An improved mobile agricultural products application system (50) including a multi-variable rate dispensing system (80) particularly adaptable for use in site-specific farming, wherein selected discrete crop input delivery information unique to selected on-board crop input storage device (304), and/or crop input transport systems (70), and/or crop input dispensing points (80) is combined with anticipated field reference point data obtained with a machine positioning system (52, 54), e.g. "Dead Reckoning", GPS, and/or radar, and a computer (14), to direct independent functioning of selected on-board storage devices, material transport systems, crop input release mechanisms and/or dispensing point mechanisms to ensure stored crop inputs are released and combined to vary a prescription of delivered crop inputs in a direction substantially transverse to the direction of machine travel as the crop input applicator machine(s) travels over a predetermined geographic land area. The improved system (50) can selectively and exclusively accommodate precise application of seeds, or can optionally accommodate seed application in combination with other crop inputs.
