Abstract:
Pedological and edaphological properties of two soil associations forming a continuum from the Uluguru
\mountain ranges to the Mindu mountain in the Morogoro area, Tanzania, have been investigated. The general
/eatures of the area, including climate, geology and vegetation are discussed as is the movement of soluble salts
on the slopes and its effects on soil composition. The investigation shows that there is a close connection
between the three soil forming factors, climate, parent material, and relief and the mineral composition of the
soils and their edaphological properties. This means that a thorough understanding of the soil forming factors
and the soil development processes provides a key to land use evaluation of an area like this, where soil data
often are lacking.
