Explain to me how saltwater intrusion affects ponds?

Many crops, especially rice, cannot tolerate any salt. Once the salt water gets in the field the salt binds with the soil and can take years to flush out.

You may have heard of conquering armies salting the land so enemies could not grow crops (Romans and Carthage). Not sure how much crawfish they ate in Carthage…
