Core Course Performance Objectives (CCPOs)

  1. 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)
  2. Explain soil loss by erosion. (CCC 1, 2, 3, 5, 6; PGC LOH 2; PAG 4; TMT 2, 4)
  3. 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)
  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)
  5. 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)
  6. 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.

Evaluation Criteria/Policies

The grade will be determined using the Delaware Tech grading system:

90-100 = A
80-89 = B
70-79 = C
0-69 = F
