Some kind person has dumped two lorry loads of fresh horse manure at the
side of our gates to our allotments, a large grab lorry was seen dropping it
over the fence.
Considering what's going on these days regarding herbicides I wonder if
there is any way to tell if this mountain of manure is contaminated before
some of our gardeners start use it.


yes just put some young tomato plants in it the leaves will react in
hours if there are problems
