Course Number and Title: AGS 101 Soil Science
In this course, students learn elements of soil science and management as they relate to production agriculture, horticulture, and turf sciences.
- Describe soil origins and development with emphasis on parent materials, weathering, and soil formation processes. (CCC 1, 2, 3, 5, 6; PGC LOH 2, 4, 5; PAG 2; TMT 1, 4)
- Explain soil loss by erosion. (CCC 1, 2, 3, 5, 6; PGC LOH 2; PAG 4; TMT 2, 4)
- Describe the role of water in soils, including phases, movement, and measurement. (CCC 1, 2, 3, 5, 6; PGC LOH 2, 5; PAG 3; TMT 1, 2, 3, 4)
- Explain how the organic components of soils influence plant growth. (CCC 1, 2, 3; PGC LOH 2, 5; PAG 3, 4; TMT 2, 4)
- Explain how soil nutrients and power of hydrogen (pH) affect plant growth. (CCC 1, 2, 3, 5; PCG LOH 2, 4, 5; PAG 2, 4; TMT 1, 2, 4)
- Use global positioning system/geographic information systems (GPS/GIS) for applications in agriculture. (CCC 1, 2, 3, 5, 6; PGC LOH 1, 2, 4, 5; PAG 3, 4; TMT 2, 3, 4, 5)
See Core Curriculum Competencies and Program Graduate Competencies at the end of the syllabus. CCPOs are linked to every competency they develop.

- Discuss types of water in soils and related properties of water.
- Discuss water quality and soils.
- Define terms related to water and soils, including adhesion, cohesion, cation exchange capacity, episaturation, endosaturation, percolation, transpiration, and evaporation.
- Discuss the movement of water in soil hydrology.
- Define and discuss the water and nitrogen cycles.
- Discuss soil color and its relationship to water movement.
- Explain how the organic components of soils influence plant growth.
- Define soil organic matter and humus.
- Discuss the composition of organic matter.
- Describe factors affecting the kinds and numbers of organisms in the soil.
- Discuss organic matter maintenance.
- Explain how soil nutrients and power of hydrogen (pH) affect plant growth.
- Describe mineral nutrients specific plants require, what these nutrients do, and how to recognize deficiency symptoms.
- Describe how to control and measure soil pH.
- Explain the importance of soil sampling and soil tests to plant growth and development.
- Use global positioning system/geographic information systems (GPS/GIS) for applications in agriculture.
- Determine when and how to use waypoints to locate specific sites of soil samples.
- Develop attributes for each waypoint marked.
- Prepare a soil site survey map of soil sample locations using GPS/GIS software.
Students must demonstrate proficiency on all CCPOs at a minimal 75 percent level to successfully complete the course. The grade will be determined using the Delaware Tech grading system:
Students should refer to the Student Handbook for information on the Academic Standing Policy, the Academic Integrity Policy, Student Rights and Responsibilities, and other policies relevant to their academic progress.
Calculated using the following weighted average
Percentage of final grade
Exams (2-3) (Summative) (equally weighted)
Final Project (Summative)
Group Presentation (Summative)
Assignments/Activities (Formative) (equally weighted)
Labs (Formative) (equally weighted)
