Abstract

For the southern Sahara and the Sahelian zone of the Republic of Niger, a regular occurence of dust sediments has been proved. As for the southern Sahara, two sedimentary cycles are documented. Between the ancient dunes of the Sahel, (Para-) Vertisols having formed on aeolian very fine-grained sediments as well, already occur in the scope of the 300-mm-isohyetal line. Due to their water-retaining capacity, these soils provide the only locations at the agronomic dry margin where the cultivation of vegetables is possible
