Soils: Sustainable Ecosystems
Standard letter grades
Total contact hours
Focuses on soil science basics, from physical properties to use and management. Discusses traditional agricultural, wildlands and rangelands, watersheds, and modern environmental perspectives on soil. Reviews new soil applications and soil science to better understand the role soil has in our lives. Includes lab component with indoor and outdoor experience and field trips.
Course learning outcomes
1. Explain the importance of soil texture and demonstrate methods to determine texture.
2. Explain a soil’s classification based on its horizons and profile.
