Factors which cause delay in soil formation are extremes of cold and dry climate impermeable and consolidated parent material incomplete weathered rocks and minerals high in lime and very steep slopes. These provide a base on which the active soil forming factors work or act for the development of soil.

Soils form from the interplay of five main factors namely Parent material Time Climate Relief and Organisms. Parent material climate biota organisms topography and time. Soils are often defined in terms of these factors as dynamic natural bodies having properties derived from the combined effect of climate and biotic activities organisms as modified by topography acting on parent.

Materials are deposited on their surface and materials are blown or washed away from the surface. Temperature and precipitation influence the speed of weathering of parent materials and thus soil properties such as mineral composition and organic matter content. These factors are climate and vegetation biosphere.
