's chief executive has said the demand for trade stands has been "extremely strong" despite the tough economic climate.
The event, which is thought to be the biggest two-day agricultural show in the country, will take place on 29 and 30 June.
The site at Costessey hosts more than 650 trade pitches, and 93,500 people entered the gates in 2010.
Chief executive John Purling said: "We've been very pleasantly surprised."
"All the space has sold and the demand for exhibitors in the livestock competitions and the equine competitions has been extremely buoyant too."
However, Norfolk County Council is halving its budget for this year's show due to financial constraints.
