Postgraduate Course: Soil Science Concepts and Application (PGGE11180)
|School||School of Geosciences
||College||College of Science and Engineering
|Credit level (Normal year taken)||SCQF Level 11 (Postgraduate)
||Availability||Not available to visiting students
|Summary||A soil scientist requires the ability to collect and interpret information on soil physics, biology and chemistry to allow soil preservation and maintenance of soil health. As such, the Soil Science Concepts and Applications module will provide students with a theoretical insight into soil science by looking at the biological, chemical and physical methods of analysis available to scientists, consultants and land managers. This theoretical delivery will be supported by both laboratory and field based practical┐s that allow the students to gain hands on experience in a range of methods, analysis and interpretation.
The aim of the course is to provide students with a more rounded knowledge of soil analytical techniques and experiences. This should improve their potential employability within sectors interested in soil science. Additionally, the laboratory class aspects of the course will provide awareness of good laboratory practice, which should serve as a very transferable skill set as well as improve student readiness for dissertation laboratory and field work.
The course will be delivered over the following 12 teaching periods:
Week 1: Introduction to Soil
a. The heterogeneous nature of soil and biotic/abiotic interactions
b. Soil classification systems and the major soil orders of the world
c. The future of soil science
Week 2: Soil Sampling (lecture and field visit)
a. Sampling strategies and feasibility
b. Qualitative and quantitative determinations
c. Methods of recovery
d. Storage of materials and methods of analysis
Week 3: Soil Physics
a. Soil physical processes and characterisation
b. Measuring soil physical properties
Week 4: Soil Physics (field and lab class)
a. Visual evaluation of soil structure and detecting compaction
b. Sampling for bulk density measurements, soil strength measurements
c. Hand texturing and processing samples collected in the field to determine bulk density and moisture contents
Week 5: Soil Chemistry
a. Importance of soil chemical properties and biogeochemical cycling of elements
b. Methods of analysis for soil nutrients, pH, cation exchange capacity, soil GHG release, soil C and N and dissolved organic C contents
c. Instrumental analysis and handling soil chemical data (units, conversions - liquids, gases and solids, calculating soil stocks)
Week 6: Innovative Learning Week
Week 7: Soil Chemistry (lab class)
a. Soil processing and extraction procedures (water and salt extractions)
b. Measuring soil pH, electrical conductivity and mineral N contents using prepared extracts
c. Extraction of soils for determination of dissolved organic carbon concentrations and analysis (theory)
d. Preparation of soils for determination of C and N contents (theory)
Week 8: Soil Biology
a. Intro to diversity and abundance of organisms in the soil food web
b. Soil biology and sustainable agricultural systems
c. Measuring soil biological properties
Week 9: Soil Biology (lab class)
a. Substrate induced respiration experiment
b. Worm identification session
c. Analysis of greenhouse gases released from soils using gas chromatography (theory)
Week 10: Soil Modelling
a. Introduction to environmental modelling
b. Model optimisation
c. Model validation
Week 11: Soil Modelling (lab class)
a. Overview of IPCC (2019) steady state soil carbon model
b. Overview of soil carbon modelling
c. Conducting a soil carbon modelling assessment for a Scottish livestock farm
Week 12: Scientific report writing/self-study
Teaching staff from within SRUC will deliver the majority of the course content. In some areas expertise from Geosciences at the University of Edinburgh, the Centre for Ecology and Hydrology, the James Hutton Institute, and several local consultants may be utilised to provide collaborative expert support.

|Additional Information (Assessment)
||The course will be assessed by four small laboratory reports and one large scientific report in the style of a journal article. The 2-3 page laboratory reports will be completed in the week following the respective laboratory classes and each will contribute towards 15% of the total award. The results generated from each practical class will then be combined and used to formulate a 3000 word scientific report worth 40% of the total award.
Soil physics lab report (15%):
Soil chemistry lab report (15%):
Soil biology lab report (15%):
Soil modelling report (15%):
Scientific Report (40%):
