Lectures and laboratory practicals of chemistry, principles of soil science and MAAT-404 Soil science laboratory I are required prior to attending this course.
After the course the student is able to:
- work independently in soil science laboratory
- plan realistic working schedule
- carry out the most essential laboratory analysis applied for soil samples and understands the theoretical principles of the analytical methods
- independently use the most common analytical instruments needed in soil and plant analytics and understands the principles of the instruments
- calculate the results from raw data and present the results as tables or figures
- use literature references
- present the results in a scientific report
Periodi IV, suositellaan suoritettavaksi 2. lukuvuonna (ympäristötieteiden ja maataloustieteiden kandiohjelmien opiskelijat).
Widening methodological knowledge in soil analytics, independent and systematical working in laboratory. The course covers principles and practice of essential basic methods in soil chemistry and soil physics and laboratory instruments used in those methods. Additionally, writing of a good-quality scientific report based on the analysis results will be practiced.
The analyses carried out on the course:
- Soil bulk and particle density
- Short-range-ordered oxides of Al and Fe
- Soil texture
- Water holding capacity of a soil (pF-curve)
- Soil specific surface area
- Soil mineral nitrogen
- Fixation of K in non-exchangeable form
Lectures 3 h, laboratory exercises 60 h, independent work 72 h.
The exercises are carried out in pairs or in groups within the course period. Before the course the students become familiar with the laboratory manual and set up their own schedules. The teacher will go through the schedule with the students to make sure it is realistic. Before getting started with the laboratory work, participants are also required to hand in preliminary exercises given in advance. A written report of the analyses and the results should be completed within three weeks after finishing the laboratory work. The report is written independently. Final examination can be taken when the report is accepted.

An essential part of the course is a report that consists of introduction to the principles of the analyses, materials and methods of analyses, and the results and their interpretation. Passing the final exam completes the course.
Grading 0–5; lab report 60% and final examination 40%.
If foreign students are enrolled, the language of instruction is English.
