Online Amendment Sources:
Where to find amendments in Canada:
  • Local feed stores. Buckerfields is one of them.  Also a commercial outfit called Evergrow in Victoria. Also Integrity Sales in Victoria. There are some stores out here on the West Coast that are more organically oriented and have a better selection (Borden Mercantile in Victoria, for instance). Many of these stores are able to source special products
  • Black Swallow Living Soils (thanks for the link, David!)
  • Alpha chemical resellers may be found on Amazon.ca or ebay.ca

Do you need to use different amendments than those in your OrganiCalc recommendation?  Use our Amendment Converter to find out how much to use.
