Catalog Description:
Untitled document
This course is an introduction to the science, ecology and management of soils. A key focus of the class is viewing soil health as the basis for ecological land management and discussing management practices to conserve and improve soils. Soil physical, chemical and biological properties and processes are all examined in detail through class lectures and discussion. The class laboratory focuses on evaluating soil health with field measurements, laboratory analyses, and calculations, including using soil testing to develop soil nutrient plans.

COURSE CONTENT

Student Learning Outcomes:
Untitled document
Upon completion of this course, students will be able to:
1. Discuss the importance of soil health to ecosystem services.
2. Explain soil physical properties and their influence on plant growth.
3. Explain the importance of soil organic matter and soil structure and propose management
    practices that improve these soil properties.

Objectives: Untitled document
Upon completion of this course the student will be able to:
1.   Collect, prepare, and test a representative soil sample for a variety of crop and forest
      environments and landscape situations.
2.   Compare the functions of the four physical components of soil: air, water, mineral solids,
      organic matter.

      field observations.
4.   Define and cite examples of the five soil-forming factors: parent material, climate,
      topography, living organisms and time.
5.   Distinguish the attributes of the typical horizons within a soil profile.
6.   Relate the importance of soil texture to water holding capacity, aeration, permeability to
      plant roots, and drainage characteristics of soils.
7.   Analyze soil texture using "feel" method and classify soils by percent sand, silt and clay
      content using the soil textural triangle.
8.   Explain the natural processes that result in the formation of soil aggregates and recommend
      practices that enhance or maintain good soil structure.
9.   Summarize the cation exchange process in relation to plant nutrient availability.
10. Describe the sources of soil acidity.
11. Describe harmful effects of pH imbalances and recommend materials and methods for
      managing soil pH.

      supported by the soil food web.
13. Explain the beneficial significance of nitrogen-fixing bacteria and mycorrhizal fungi.
14. Explain mineralization and immobilization of nutrients.
15. Describe the role of soils in the global carbon cycle and select management practices that
      support carbon farming.
16. List the factors that influence decomposition and describe the process of decomposition of
      organic matter.
17. Analyze the nutrient content of synthetic and organic fertilizer materials and predict
      suitability and effectiveness of fertilizers for a variety of crops.
18. Define accelerated erosion by wind and water and describe control methods.
