The objective of the course is to provide the basis for engineers to create technical solutions to society and agricultural problems without compromising soil functions.
This course will focus on the primary threats to the functions of the soil and how and why processes affect the soil and influence the human society. It will cover soil physics including a description of the soil as a three-phase system. The properties of water, the theory of capillarity, and the principles of soil water content and potential will be presented. The flow of water, the transport of solutes, and the movement and exchange of gases will be studied, and the physical principles of soil temperature and heat conductivity will be presented. The fundamental concepts of mechanical stress and strength of soil bodies will be covered including stress-strain relations. The structure of the soil and the concepts of aggregation will be discussed. The properties of the colloidal fraction in the soil will be introduced and the fundamentals of the soil-plant-atmosphere continuum will be presented
