Worms and bad for Soil Biology and Carbon Storage

After a lifetime of being told and thinking that worms are an indicator of healthy soils, I was shocked to read new research out of Canada.

Essentially worms were wiped out in nearly all North America by the last ice age and with the help of introductions by European settlers and the passge of time (worms march forward very slowly from the south of the USA), there are woodlands in Canade with and without earthworms.

Worms are infact very efficient organic matter hoovers. Where they exist there is less Soil Biology as the organic matter they feed on, has been eatern by worms, so there is less Soil Biology.

In addition as there is less organic matter in the soil, less carbon is stored in the soil when worms are present.
