OAGR*2050 Gateway to Organic Agriculture (team taught)
Objectives:

  1. identify the Learning Objectives adopted by this university as common to all undergraduate majors
  2. define and distinguish organic and conventional farming, both in theory and in practice, including the national standards for organic farming
  3. articulate and describe both the scientific principles upon which organic farming is based,
  4. identify the key descriptive features and eco-physiological adaptations of selected grain, forage, and hort crops in organic rotations and common livestock breeds
  5. identify the key social issues in organic agriculture from both a global and local perspective, within the framework of sustainability
  6. identify the major factors affecting the comparative profitability of organic farming and understand the use of value chains to reward on-farm practice

 

CROP*2280 Crops in Land Reclamation
Objectives:

  1. identify the Learning Objectives adopted by this university as common to all undergraduate majors
  2. describe the major types of disturbed land, and for each, the magnitude of land affected in Canada, the degree to which it has been and could be reclaimed, and special problems
  3. discuss the general principles and terminology pertaining to soil (e.g. structure, texture, hydrology, microclimate, chemistry) and other stresses to which plants are exposed to during reclamation of disturbed land
  4. outline the principles and processes of directed ecological succession
  5. distinguish several major plant species used for reclamation, both visually and descriptively
  6. identify several key players in the reclamation industry, including firms, individuals, and associations that are known for their contributions to the field

 

OAGR*3030 Tutorials in Organic Agriculture I (team taught)
Objectives:

  1. inventory a farm to identify strengths, weaknesses, opportunities, and threats (SWOT) for organic farming
  2. take advantage of site diversity by identifying and mapping individual farm management units based on biophysical measures
  3. access appropriate publicly available databases and organizations to identify an economically, ecologically, and socially viable farm enterprise
  4. identify a suitable enterprise for a specific management unit, and prepare a case study/brief justifying the enterprise
  5. estimate a rough nutrient budget for each enterprise, integrating starting soil fertility, realistic yield/animal performance; implied nutrient export; and suitable sources of replacement nutrients
  6. develop a simple enterprise budget showing real world costs for expected inputs to production, processing, and marketing, and real world values for finished products
  7. synthesize recommendations in the form of a case study for each management unit, laying out the parameters that led to the decisions, and identifying potential risks and approaches to managing risk.

OAGR*4160 Design of Organic Production Systems (team taught)
Objectives:

  1. design farm production systems that comply with Canadian organic regulations, acknowledge site-specific biophysical, social, and marketing strengths, weaknesses, opportunities, and threats (SWOT); ‘stack’ enterprises, such that a given resource (e.g. barn, lane, woods, steer, hour of farmer time etc.) earns income from more than one enterprise; capture positive ecological and economic synergies among enterprises, such that each enterprise contributes something to at least one other enterprise, and in turn, benefits from something from another enterprise; and internalize ecological and economic costs of production
  2. view enterprises as multi-functional service providers
  3. identify and use appropriate sources of information to construct a whole farm nutrient budget
  4. prepare a Business Management Plan suitable for soliciting funding from a bank, co-op, or other financial agency

 

Winter Courses

CROP*2110 Crop Ecology
Objectives:

  1. identify the Learning Objectives adopted by this university as common to all undergraduate majors
  2. connect the causal or driving forces underlying agricultural practices, and the rationale for a precautionary approach to technology assessment
  3. explore contemporary issues in crop ecology - such as energy use efficiency - within the context of historical and modern contributions to ecological thought.
  4. analyse the foundational role of system 'design' in the operation of agricultural production systems, and to ponder alternative designs for agriculture in the future
  5. compare biodiversity of natural and managed ecosystems and explain why specific plant and animal species have been domesticated for human nutrition and environmental management, among species and among cultivars or hybrids within crop species, including genetic engineering
  6. relate crop adaptation and management to selected microclimatic and environmental factors, including incident irradiance, photoperiod, air and soil temperature, and the hydrologic cycle.

 

CROP*3340 Managed Grasslands
Objectives:

  1. investigate/explore/acquire information in novel subject areas in a time-efficient manner, organize it logically, and present it effectively in written format
  2. describe the terms and the biological/economic/societal drivers for historic, contemporary, and future use of managed grasslands in Ontario
  3. compare the physiological adaptations conferring tolerance to defoliation frequency and to drought, nutrient, and winter stresses, and to recommend temperate species and mixtures appropriate for diverse situations.
  4. identify the components of forage nutritional value, and quantify the influences of plant species and maturity, the nutritional requirements of animal species and grazing behavior
  5. focus the principles of forage conservation/pasture and grazing management toward practical approaches to resource conservation and livestock production in Ontario
