The aim of this paper is to investigate spatial variation of soil chemical properties at an intermediate scale. It is proposed that there is an association between the different vegetation and soil surface (soil and biotic crusts) units
and the underlying soil chemical properties; that bare areas have a relatively larger soluble salt concentration compared to the vegetated areas. A model that explains this distribution, and incorporates vegetation, microtopographic and infiltration differences
