I live in the northern part of the province and I give talks to people about composting. It is almost inevitable that someone will comment that they have an area of their yard that has lots of worms, but the soil is very hard. Many of these people are of the opinion that it is the worms that makes the soil hard. I believe the worms aren't responsible, but that is really just a guess, and I tell them to add plenty of compost and other organic matter. Is anyone familiar with this situation?
