No, it's too risky
- Old metal or wood items may have been painted with lead paint that is
poisonous.
- Fly-tipping often involves nasty items like asbestos that are expensive to
dump legally.
Unless you are feeling very brave I would be inclined to clear away as much
as possible of the solid material (using strong gloves), bag it up and take
it to a council dump. Do this after rain so that there isn't so much dust
to breathe.
Plant flowers only in this area.

A section of my allotment was used as a fly tip and bonfire site. I've
cleared all the rubbish and started to turn the ground over, I'm finding
all
sorts of stuff rusty nail, metal, chipboard and plastic.the soil is a lot
darker with some red lumps which break up when crushed. my question is
should I use this section of ground to grow veg, I was going to plant some
cabbage and kale,or will it contaminant the crop, the allotment is quite
large and there's plenty more ground needs turning over/weeding, so
leaving
some of it wont be too bad.
Thanks
Any advice would be appreciated
