System and method for systematically irrigating subregions of an irrigation region
US-7349763-B2Abstract
A method for irrigating an irrigation region ( 30 ) with an irrigation unit ( 20 ) includes the steps of subdividing the irrigation region ( 30 ) into a plurality of subregions ( 34 ), establishing a sequence for irrigating the subregions ( 34 ) based on irrigation requirements for the irrigation region ( 30 ), and directing a fluid ( 19 ) to one or more of the subregions ( 30 ) using the irrigation unit ( 20 ) based on the sequence. The irrigation regions ( 30 ) can be rectangular, square, or hexagonal, and can each have non-overlapping rectangular, square or triangular, similarly-sized subregions ( 34 ). The irrigation requirements can include the color of the subregions ( 34 ), the elevation of one subregion ( 34 ) relative to another subregion ( 34 ) and/or other physical conditions. The sequence can be established entirely within a housing ( 200 ) of the irrigation unit ( 20 ). The irrigation unit ( 20 ) can direct differing amounts of fluid ( 19 ) per unit of area to the subregions ( 34 ) and/or can direct the fluid ( 19 ) to one subregion ( 34 ) at a time.
