Q. Why are there no native Canadian earthworms?
A. Because glacial sheets that covered nearly all of Canada until about 15,000 years ago wiped out any native North American species that may have lived here.
Q. Should you try and raise earthworms for the fish bait market?
A. The short answer is "no", but e-mail firstname.lastname@example.org to request package explaining how bait market works.
Q. Should I let earthworm pickers on to my farm to harvest dew worms?
A. You can, and it can be quite profitable for you if you rent out the picking rights. If you are concerned about sustaining the earthworm populations in your field, you could specify the number of nights that can be used by pickers, limit the number of pickers, or have pickers on your land every other year to conserve the worms.
Q. How much should I charge earthworm pickers to harvest earthworms from my farm?
A. That depends on how good your soils are for worms, but a good one-acre field could easily provide 300,000 worms annually which would ultimately retail in the US for $0.20 Canadian each (that's $60,000). I would think that the source farmer should try and obtain about $500 for that.
Q. What is the effect of conservation or no-till on earthworm populations and other soil organisms?
A. They generally increase under conservation or no-till....usually dramatically.
|Till = Conventional tillage|
No-Till = No-Tillage
Q. Will seagulls following the plow destroy earthworm populations in my fields?
A. No. Seagull feeding is normally responsible for far less earthworm mortality than plowing itself.
Q. Do earthworms come to the surface after heavy rains to avoid drowning?
A. No. Earthworms can survive for several weeks under water.
