Course Description: Evaluates the impact of various soil management practices on soil and water resources. Combines and applies basic information gained in AGRON 502 and AGRON 512. Emphasizes the agronomic, economic, and environmental effects of soil management strategies. Required course for the Master of Science in Agronomy degree program.

Course Prerequisites: AGRON 501, AGRON 503 and AGRON 512. Recommended AGRON 513

Course Overview

The soil is a medium of plant growth with a dynamic natural body composed of minerals, organic matter, water, air, and a community of living organisms including soil microorganisms. Soil properties are therefore classified as physical, chemical and biological. Besides its primary function as a medium of plant growth, the soil provides additional ecological services including air and water purification, climate change (floods and droughts) mitigation, water protection, wastes recycling, biotechnology for human health, and the overall integrity of the environment for ecological sustainability. In agriculture, the goal of soil management is to enhance soil productivity by setting the balance in the physical, chemical and biological properties of the soil. Traditionally, agronomists consider a productive soil as soil that is fertile and provides an environment that supports plant growth. The ability of agronomists to manage the soil to achieve sustainable plant growth is pivotal to modern scientific crop production and food security. The growth of human population and the rapid urbanization of areas for human settlement have limited the availability of productive agricultural land, capable of sustaining food production for food security. Maintaining the ecological integrity of the soil is essential to any policies related to food security for a growing world population. Knowledge of, and the adoption of sound scientific principles for sustainable land and soil management is imperative to achieving the goals of sustainable food production. In recent times, the concept of soil health has become the buzzword for sustainable crop production. A healthy soil is stable, resilient and self-regulating and sustains the integrity of its biological community including the soil microbial population. This course will equip students with knowledge for sustainable soil management by focusing on the principles of soil management in relation to plant nutrient management, the factors, processes, management and impacts of soil erosion, field scale variability of soil properties, including soil water and soil temperature in relation to soil tillage and impacts on sustainable crop production.  

Course Objectives

The course objective is to provide students with the scientific basis to address the impact of management practices on the soil as a medium of plant growth.

At the end of this course, students will be able to:

  • Evaluate the impacts of different soil management practices.
  • Adopt scientific principles to manage the soil.
  • Develop sustainable soil management plans.

Course Structure

The online course materials in Agronomy 532 consists of 13 modules and two exams.

Each module is designed to take one week to complete. Your activities will include the following:

  • Reading the online module material and utilizing the included learning tools.
  • Reading the assigned textbook pages and additional required reading materials.
  • Responding thoughtfully to each Discussion Topic. The Discussion Topics are designed to help you gain perspective on how the concepts in the module might be applied in various situations.
  • Completing and submitting each Module Assignment. The assignments are designed to provide practice with concepts in the modules and, in some cases, to inspire deeper thought.
  • Completing and submitting each Module Reflection. The reflections are designed to help you think about the module concepts as a whole, to consider how module concepts apply to practical applications, and to let me know what is still unclear to you and/or if something has sparked an interest and you want assistance finding resources to learn more about the topic.
  • Asking questions during Office Hours when needed. Not mandatory.

Final Exam 25%

The following grading (with plus/minus grading) will be used to determine course grades:

A's 90% and above
B's 80-89%
C's 70-79%
D's 60-69%
F Below 60%

Final Grades will be assigned on a curve, including +/- grades, which will be developed during the course.

Expectations

Most modules are designed to be completed in one week. The suggested beginning dates are typically on Wednesdays. Your assignments and module reflections will be due about one week after a module's start date, usually the following Tuesday.  Discussion Topic postings are due 7 days after the start of the module and Discussion Summaries are due 2 days after that. See the sections below for additional details.

Assignments 

Assignments are worth 10 or 15 points each. In your answer, quantity is not a substitute for quality and vice versa. We will interact mostly in a written format. Consequently, it is of upmost importance that you express yourself with clarity.

Each assignment  is due by 8 a.m. U.S. Central time, typically the Tuesday following the module's start date. Check the course calendar in Canvas for specifics.

Discussion Topics

Each module contains at least one graded Discussion Topic. Note that some modules contain two or more discussions.

Discussion Topics are worth 10 points. You are required to contribute at least one posting on each discussion topic. Further commenting on classmate postings is strongly encouraged.

Please attempt to post discussion contributions throughout the week. Discussion postings must be completed by the due date to receive participation points. However, subsequent discussion postings are encouraged anytime. Note that some modules have two discussion topics and will have different due dates than other modules. Pay careful attention to the course calendar in Canvas.

The class will be divided into discussion groups of approximately 4 to 6 students per group. The groups will be created based on what we know about your location and work experience. We will attempt to get as much 'experience diversity' in each group as possible. You will receive your discussion group assignment prior to the first discussion.  

Each Discussion Topic must also be summarized for the whole class to view. Discussion Summaries are worth 4 points. You are required to summarize at least one discussion topic throughout the semester. Please work together with your group members to assign responsibility for writing and posting a group discussion summary for each discussion topic. 

Discussion group summaries will be due by 8 a.m. U.S. Central time 2 days following the closure of the discussion for that topic (for example, if the discussion closes at 8 a.m. U.S. Central time on Tuesday, the summary must be posted by 8 a.m. U.S. Central time on Thursday).

Module Reflection

A Module Reflection appears as the last "activity" in each module. The purpose of this activity is to enhance your learning and information retention and to call attention to areas of the course which may need to be revised. Reflection entries are due the same day as module assignments. The reflection is designed to help you reflect on what you have learned and improve your learning style and skills. Each Module Reflection is worth 10 possible points, assigned accordingly with the guidelines described below.

  1. In your own words, write a short summary (<150 words) for this module highlighting and concisely discussing the major concepts of the module (4 points); where appropriate, briefly relate the module's main points to other concepts learned. This can be a great study tool! It will be graded according to the following criteria: 
    Criteria Excellent
    (4 points)
    Good
    (3 points)
    Needs Improvement
    (2 points)
    Unacceptable
    (1 point)

    (10 %)
    Free of writing and spelling errors. Contains very few writing and spelling errors. Contains some writing and spelling errors. Contains many writing and spelling errors.
  2. Value or usefulness of concepts learned (3 points). Connect the information learned to the 'real world' and/or to other information you know.
  3. Unclear items (2.5 points). If anything remains hazy, or you are unsure about some point, please ask! This is another opportunity for you to verify your understanding and to solicit clarification from the instructor. This question also serves to identify those topics that need improved presentation—future classes thank you!
  4. Learning strategies (0.5 point). Tell us about what approaches you use to help yourself learn. Test out and share new strategies. Those that seem to be especially useful or unique will be shared with your classmates, with your permission first. 

Each module reflection is due by 8 a.m. U.S. Central time, on the Tuesday following the module's start date. Pay careful attention to the course calendar in Canvas.

Exams

There will be two exams during the course: a midterm and a final.

The Midterm Exam includes information from Modules 1 through 7, inclusive. The exam may require calculation, deduction, and elaboration and discussion. Expect the exam to be challenging. Points will not be given away! You will earn them. Check the course calendar in Canvas for exam availability.

The Final Exam focuses on material covered in modules 8 through 13, but will rely on concepts covered in modules 1 through 7 as well. Check the course calendar in Canvas for exam availability.
