Introduction
Jenny(1941)
-First formalised the role of different factors in soil development.
-Soil type = f {parent material, climate, biological activity, landform, time}

Soil-forming factors
Soil development from parent material

Soil-forming factors
Influence of parent material
One of the strongest influences on soil development.
Influences properties of soil
Physical properties - soil texture
Chemical properties - dissolution and precipitation
The effect of parent material enables classification of soils
Residual soils - composition can be directly related to those of the underlying rocks
Depositional soils - develop on surface deposits which have accumulated at particular points.
