Golf Course carbonate/alkalinity test

Sonoma County Golf Course
Re : Lab Results from Ionizer System
Period : October 2014 to April 2015

An AG1 unit was installed on the irrigation system at Sonoma County Golf Course in Northern California in October 2014. Below are the “historical” levels of alkalinity and bicarbonate and the recommendations for gypsum per acre foot.

Lab Analysis October 2014
Residual Sodium Carbonate Gypsum per acre foot Total Alkalinity Bicarbonate
2.01 470 lbs. per acre foot  160 ppm 195 ppm
       
Lab Analysis September 2015
Residual Sodium Carbonate Gypsum per acre foot Total Alkalinity Bicarbonate
1.13 264 lbs. per acre foot 118 ppm 144 ppm

 

Residual Sodium Carbonate (RSC) levels
<1.25 = generally safe for irrigation use
1.25 to 2.5 = marginal
>2.5 = Usually unsafe unless treated

 

In This Test:
• RSC levels were reduce from 2.01 to 1.13 taking them from the marginal to generally safe level.
• The course's gypsum use was reduced by 50% going from 470 pounds-per-acre-foot to 264 pounds-per-acre-foot.
• Alkalinity dropped from 160 ppm to 118 ppm.
• Bicarbonate was reduced from 195 ppm to 144 ppm.
