Sheep grazing land after pigs

I have a small field which has been grazed constantly by pigs (kunekunes) for the past 5 years and I now wish to move them onto fresh ground. I would like to move some sheep onto the pigs' old field but have been warned that the high copper levels in pig feed get into the grass and can cause copper toxicity in sheep. My pigs have always been fed on Allen and Page pig feed which contains no copper other than that which occurs naturally in the ingredients - should I wait for a while before introducing sheep onto the field and if so, how long might it take for the copper levels to reduce? I keep Soay and Boreray sheep which are highly susceptible to copper poisoning....

You are right about the copper in some pig foods coming through in the pigs faeces and increasing the copper levels in the grass. This is not a danger if there has been no added copper in the diet that has been fed to the pigs so it sounds as though you have nothing to worry about in this instance but I would double check with your food supplier.
Once the copper levels in the soil are elevated they will remain so for years.
