I'm growing my beans on a patch of land, the only patch I have that is suitable for bean growth. It really is the only suitable bit for the amount of beans I want to grow.
I will be growing beans on them next year as well.
This year, when my beans are over, presumably I do NOT leave the roots in the ground. i know they fix nitrogen in the soil, but if I'm growing beans again, nitrogen in the soil is not what I want, right? Could I feed the roots to the worms in my wormery (that I don't have yet but hopefully will have by the end of summer) so all that lovely nitrogen goes into the vermicompost?
What should I add to the soil to make it ok for growing beans again?
