Soil forming processes time is an important consideration since the soil forming factors must act for a considerable period to develop a mature soil profile. Each soil forms as a unique expression of five soil-forming factors (climate, vegetation, topography, parent material, and time) that work through soil processesthese soil processes can be considered in the following four groups: additions, losses, transformations, and translocations. Horizons are the visible evidence of soil-forming factors at work— climate, organisms, relief (topography), parent materials, and time scientists group soils based on the arrangement and properties of horizons. The five soil forming factors thirty thousand years of soil formation in 5 seconds mineral material such as volcanic ash: weathered rock or alluvium.

Soil system’ jenny h (1941) factors of soil formation mcgraw-hill book co inc pp281 the parent material can influence the soil in a number of ways: • colour •texture •structure • mineral composition • permeability/drainage this soil has developed on old red sandstone and so has derived its distinctive colour from its parent material. Soils develop as a result of the interactions of climate, living organisms, and landscape position as they influence parent material decomposition over time these five factors are called the factors of soil formation differences in these factors influence the soil-forming process.

The interaction of the five soil-forming factors time, climate, parent material, topography, and plant and animal life, result in the development of a soil profile a soil profile is a vertical section of the soil beginning at the surface and extending down into the unconsolidated underlying material to a depth of 60 inches or more. Soil research has shown that soil profiles are influenced by five separate, yet interacting, factors: parent material, climate, topography, organisms, and time soil scientists call these the factors of soil formation.
