AGSC 201 - Basic Soil Science

Credits: 5
LEC hours per week: 4
LAB hours per week: 2
Provides an understanding of soil structure and composition as related to temperature, water, and other environmental controls. Lab work required. Formerly: AGPR 201.
Course Outcomes:
  • Compare and discuss the use and management considerations of unique soils based on physical and chemical characteristics.
  • Classify physical and mineral structural units of soils.
  • Make general land use and fertility recommendations based on organic matter constituents, distribution, and cycling.
  • Estimate and evaluate soil texture using standard methods.
  • Identify types and measurements of soil water and describe how each changes based on soil texture and percent organic matter.
  • Identify common gases in soil and compare them to atmospheric concentrations.
  • Describe cation exchange capacity and how it is influenced by texture, mineralogy, pH, and organic matter.
  • Describe the process of soil formation and development.
  • Predict the physical and chemical characteristics of a soil based on climate, parent materials and mineralogy.
  • Recommend best management practices to reduce soil loss and to increase or maintain site productivity based on a field site assessment inclusive of a soil profile and identification of land capability class for a specific intended use.
