We often seem to struggle with controlling the slugs in the middle of the fields,while the 24m headlands seem fine apart from the outside 2m where the slugs come in from the grass margins.It would seem to me that the extra consolidation from turning etc is either killing the blighters or making their life unbearable so they don't consume the rape.So I was thinking of the best way to try and emulate this affect in the middle of the field,we have tried double rolling with paddles with only partial success.Would somthing like a Cultipress post drilling be better? Anyone tried it?
