Book 1998 the earth‘s crust that is exploited by plant roots for anchorage and supply of water and nutrients. Soils are complex natural bodies formed under the influence of plants, microorganisms and soil animals, water and air from their parent material, i.e. solid rock or unconsolidated sediments. Physical

Why Soil Genesis?orizon decreases or increases, sedimentary layering disappears, etc. Mostly, such changes are slow, and can be seen only after decades to millenia. So most soil properties that change during soil formation are relatively stable. Sometimes, however, effects of soil formation can be seen within weeks

Soil Physical Processesture gradients and fluctuations, and shrinkage and swelling. Here a short outline of such processes will be given. For more details on the principles involved in the movement of water through soils, reference is made to introductory tests as such in 2.7.

Studying Soil Profilessystems (FAO-Unesco and Soil Taxonomy). You will be able to describe the formation of these diagnostic horizons, and thereby, of the different genetic soil types, in terms of the physical, chemical and biological processes you studied in Part B.
