CROP*4220 Cropping Systems

course node page

The following description is for the course offering in Winter 2022 and is subject to change. It is provided for information only. The course outline distributed to the class at the beginning of the semester describes the course content and delivery, and defines the methods and criteria to be used in establishing the final grades for the course.
 

Welcome to Cropping Systems! In this course we will learn a version of crop science that takes into account the interplay between i) the management decisions farmers make (individual agency) and ii) the larger structural forces beyond farmer control (e.g. climate, soil type, commodity prices). Together, the interaction between these two variables results in a cropping system. In this course we will analyze the design of cropping systems for specific livestock, poultry and cash crop enterprises. We will discuss the major factors that affect crop yields, quality and economy of production such as choice and interchangeability of crops, crop sequence, tillage, pest control, cover crops, harvesting, drying and storage. The goal of this course is to develop a mental toolkit and habits of mind to assist you in agriculture-related careers.

Learning outcomes:

At the end of this course, students should be able to:
  1. Explain causes of complexity, diversity and dynamics of field crop production systems.
  2. Identify and describe components of crop production, including how these components are organized and optimized into a production system given constraining factors such as climate, soil type, livestock, species adaptation and morphology, and economics.
  3. Analyze how these components and their interactions influence resource use efficiency, crop physiology, soil properties, carbon balances, the nitrogen cycle, water and air quality and identify feedback mechanisms that producers can manipulate to improve system productivity.
  4. Explain how the above production systems concepts are currently utilized in Ontario, as well as systems used in Western Canada, the US Midwest and other developed and developing regions of the world. 
  5. Find accurate and authentic information, synthesize it, and apply it to real-world problems.

Participation in Thursday Discussion's (20%)
In-person discussion-based seminars will occur weekly on Thursdays at 11:30 AM. Seminars will be on Zoom at the start of the semester and move to in-person on-campus once allowed (Room TBD). Seminars will be participatory and based on the asynchronous learning material provided earlier in the week. Specific participatory activities will vary weekly. One example of a participatory activity in the seminar is being randomly assigned to a small 'breakout' group, and as a group develop answers to pre-made discussion questions. We will then reconvene as a class to discuss our answer. This is an individual mark and you will be graded in terms of the quality of your contributions. If you do the assigned readings/watch assigned lectures every week, show up to class, have a couple of thoughtful things to say, and engage respectfully (agreeing or disagreeing) with classmates, you will do absolutely fine. I will let you know in the first month of class if you are doing well or need to improve.
 
Group Discussion Leaders (25%)
Agronomy relies on science as a method of inquiry and as a body of knowledge. However, agronomy also requires a strong understanding of how farms work, an understanding of economics, and practical experience (observing crops and impact of management, etc). As such, we all have something to learn from each other, as this is a group with a diverse skillset and background in crop production. After Reading Week, groups of seven or eight students will begin delivering seminars on relevant topics. The groups, and specific seminar topics, will be decided on the first week of classes based on student interest.
 
Groups will be responsible for developing asynchronous learning materials and leading the on-campus in-person weekly seminar. Prof. Nasielski will provide a 40-50 minute pre-recorded lecture each week covering theory and scientific knowledge of the topic, and will assist each group with seminar delivery and production of materials. Each group will be responsible for the following asynchronous learning materials: one (1) asynchronous pre-recorded lecture (15-20 minutes), one (1) reading of a scientific article, and development of article summary (1 page), and one (1) Q&A with an industry expert (minimum 20 minutes) that can be pre-recorded or done live in the seminar. Groups will also be responsible for leading the weekly seminar and delivering: two or three (2-3) participatory class activities based on the lectures or reading assignments (30-40 minutes each), one (1) Q&A with industry leader (if not pre-recorded).
 
All groups will meet with Prof. Nasielski 4 weeks prior to the seminar date and again 1 week prior to the seminar date to discuss and strategize. More details can be found in the rubric for this assessment. The first five lectures of this course will demonstrate the way these group discussions should be led and the way the types of activities that should be done.
 
This is a group mark, but individual marks can be adjusted if components of the project varied in their quality. While all group members are expected to contribute to as many aspects of the project as possible, very strong or very weak parts of the project will result in changes in individual grades. More information is found in the rubric on CourseLink.
 
Weekly Quiz on CourseLink (20%)
Every week after Thursday's class, an online quiz will be released on CourseLink for you to complete. It will be due Wednesday morning at 10:30 AM. Cognitive science indicates that re-testing yourself on material you've learned over expanding intervals allows you to cheaply and reliably commit huge volumes of information to long-term memory. This is the impetus of weekly tests.
 
In total 10 quizzes will be provided (no quiz on reading week and final week of classes). Each quiz is worth 2.2% of your final grade. Your lowest scoring quiz is dropped when calculating your final grade, so only 9 quizzes are used to calculate final grades.
 
SH** Happens Clause: You can invoke the clause on one quiz at any time before the due date by emailing me. Once invoked, you are granted an immediate 3-day extension on the quiz. No explanation required.
