Experimental Soil Analysis

Course content

The course is organised as a serie of experimental soil analysis exercises in the lab (”hands on”). Based on the students own experimental data, reports including data treatmen will be part of the course. The course is organised as an experimental continuation of the course "Soil, Water and Plants" or equivalent basic soil science course.

The purpose is to train experimental determination of fundamental physical and chemical soil properties of soil, and increase the understanding of processes and properties for soil quality, sustainable plant production and the environment.

Two main parts will be covered during the course: soil physics and soil chemistry.

Soil physics:
Determination of particle size distribution and soil classification. Characterisation and regulation of soil structure. Determination of soil mechanical properties, compaction and soil strength. Characterisation of gas exchange in soil: diffusivity and air permeability.

Water retention properties and soil pore size distribution. Water and air capacity, plant available water. Water movement, water infiltration and soil drainage. Hydraulic conductivity.

Solute transport related to water movement and hydrodynamic dispersion. Leaching of solutes. Thermal properties and heat transport in soil.

Soil chemistry:
Properties for soils classification, sampling and sample conservation of dry and moist soils.

Determination of pH, alkalinity, exchangeable cations, cation exchange capacity (CEC), and base saturation.

Organic carbon, humic acid, organic nitrogen, nitrate, and ammonium. Fractionation of soil phosphate pools. Extraction of iron and aluminium oxides: crystalline and amorphous.

Learning outcome

The aim of the course is fundamental practical training of methods for physical and chemical characterisation of soil in the laboratory, and thereby increase the understanding of properties and processes in soils essential for soil quality, plant production and environment. After completion of the course, the student is expected to be able to:

Knowledge
Experimentally quantify and assess key soil physical and chemical properties of importance for plant growth and environmental protection.
Quantitatively overview of the range of key soil physical and chemical properties common for Danish soil types.
Explain the relationships between land use and physical/chemical soil properties, and vice versa.
Explain fundamental scientific laws, principles, concepts and methods within the course topics.

Skills
Conduct central experimental soil analyses.
Apply and combine trained experimental methods and principles when characterising the soil as a growth medium for plants, and in relation to the risk of pollution of soil and water as consequence of plant production or other land use. 
Apply mathematical mechanistic and statistical models to describe own experimental results, and use the models to predict relevant properties of the soils studied, including critical assessment of limitations to the models applied.  

Competences
Identify and determine essential soil physical and soil chemical aspects of the concept soil quality, interpret experimental results and draw appropriate conclusions.

Lab exercises two days, data treatment and report writing per week in small groups. The teaching is interactive as the teachers usually introduce the theoretical background and the practical conditions for the lab exercise to be conducted. Results are discussed and brought into perspectives in relation to the aim of the course. Training in oral presentation and discussion of key topics is hereby integrated in the exercises.
