Question: I didn't get a clear answer previously. I use well water with 20 ppm salt to water the flower beds and potted plants. Over time I know this causes a salt buildup. Will gypsum help to neutralize this salt buildup, or what do I use? I'm not interested in using lime as in the previous answer.
Answer: Sorry the answer wasn't clear! Gypsum improves sodic (saline) soils by
removing sodium from the soil and replacing it with calcium. Use a granular type and spread at the rate of 40 pounds per thousand square feet.
