Paper Description
This paper is concerned with the processes and products of soil genesis, models of soil formation, soil classification, the occurrence and spatial variability of soils, and how soils can be mapped using classical and digital techniques including the use of geostatistics, and with methods of land evaluation. Land evaluation is the interpretation of soil and land data in forms applicable to land use planning and management, i.e., the role of pedology in land-use related issues.
The basis of the broad distribution of New Zealand’s soils, and their distinctiveness or otherwise in a global context, are also examined. The basis of the broad distribution of New Zealand’s soils, and their distinctiveness or otherwise in a global context, are also examined
The laboratories 1-5 provide opportunities to engage with a soil-forming process and its impact on soil morphology and other properties (podzolization); quantifying and understanding impact of a selected soil property (nanocrystalline clays and Fe oxides); an exercise to engage with and help understand the “NZ Soil Classification” (NZSC); an exercise to help understand an international soil classification system, “Soil Taxonomy”; and an introduction to the use of GIS in pedology using data related to the evaluation of forestry land in Northland.
One field trip provides an essential core to the paper. The Rotorua trip involves (a) soil stratigraphy and models of pedogenesis in a largely volcanic terrain together with soil characterisation in the field including understanding relationships and useage of genetic horizons, diagnostic horizons, and functional horizons; and (b) application of pedology to understand the science behind the Rotorua Land Treatment System and its effectiveness, as
well as touching on other land use and management including agriculture and forestry, and examining how these relate to specific soil attributes.
Paper Structure
The paper is composed of 23 lectures, five 'dry' laboratories, 5 tutorials, and a one-day field trip.
Lecture 1: Wed 9 am I1.05
Lecture 2: Thu 2 pm KG.06 (new room)
Lecture 3: Fri 12 KG.07 (new room)
Laboratories:
There are 5 labs in total, as listed below.
Tutorials:
These will be held from time to time in the normal lecture time/place as specified in the schedule/timetable.
Field trips:
Rotorua field trip to Mamaku-Rerewhakaaitu-Rotorua will be held in the last week of the August recess on Thursday 29 August (full-day) (precedes the Awakino trip for EARTH312-19B from Friday 30th Aug-Sun 1 Sep).
The field trip is an essential component of the paper and assessment.
The paper is supported by learning resources accessed via Moodle, and printed lecture manual, lab manual, and field trip guide are available for
purchase from the Waikato Print Shop.
Field trip and laboratory exercises are essential. All students must attend and a roll will taken
Learning Outcomes
Students who successfully complete the course should be able to:
Assessment
Requirements for laboratory and field work assignments are provided in the guides. The format of the tests, and pre-test quizzes, will be given at tutorials.
Assessed work consists of (a) Rotorua field trip report, (b) 5 laboratory exercises, (c) test 1, (d) test 2,
and (e) the final exam. Due dates for assessed work are provided in the schedule.
Assessment Components
The internal assessment/exam ratio (as stated in the University Calendar) is 60:40. The final exam makes up 40% of the overall mark.
Required and Recommended Readings
Required Readings
Required texts
Please note that I revise and update lectures each year but the printed lectures in the guide may be modified further during the paper. Consequently, you may need to add or modify material after each lecture (a blank sheet of paper is inserted between each lecture for adding notes if needed).
These texts will be needed:
Study guide for EARTH321-19B (compilation of lectures)
Lab manual for EARTH321-19B
Guidebook for the Rotorua field trip EARTH321-19B
These will be available for purchase from the Waikato Print Shop. You must purchase and bring the lab manual to the first and subsequent labs. Note that the printery 'prints on demand' and so you need to give at least 24 hour notice (i.e. you should order/purchase the lab manual in week 1, well before you need it for the first lab on Tue 16 July). Similarly, the Rotorua field trip guidebook must be ordered/purchased well before the field trip on Thursday 29 Aug (which is near the end of the second week of the Aug recess).
Recommended Readings
- R. Schaetzl & M. Thompson Soils: Genesis and Geomorphology (Cambridge) 2nd edition; one copy has ‘Not for loan’ status in Library.
- D. Milne et al. Soil Description Handbook (Manaaki Whenua Press) revised (2nd) edition.
Other Resources
Class sets
All students will be provided with copies (on loan) of:
- A.E. Hewitt New Zealand Soil Classification 3rd edition
- T.H. Webb and L.R. Lilburne Criteria for Defining the Soil Family and Soil Sibling– the Fourth and Fifth Categories of the NZ Soil Classification
- Soil Survey Staff Keys to Soil Taxonomy
- D.J. Lowe (compiler) Guide to Pedon Description including Clayden and Hewitt Horizon Notation for NZ Soils (in single booklet)
These text books must be returned in good order at the completion of the paper. Failure to return them may result in penalties.
Online Support
Online support will be provided via Moodle, which is accessible to all students who are enrolled in the paper.
Email messages will usually be sent via Moodle. Please note that the email address you provided for Moodle is the one we will use for communication.
Note that the lecture and field trip and laboratory files are subject to copyright and are for use only by students enrolled in this paper in 2019.
Workload
There are 23 lectures, 5 tutorials, a one-day field trip, two tests, and five 2-hour practical (dry lab) sessions.
The workload for each item should relate broadly to the value of the assignment but is largely an individual choice. A 300-level 15 point paper in any of the science subjects offered by the University of Waikato typically involves around 50 hours of supervised study and it is assumed that up to 100 hours will be spent in private study by an ‘average’ student.
