AGRONOMY 3012RW - Innovation in Agronomy III

Roseworthy Campus - Semester 2 - 2024

This course aims to provide students with an understanding of the important physiological principles of crop production and how these principles can be applied to cropping systems. The course has three modules focussing on Innovations in: (a) weed management; (b) water and nutrient management; and (c) agronomic management. The first module will focus on enhancing understanding of behaviour of weeds under different tillage systems, herbicide properties and their interaction with crop establishment and weed control in no-till seeding systems. This module will also cover off-target risks of herbicide use including development of herbicide resistance in weeds. The second module will focus on water and nutrient management in cropping systems. Important topics such as managing crop sowing time, cover cropping/rotations and precision planting will be covered. The last module of the course will focus on innovations in crop agronomy including precision agriculture, decision support tool Yield Prophet, grain and graze systems and frost risk and its management. The practical work in this course will focus on learning and applying information from crop simulations models through Yield Prophet, understanding spatial variability from satellite imagery from FluroSat. Another practical will focus on crop safety and weed control with pre-emergence herbicides.

  • Learning & Teaching Activities
    Learning & Teaching Modes
    The course material is taught by a combination of lectures and practical classes, with assessment in the form of practical write-ups, and summative assessment in the form of the final examination. The lectures are organised into three streams. The first of these are lectures that cover major principles related to crop physiology. The second stream covers impact of technological interventions on resource use efficiency. The third stream addresses the role of herbicides and management of herbicide resistance. Lecture modes used are based primarily on traditional classroom paradigms of lecturer-student interactions, using PowerPoint or similar presentation techniques.

    There are four major practicals in this course. First of them deals with developing knowledge of interpreting results from herbicide resistance testing in weed species. Based on data collected for ryegrass samples, students are required to produce individual reports based on the analysis of the data and what it means for the future management of paddocks from where these weed samples were collected. The second practical exercise is based on an online decision support system called Yield Prophet. This is a state of the art decision support system widely used in the Australian grain industry. In this exercise students learn how simulation models are used in the industry to manage nitrogen input for crops. The third practical in this course, develops knowledge of spatial variability in crop growth in cropping fields and how digital platforms are currently used in Australian grains industry to capture and use this information for making management decisions. In this course, we use Regrow/Flurosense which is a relatively new digital platform that uses satellite imagery to capture spatial variability in crop growth within a field. The fourth practical addresses the impact of land use management on important indicators of soil health.

    Feedback is provided on all assessed work.
    Workload

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

    A student enrolled in a 3 unit course, such as this, should expect to spend, on average 12 hours per week on the studies required. This includes both the formal contact time required to the course (e.g., lectures and practicals), as well as non-contact time (e.g., reading and revision).

    The University's policy on Assessment for Coursework Programs is based on the following four principles:

    1. Assessment must encourage and reinforce learning.
    2. Assessment must enable robust and fair judgements about student performance.
    3. Assessment practices must be fair and equitable to students and give them the opportunity to demonstrate what they have learned.
    4. Assessment must maintain academic standards.

    Submission
    Assignments should be submitted with a cover sheet available from MyUni. Feedback will be provided within two weeks after the submission date.

    Late submission of assessments
    If an extension is not applied for, or not granted then a penalty for late submission will apply. A penalty of 10% of the value of the assignment for each calendar day that is late (i.e. weekends count as 2 days), up to a maximum of 50% of the available marks will be applied. This means that an assignment that is 5 days or more late without an approved extension can only receive a maximum of 50% of the mark.
    Course Grading

  • Student Feedback

    The University 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 University 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.

  • Student Support
  • Policies & Guidelines
  • Fraud Awareness

    Students are reminded that in order to maintain the academic integrity of all programs and courses, the university has a zero-tolerance approach to students offering money or significant value goods or services to any staff member who is involved in their teaching or assessment. Students offering lecturers or tutors or professional staff anything more than a small token of appreciation is totally unacceptable, in any circumstances. Staff members are obliged to report all such incidents to their supervisor/manager, who will refer them for action under the university's student’s disciplinary procedures.

The University of Adelaide is committed to regular reviews of the courses and programs it offers to students. The University of Adelaide therefore reserves the right to discontinue or vary programs and courses without notice. Please read the important information contained in the disclaimer.
