Hi all,
I’m looking for some advice on the use of copper and/or bronze tools.
We’ve been following the no dig approach for approximately 6 months on an existing allotment, but have recently taken on a new allotment that needs some level of initial soil disruption, due to lots of brambles and nettles.
I’ve been reading about the merits of copper tools versus steel, and how the steel in tools leaves a magnetic signature that disorientates slugs and snails, resulting in them finding their way to the crops, whereas copper ones don’t leave any trace. I’m really keen to give copper tools a go but my main concern is that the allotment has historically been worked with steel tools, and I’m not sure how long the ‘steel sugnature’ remains in the soil. Any thoughts on this?

Many thanks in advance,
