Different CONTENT
Source=[Soil formation, pedogenesis and soil profile development. Soil structure, bulk density, texture, porosity, organisms and the effect of organic amendments. Soil properties - clay minerals, surface charges, aggregate formation and stability. Soil management - maintenance of soil structure, land management. Soil hydrology - water potential, movement of water. Soil conservation - problems created by salinity, sodicity and erosion. Sustainability of soil-plant systems, with emphais on the role of soil phosphorus, carbon, nitrogen, sulphur and potassium.]
