Soil Genesis and Development, Lesson 4: Soil Profile Development
The processes occurring over time in a soil are reflected in vertical and lateral physical and chemical characteristics of that soil. The four soil forming processes, in conjunction with the five factors of soil formation, organize parent material into a soil profile that consists of soil horizons....

| Summary: | The processes occurring over time in a soil are reflected in vertical and lateral physical and chemical characteristics of that soil. The four soil forming processes, in conjunction with the five factors of soil formation, organize parent material into a soil profile that consists of soil horizons. These processes can occur over millennia; however, they can also be influenced by short‐term variables such as human use. Understanding the processes enables interpretation of the natural history of a soil and provides a starting point to evaluate how future changes will affect the soil resource. Combining landscape history with knowledge of principles of soil profile development allows for more precise and effective land use planning, from residential development to precision agricultural practices. |
