First time poster here...great resource! Our home was built on land that used to be swampy/marshy until a few years ago. This spring I've noticed an abundance of salt accumulating on the surface, from what I am guessing is due to the high groundwater levels around here. If I was preparing to plant turfgrass, how would I deal with this problem? Replacing the soil with good topsoil/sand wouldn't permanently solve the problem, would it? Wouldn't the salt in the groundwater eventually work it's way through the new layer of soil? Or do I have it wrong and the source could be from somewhere else? Thanks for the help.
