Water restrictions and gardens

Huh? I know sod all about Chemistry but even I know Washing Soda is sodium carbonate whereas salt is sodium chloride. Sodium Carbonate (Na2CO3) is a salt. Sodium Chloride (NaCl) is table salt, but there are many other salts. Are all sodiums bad for soil or just in significant quantities or what? I would imagine that Sodium Carbonate would be just as harmful as Sodium Chloride. I attended a greywater workshop a couple of years ago with Ross Mars, and he said that many washing detergents have increased levels of salts to compensate for reduced phosphate levels. He showed us a table showing phosphate and other salts for dozens of brands. Interestingly, the liquid detergents all had low salt levels, so the rule of thumb is to use liquid detergents in preference to powders. |
