I'd like to get an analysis of our soil to see if we are lacking any trace elements. Has anyone found a good provider of this service, and if we do need to supplement, what's the best mineral block/bucket? We're not lambing this year as we've run out of land but I don't want to sell any of the sheep as there's a strong possibility of renting the big field next door in a month or so. So, I need to make sure they're getting maximum nutrition until we can expand their area.
