Sub-level
Lower Main level refers to a landscape that natural area , part of the Rhein-Main-Lowland is, in the system of the Handbook of natural physical in Germany it is the main unit 232. It extends along the Main River and south of the river from Aschaffenburg in the east to the downtown Mainz in the west. In the east it borders on the Spessart , in the northeast on its flat foothills, in the northwest on the Taunus , in the west on the Rheinhessische Hügelland and in the south on the Odenwald foothills and these themselves.
geography
location
The sub-main level comprises the central part of the Rhine-Main lowland along the north curve of the lower Main as well as the large flat areas within the curve. The height usually fluctuates between 90 and 150 m above sea level. NHN , it only rises above this range on a few elevations and only falls below this range in a few depressions.
It begins as a first still narrower and north running strips at Worth in Bavarian Unterfranken and still expands before also under Frankish Aschaffenburg from which the rechtsmainische downtown area just to count, on the left of the Main along the lower valley of Gersprenz in Hesse greatly from to include Dieburg . From Aschaffenburg to around Hanau , where the bow of the Main in the Hessian region has almost reached its summit, the right-hand border of the natural area also moves further away from the river, while the left-hand border to around Heusenstamm approaches the river again a little. In the second part of the arch, the right border from the Main runs very close to the river axis, while the left Main sections extend southward beyond the border of the Main catchment area to the northern districts of Darmstadt . The westernmost parts of the natural area in Rhineland-Palatinate lie between Nackenheim and the mouth of the Main near Mainz in a narrow strip on the left bank of the Rhine .
The following neighboring natural areas adjoin one after the other in a counter-clockwise direction: On the eastern edge of the uppermost tip of the Lower Main Plain lies the Spessart , in front of which the Büdingen-Meerholzer hill country pushes itself before Kahl am Main , which is replaced by the Wetterau north of Hanau , which is now joined by the Main-Taunus foreland from Frankfurt to the mouth of the Main; the last three natural areas are also part of the Rhine-Main lowlands.
Behind the narrow western border, including through the city center of Mainz, the Rheinhessen table and hill country rises beyond the Rhine .
The Hessian Rhine Plain lies along the southern border from the Rhine to Darmstadt . Between Darmstadt and Dieburg, the Messel hill country jumps northwards into the arc of the Lower Main Plain, while from Dieburg the Reinheim hill country borders almost to the upper Main Valley tip in the south ; the last two natural areas are again parts of the Rhine-Main lowland. The Odenwald rises to the left of this short peak of the Main Valley .
Natural structure
The sub-main level is divided on the first level into the Rhine-Main valley around the mouth of the Main, the western sub-main level and the eastern sub-main level, which border each other at Frankfurt and Offenbach. In detail::

Soil nature and use
The sub-mine level is ecologically and economically shaped on the one hand by forestry, on the other hand by fruit and arable farming. Their mostly sandy soils are poor in loess and contain comparatively few nutrients. A large proportion is built over with settlement areas from the Rhine-Main conurbation .
