Can I put soil in compost bin?
I have a tiny back garden lawn (30sqmt), and I want to dig it all out to start over, as it's really bad clay soil. My idea is to dig out the top layer (5cm or do) until the grass roots ends, throw it all out and mix in compost and sand in the remaining soil which I'll loosen up.
I'll first do a small area of maybe 1sqmt to test things out, so I'm wondering if I can just throw out the mix of soil+grass+roots in the compost bin, as I don't want to hire a skip for such a small test area.
Also, any red flags in my plan overall? I don't want to fill 100% of the soil that I dig out, because my soil is already a couple of centimetres above the patio, so when it rains the patio floods before the grass does, so I'll also take the opportunity to lower it all a bit.
