JOHNO, You have been given some sound advice by by Kea, Buster And Saddad.
Any manure you receive at this present time with straw in it MUST be left to rot down till all the straw has disintergrated, it makes no difference wheather it comes from the farmer or the stable next door, the source and the treatment of the straw is still the same. Until what the farmers are spraying and treating straw with is resolved you don,t have options.
I have experienced what affect it has on tomatoes and potatoes and its not good.
To be honest anyone advising you to put it straight on the ground in my opinion is giving you bad advice.
