NR 701 Advanced Soil Physics Jordan University of Science & Technology Faculty : Agriculture Department : Natural Resources & the Environment Semester : First 2004/2005 Place : A3 132 Time : 1 1.15-12.15 Sun Tues Thurs Instructor : Dr. Nabil Eltaif General Course Objectives: To examine and understand the quantitative aspects of soil physics particularly in relation to the transfer of energy, gas, water, solids in soil. Also, to provide a basic understanding of soil physical properties and processes, with emphasis on their importance and applications to agricultural problems. What you are expected to learn from this course: This course will enable the student to understand how the soil, plant, and engineering sciences utilize knowledge of soil physical behavior and to develop mathematical and quantitative skills needed to solve applied problem in soil science. Emphasis will be placed on understanding how soil physical properties impact on agriculture, natural resources, and the environment. Course Content: Weeks 1-2 Subject Introduction to the subject, characterization of and relationships between the soil solid, liquid, and air phases. 3-4 Clay minerals, particle size analysis, Stoke`s law, surface area, measuring specific surface area 5-6 Soil structure ,classification , flocculation theory, swelling & dispersion of clay minerals, factors influencing soil structure, measurement of soil structures . 7-8 Soil water, status of water in soil, concept of potential, mechanisms of water relations, Hysteresis, measurement of water content and potential . 9-10 Water movement in soil, Darcy`s law, application of Darcy`s law . 11-12 Flow through saturated soil, Laplace equation, application of Laplace equation, diffusivity flow through layered soil . 13-14 Soil gas phase, composition, diffusion, mass flow, Fick`s law, measurement of gas exchange . 15-16 Thermal relationship, soil thermal properties, temperature and heat flow . The attention given to each of these topics may be adjusted based on student background and interests.
