I have a source of dried molasses in 50# bags that are half the price of 50# of sugar... It lists salt in the ingredients, but the guy doesn't think it is much... I have one lawn I would like to jump start with a high dose of molasses this Spring and aerate and compost in May/June as a strategy for dog spot control... Will the salts in the molasses eventually wash away, or dissapate? (The gov't claims that road salt is in the well water, and ditchlines never seem to die or held back in any way from the salts, after the Spring rains...) Should I be concerned???
