Soil Science: MS, PhD

Department: Plants, Soils, and Climate Department
College: College of Agriculture and Applied Sciences

Soil Science

USU is the only university in the state that offers degrees in soil science. The graduate programs in soil science are concerned with the chemical, physical, and biological aspects of the soil. This program is particularly strong in water-related issues, especially regional issues involving water and irrigation in the West. In particular, USU boasts unique and renown areas concentrating on digital soil mapping which aids in flood prediction, land restoration, using state-of-the-art environmental sensors to monitor greenhouse gas emissions, and tracking contaminant transport through soils caused by mountain snowmelt.

Students are able to focus their research on solving current issues and problems in areas including soil and water chemistry/biogeochemistry, soil biology and ecology, soils and nutrient bioavailability, environmental soil physics, soil and water management, soil genesis, morphology, and classification, and sustainable agroecosystems. Soil scientists fill the gap between engineers, geologists, and ecologists, and play a major role in ensuring that high-quality soil and water are available to current and future generations.

Admissions Requirements

Students without an undergraduate or graduate degree in plants, soils, biometeorology, or a closely related field may be required to complete selected undergraduate courses prior to admission.

Application Requirements:

  • Complete the online application
  • Pay the $55 application fee
  • Score at or above the 40th percentile on the GRE
  • Have a 3.0 or higher GPA on your last 60 semester or 90 quarter credits
  • Provide transcripts of all college/university credits
  • Provide three contacts for letters of recommendation

International students have additional admissions requirements.

Admissions Deadlines

Applications for graduate programs are accepted year-round. However, chances for acceptance are best if students apply between October and January of each academic year. The time it takes to process an application is primarily dependent on the speed with which the School of Graduate Studies receives letters of recommendation, transcripts, and test scores. For most students, this process may take six to eight weeks. Applicants should plan accordingly.

Master's Degree Plan Option(s)

Students can receive the MS by pursuing one of two options:

  • In the Plan A option, students complete graduate-level coursework and must write a thesis.
  • The Plan B option requires the production of a paper or creative work of art and is expected to reflect equivalent scholarship standards as a thesis.

Students are encouraged to pursue the Plan A option.

Financial Assistance

The department typically funds all of its graduate students with research assistantships.

A variety of additional funding opportunities are available, including fellowships, scholarships, tuition awards, and travel support. Additionally, students may be eligible for subsidized health insurance through qualifying assistantships.
