Soil Science (SOIL)

210 Soil Science (4 - Fall, Spring) The nature and properties of soils. Provides an introduction to the characteristics of soils. Discussions of the biological, chemical, and physical processes which occur in soil and how these processes affect plant growth and environmental quality. Three one-hour lectures and one two-hour lab. Prereq: CHEM 121 or consent of instructor.

250 Soil and Landscape Evaluation (1 - Fall, Spring) Principles of soil morphology as utilized in soil and landscape evaluation in the field. Involves describing, classifying and interpreting soil in preparation for regional and national soil judging contests. May be repeated. Maximum four hours. Prereq: Consent of instructor.

301-302 Special Problems (1, 1 - Fall, Summer and Spring, Summer) Individual problems for students exhibiting special interests and abilities in soils, soil morphology and classification, soil fertility, management, and conservation. Maximum of one hour applicable to concentration requirements. Written project outline and report of results required. Taught only by arrangement prior to registration.

315 Soil and Water Conservation (3 - Spring) Problems, principles, and control of soil erosion by water and wind; land planning for soil conservation: water management, including irrigation and drainage problems: philosophies of land ethics and stewardship. Students are required to write reports and give oral presentations. Three one-hour lectures . Prereq: SOIL 210.

321 Soil Genesis, Morphology and Classification (3 - Fall) Study of the soil as a natural, three-dimension system: the effect of geologic, climatic, and biotic interactions on soil characteristics and processes of formation and methods of classifying soils. Two one-hour lectures and one three-hour lab. Prereq: Soil Sc 210.

401-402 Research Participation (3, 3 - Fall, Summer and Spring, Summer) Research project involving supervised independent study for students exhibiting special interests and abilities in the soils area.
