Join experts Lee McFadyen and Jacques LeCavalier as they explore the benefits and practices of using green manure crops. A green manure crop is any crop grown specifically to be returned to the soil as part of a larger soil building program. Using green manure crops enhances soil fertility by providing a living cover which eventually will be turned into the soil, along with all its biomass and nutrients. This course will explore benefits, techniques, potential limitations, selection, cultivation, and the particulars of various green manure crops. Through a mixture of live-webinars, videos, interactive slideshows, readings, assignments and discussions, this course will actively engage the student, culminating with a test of their knowledge marked by an expert.

  • Students will need a computer or access to the internet
  • Students will need a user account (free, details will be sent by email)
  • Students will need speakers or a headset, as much of this course is given through video lectures

This course is intended for current or prospective farmers. In addition, this course may be suitable if you are:

  • A grower already using organic production methods, and you want to improve your understanding of green manures (particularly as they relate to soil management) and get better at applying them successfully in your operation.
  • Planning to or engaged in the launch of a new organic growing operation.
  • Currently operating a conventional farm and are considering or planning a transition to organic production methods.
  • A current student in an Agricultural Science or related program in a post-secondary learning institution, looking to gain specific knowledge about using green manures.
  • A researcher, consultant or other professional working in agriculture, sustainability or a related field, and you are interested in green manures.
