On succesful completion of this module students should be :-
- technically proficient in the sampling of soils
- technically proficient in soil chemical analysis
- aware of the logistics involved in undertaking soil sampling
- be able to analyse chemical data
- be able to present the results of field/ laboratory work in a technically sound report
To provide students with the knowledge and skills required for the successful sampling of soil and their analysis and interpretation.
1. Laboratory techniques: tools of the trade.
2. Local soil sampling and preliminary preparation and analysis
3. Analysis of macro-nutrients (Na and K) by flame photometry
4. Analysis of macro-nutrients (Mg and Ca) by atomic absorption spectrophotometry
5. Analysis of macro-nutrients (P) by spectrophotometric measurement.
6. Soil pH and gravimetric determination of soil organic matter
7. Walkley-Black technique for soil organic carbon
8. Analysis of trace-elements (e.g. Pb and Zn); analytical quality control
It is assumed (incorrectly) that no student has had any previous experience in laboratory work and the chemical principles involved will be given only a minimal treatment, sufficient to carry out the work and to calculate the results. All students are reminded that the departmental safety regulations MUST be obeyed: adherence to rules, bench tidiness and orderly behaviour are absolute prerequisites for personal safety. For the purposes of safety, ALL students MUST provide themselves with a laboratory coat.
