When I took my nursery course I was told that Steer Manure could contain more than 10% salt because they use it at the feed lots to bulk up the cattle. 1 cubic foot of SM is on sale this weekend at $.59. It is being advertised as a fertilizer and has practically no value as fertilizer. It is a great way of adding organic materials to your garden if you can rototill or dig it in and water it enough times to leech the salt out of your soil. If you have clay soils and poor drainage find another organic material. Dave Anderson TLCC http://www.tough-love.com
