Course Learning Outcomes

1. Define and give examples for terms as they relate to soils, soil composition and components, soil nutrients and the tools and procedures used for sampling and testing.
2. Systematically apply several methods for analysis and recognition of a variety of soils commonly found in Upstate, Central, and Western New York State (Ex. Cultural characteristics and/or land use groups).
3. Classify a selected number of soils into their cultural characteristic or land use groups in preparation for practical application (Ex. land use careers and problem diagnosis).
4. Evaluate the effects of man-made and natural influences on a variety of soil and environmental conditions.
