Medicine Mound,TX | I can't really answer your question because I don't know, but we have worse water. I think the only way we can keep irrigating is because of the sulfates. Our subsoil is gypsum. There are gypsum mines 30 miles west and 30 miles north of me. Our aquifer is very shallow and the water gets really bad towards the end of a season. Was having issues with 28-0-0-5 turning to goo while fertigating and sent the water off. Here is the test. Have had some as high as 3500tds. Very high in NA, Cl, Ca, and SO4.
