PLANT SC 7240WT - Soil and Plant Nutrition

Waite Campus - Semester 2 - 2023

The focus of this course is the influence of mineral nutrients to the health of plants. The course will examine the factors that determine the availability of mineral nutrients in soil, their uptake and use by plants. The diagnosis of soil nutrient availability and plant nutrient stress will also be examined. The interaction of mineral nutrients with biotic and abiotic stresses and the role of plant mineral nutrition in human health will also be discussed.

Learning & Teaching Modes

Lectures are used to provide basic information about key concepts and important characteristics of agricultural systems.

Occassional tutorials will be held during the practical period serve to reinforce and extend some of the ideas raised in the lectures and practicals. The aim of these tutorials os to be interactive and to develop skills in topics such as sampling, using diagnostic keys and problem solving

The formal practical classes are used to introduce students to basic ideas related to sampling and diagnosis of plant nutrient status, nutrient uptake, soil-plant interactions.

Students undertake a small independent assignment that uses plant nutrient analysis to identify a nutritional problem or to address a question related to nutrient status of plants, food or beverages.

Additional assignment work requires students to prepare a critical review on a topic which is relevant to their area of study and to develop a case study on a topic related to soil and plant nutrition. These topics change from year to year

Workload

The information below is provided as a guide to assist students in engaging appropriately with the course requirements.

The work load is up to 6 contact hours per week, which will be based on 2 hours of lectures, and up to 4 hours of practical work. There are occassional 1-hour tutorials held during the semester.

It is expected that students will spend an average of approximately 5 hours per week in addition to the formal contact time on assignments, reports and essays.

Each practical runs over a number of weeks

Practical Schedule
1	Soil sampling and analysis for pH, EC and soil P concentrations. The aim of this practical is to provide students with an appreciation of spatial variability in soil properties that influence nutrient availability and uptake as well as the interpretation of soil tests
2	Derivation of a critical level of nitrate in plants: students set up an experiment in two species to examine the response to N. The practical illustrates the general response curve. From severe deficiency to toxicity as well as allows them to derive the critical level for a nutrient.
3	Responses to form and rate of P : Responses to soluble and insoluble forms of P in white lupin, wheat and canola are compared. The experiment demonstrates (a) the effect soil nutrient availability on response to a nutrient, (b) genetic variation in response to a nutrient; (c) nutrient use efficiency
4	Effect of form of N on rhizosphere pH: The practical shows how plants respond to different forms of nutrient and illustrates the root adaptations that maintain nutrient uptake.

Tutorial topics

Assessment Detail

1. Practical reports
Four short reports based on the results of the practical exercises. Using collated class data students are required to use statisitcal analysis to assit witht the interpretation of the results and provide a brief critical analysis of the data.

2. Plant nutrition project
Students working in small groups select a topic that they are interested in and which is related to the application of plant analysis to address a problem or question. They devise a sampling procedure and submit samples for analysis. Students then need to summarise and interpret their results

3. Tutorial questions
There will be a small number of informal tutorials that are integrated into the practicals. This will be involved in diagnosis of nutrient stresses, interpretations of tissue analyses and calculations of nutrient balances.

4. Final exam
A theory exam at the end of the semester s based on material covered in lectures and practicals. Questions include problems realted to intepretation and analysis of data, short answer and extended answer questions.

5. Critical review
This will require students to conduct research into a topic related to a contemporary issue in plant nutrition and provide a critical analysis on the topic. There will be some choice in the topic to allow the student to match it with their background and interest. This will assess the student’s ability to find and critically evaluate information and present this clearly.

6. Case study
Students will be required to complete a detailed case study on an aspect of soil or plant nutrition in an area relevant to their program. The topic will be selected after discussions with the course convenor but it will be based an area covered in lectures.

7. Tutorial questions (0%)
There will be a small number of informal tutorials that are integrated into the practicals. This will be involved in diagnosis of nutrient stresses, interpretations of tissue analyses and calculations of nutrient balances.

Student Feedback

The 最新糖心Vlog places a high priority on approaches to learning and teaching that enhance the student experience. Feedback is sought from students in a variety of ways including on-going engagement with staff, the use of online discussion boards and the use of Student Experience of Learning and Teaching (SELT) surveys as well as GOS surveys and Program reviews.

SELTs are an important source of information to inform individual teaching practice, decisions about teaching duties, and course and program curriculum design. They enable the 最新糖心Vlog to assess how effectively its learning environments and teaching practices facilitate student engagement and learning outcomes. Under the current SELT Policy (http://www.adelaide.edu.au/policies/101/) course SELTs are mandated and must be conducted at the conclusion of each term/semester/trimester for every course offering. Feedback on issues raised through course SELT surveys is made available to enrolled students through various resources (e.g. MyUni). In addition aggregated course SELT data is available.
