Graduate Degree Programs


Introduction

The Soil Science Department offers several graduate education opportunities to prepare for careers with public and private organizations in soil and environmental sciences. In addition to thesis-based Master of Science and Doctoral programs, two non-thesis Master options are also available for those who prefer to expand their education of soil science without a research emphasis: the Soils option in a Master of Natural Resources is a campus-based program, whereas a Master of Soil Science is available as both a campus-based and a distance education program.

Our average enrollment of 40 graduate students come from a wide range of disciplines. To insure that all are well founded in the discipline of Soil Science, students are expected to acquire competence through course work in the following sub-disciplines (four for Masters and all five for PhD programs): Soil Physics, Soil Chemistry, Soil Microbiology, Soil Genesis and Classification, and Soil Fertility and Plant Nutrition. We also offer advanced soil science graduate courses in analytical methods, chemistry, environmental applications, geomorphology, mineralogy, remote sensing, tropical soils, and wetland soils.

Graduate education in the major sub-disciplines of Soil Science focuses on program areas where our faculty have ongoing multi-disciplinary activities with collaborators in other departments at N.C. State, UNC-Chapel Hill and Duke Universities; State and federal agencies; and private industries. Current research activities among these program areas are described in the following:

Buffers, Water and Air Quality
  • Nutrient contributions from agricultural and forested systems on water quality in watersheds
