Acid Substitutes and pH Reduction

An evaluation of the new acid-replacement products for improving water quality and the soil rootzone environment.

Given the increase in the use of reclaimed water for irrigation, some turf managers seek alternative acidification products advertised to improve water quality. Materials historically used for industrial cleaning are now being used to acidify irrigation water that contains bicarbonates and sodium. Although the benefits of using traditional acidifying agents such as sulfuric and N-pHuric acid are well known, the implications of using acid-substitute materials is unclear and warrants further investigation.
