A system for applying fluid to a ground surface, the system includes (a) a plurality of nozzle valves, (b) a control switch and open and close manifold valves for operating each nozzle valve so that each nozzle valve closes essentially concurrently, and (c) a pair of switching manifolds have for operating each nozzle valve so that each nozzle valve is, selectively, opened or closed independently of each other nozzle valve, provided the opened and close valves have not closed the nozzle valves.

[ What is claimed is:] [14.] A system for applying fluid to a ground surface, the system comprising:(a) a plurality of main valves;(b) a plurality of nozzle valves for each main valve;(c) at least one boom, wherein at least one of the main valves and the respective nozzle valves are mounted on the at least one boom;(d) first control means for operating each main valve and each nozzle valve so that each main valve and each respective nozzle valve close essentially concurrently;(e) second control means for operating each nozzle valve so that each nozzle valve is, selectively, opened or closed independently of each other nozzle valve, provided the first control means has not closed the nozzle valves; and,(f) piping means for directing the fluid, the piping means communicating with each main valve and each respective nozzle valve, wherein the fluid is first directed to each main valve, then through each main valve which is open, then to each respective nozzle valve of each main valve which is open, then through each respective nozzle valve which is open, wherein the first control means must operate to open the main valve for the second control means to selectively open each nozzle valve.
