Question of the Week

I'd like to mix more sand into my soil to help break up the clay. If I collect sand from an ocean beach, should I be worried about too much salt in the sand and it impacting my soil? If I were to use the beach sand for another project like a base for setting paving stones, would I be introducing a large amount of sodium?
