I am looking for some help in coming up with a list of nitrate scavengers and cover crops that would grow well in extremely shallow, but rich, soil 1–8 inches (about 2.5–20 cm) deep. The soil is set atop asphalt and around several compost bins that occasionally create an excess of leachate. This topic has been explored a bit in one of my recent threads that directly relates to an issue I am having, but I wanted to create a thread that compiles a list of species, something applicable in many other situations; you can read that thread here for context.
There is deeper soil to the rear of the bins, so I have much more flexibility in that area. I am interested in what can grow in the little soil that is more immediately surrounding the bins.
So far, it seems that mint plants and crimson clover might work well.
But what do you think? Do you think any combination of plants might work especially well?
