The course of study represents the fourth of six modules in advanced crop and soil science and introduces the agriculture student to the topic of soil water. Upon completing the three day module, the student will be able to classify water as to its presence in the soil, outline the hydrological cycle, list the ways water is lost from the soil, define leaching and its measurement, list means of controlling evaporation, and apply the basic principles concerning soil water to management situations. The course outline suggests teaching procedures, behavioral objectives, teaching aids and references, problems, summary, and evaluation. Following the lesson plans, pages are coded for use as handouts and overhead transparencies. A materials source list for the complete soil module is included. (MW)
