It lies in the flat fen country, on the river Nene (mainly on the east bank), II m.
It is best adapted for application to clays and fen lands and should not be practised on shallow light sands or gravelly soils, since the humus so necessary for the fertility of such areas is reduced too much and the soil rendered too porous and liable to suffer from drought.
It was separated from the sea by a belt of marsh and fen uniting Friesland and North Holland, the original coast-line being still indicated by the line of the Frisian Islands.
Since that time the great changes produced by the drainage of the fen-country have banished this species from nearly the whole of it, so that R.

The main feature of the northern plain is the so-called Luneburger Heide, a vast expanse of moor and fen, mainly covered with low brushwood (though here and there are oases of fine beech and oak woods) and intersected by shallow valleys, and extending almost due north from the city of Hanover to the southern arm of the Elbe at Harburg.
Southward, the Danube encircles a vast fen, tenanted only by waterfowl and herds of half-wild swine, while the plain which extends to the north-east and east only grows fertile at some distance inland.
Owing to the shrinkage of the soil in reclaimed lands, however, that is, lands which have been drained after fen or other reclamation, the sides of the polder are often higher than the middle, and it is necessary by means of small dams or sluices to make separate water-tight compartments (afpolderingen), each having its own unit of measurement.
West, north and north-east of this the province is flat and consists of sea-clay or sand and clay mixed, except where patches of low and high fen occur on the Frisian borders.
A large part of this has been reclaimed and the sandy soil laid bare, but on the Drente and Prussian borders areas of fen still remain.
Deep. The drainage of the Great Level of the Fens was prosecuted during the 17th century, but lack of engineering skill and the opposition of the fen-men hindered the reclamation of a now fertile region.
On the clay and low fen cattle-rearing and the making of the Gouda cheeses are the principal occupations.

A pamphlet on the cultivation of osiers in the Fen districts is issued in England by the Board of Agriculture.
It is peculiarly adapted for peaty soils, and is accordingly a favourite crop in the fen lands of England, and on recently reclaimed mosses and moors elsewhere.
Groningen communicates with the Lauwers Zee by the Reitdiep (1873-1876), while the canal to Winschoten and the Stadskanaal, or State canal (1877-1880), bring it into connexion with the flourishing fen colonies in the east of the province and in Drente.
These include various local lines such as the line AlkmaarHoorn (1898), Ede-Barneveld-Nykerk, Enschede-Ahaus in Germany (1902), Leeuwarden to Franeker, Harlingen and Dokkum, and the line Zwolle-Almelo (junction at Marienberg) Koevorden-StadskanalVeendam-Delfzyl, connecting all the fen countries on the eastern borders.
Horticulture and market-gardening are of a high order, and flourish especially on the low fen soil and geest grounds along the foot of the dunes in the provinces of North and South Holland.
