Observation of Soils Along the Lopit Mountains

Torit, Sudan

  

We travelled to Torit today.  The trip along the Lopit Mountains more or less confirmed my initial ideas about the soil catena.  I drew the catena as follows.  I have noted the typical agricultural use of each soil type as well as its normal natural vegetation.

I think there are quite a few places without a broad alluvial valley.  In these places, the red sandy soil generally grades into the drier soils of the plains.  Perhaps I am not detailed enough about the soils of the plains or need to subdivide them further.  I think that these soils range from sandy to darker clay.  Some areas are well drained others quite flat.  I have not had opportunity to carefully observe the soils further from the mountains and figure out crop-soil associations for them.   The road, poor as it is, runs along the mountains.   There are no roads further from the mountains.
