ABSTRACT:
An automatically controlled irrigation water pH amendment system and apparatus associated with golf courses utilizing automatic irrigation systems to irrigate the various species of turf grasses used on fairways, tees, greens and other areas; being adapted to receive an operator pre-selected program of desired irrigation water pH value; to monitor the delivered pH value of the irrigation water and automatically blend into the irrigation water in the flow circuit between the discharge of the irrigation pump station pumps and the pH monitoring point the proper amount of chemical additive to amend--raise or lower--the pH of the delivered irrigation water. The desideratum is a uniformly blended mixture of liquid acid or base chemical with irrigation water to maintain a solution of the water pH value desired by the operator to promote proper agronomic practice in the maintenance of the turf grasses. This objective has been found to be obtainable by causing the two liquids to be blended in the proper ratios through the use of an acid tank, pH sensing probe, sulfuric acid injector pumps, acid manifold, booster pump, flow velocity measuring device, and a solid-state electrical programmable controller; connected to the upstream and downstream ports of an ordinary pressure sustaining valve or differential pressure orifice device as used in the discharge line of a golf course pumping station.
