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.

Abstract: A selective liquid fertilizer blending 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 selectively and continuously blend in a "spoon feeding" manner the agronomically correct ratios of liquid fertilizer/irrigation water. The desideratum is a uniformly blended mixture of liquid fertilizer and irrigation water in the agronomically correct spoon-feeding ratios delivered in an aqueous solution to each specific turf grass species used on the separate use areas of the golf course in a continuous manner through sprinkler heads or other irrigation devices.
