QUESTION: Can salt be composted?
ANSWER: Salt is bad for soil and should generally be left out of compost. However, composting certain foods that have salt in them is fine in moderation, just avoid dumping lots of actual salt into your compost pile.
Tons of foods contain salts and most food products have at least trace amounts of salt in them. Still, the total amount of salt in most products is too low to worry about whether or not to keep them out of the compost heap. As long as you are not composting salt directly, composting salty foods should not cause any problems.
