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. This objective has been found to be obtainable by causing the two liquids to be blended in the proper ratios through the use of individual and separate flow circuits contained in a special valve block, there being a separate flow circuit for each separate turf grass species requiring different fertilizer feeding rates; combined with a stratification pressure vessel, an electrical control block, a monthly use inventory storage vessel; 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.
