USGA Summary Points:Proper assessment of irrigation water quality is critical for the golf industry. Current sodicity indices are flawed and likely produce inaccurate estimates of sodicity hazard. After irrigation is applied, the solution concentrates which changes the SAR of the soil water solution. We developed equations for two boundaries (a best case and a worst case scenario) that describe how the SAR is expected to change as the EC of the soil water solution increases. We studied the SAR/EC relationships of several rivers and found that the majority were bounded by the LSAR and ESAR boundaries as the water concentrated. Waters high in alkalinity tended toward the LSAR boundary, while waters low in alkalinity tended toward the ESAR. The LSAR is a simple, accurate, conservative estimate of sodicity hazard and should be favored over all existing sodicity indices in turfgrass management and agricultural production. We developed a spreadsheet that irrigation water laboratories or end users could use to follow our method.
