One of the largest blocks of grade one silt in the West Norfolk Fens to be sold on the open market for some years has a price tag of £15.75m.

The 1,625-acre Nordelph Farm is a commercial arable holding, which lies in a single block between Downham Market and Wisbech.

The farm, which is on Upwell Fen, has large, level fields, which average about 60 acres.

The agent, Strutt & Parker, has indicated a guide price of £9,692 an acre or £15.75m for Nordelph Farm.

It has two main ranges of buildings, with a total of 3,200 tonnes of grain storage in three buildings and a 1,300-tonne refrigerated box potato store with grading shed.

The entire farm can be irrigated and towards the southern end, it has a reservoir with 15m gallon capacity, filled by a winter licence.

There is a second licence for a further 60 million gallons of winter abstraction to a reservoir, which has not yet been constructed. The ditches are also used to distribute water around the farm for spray irrigation.

It also grows a range of high yielding crops including wheat, potatoes, sugar beet, cereals and field vegetables and has a total of 1,585 acres of cultivated land.

It is a continuous block of Grade 1 farmland extending to about 1,618 acres, of which 1,585 acres are croppable.

The land has good access roads as well as a good network of farm tracks.

The entire farm is classified grade one 1 by Defra and the soils include Wisbech Series, which is a marine alluvium providing deep, stoneless coarse silty soils.

The other soil types include stoneless clay soils, often over peat.

The only main house, Woodhouse Farm, has not been occupied for many years and needs complete refurbishment but could be modernised as a possible home for a farm manager.

There is a pair of semi-detached three-bedroom cottages, currently rented, for a total of £10,500 a year.
