1. A sprinkler for watering a selected surface of a land parcel having a selected size and shape, said apparatus comprising: a sprinkler base, said sprinkler base comprising a lower housing defined by a sprinkler base inner side wall, said sprinkler base comprising an inlet for receiving a pressurized water flow, an inlet turbine operably fixed in the base, a gear train having an output gear responsive to the inlet turbine, a mount supported by the base, a stationary cam shaft upwardly affixed from said mount, with at least one cam surface associated with the cam shaft, andan upper housing, said upper housing rotatably coupled to said sprinkler base, said upper housing driven by said output gear, said upper housing configured for receiving water from said base, said upper housing further comprising at least one sprinkler nozzle assembly, said at least one sprinkler nozzle assembly secured to and rotatable with the upper housing, the sprinkler nozzle assembly comprising a nozzle, a spring loaded valve, and a cam follower responsive to said cam surface to adjust the spring loaded valve between an open position wherein water passes therethrough, and a closed position wherein water flow is substantially prevented therethrough. 2. The sprinkler as set forth in claim 1, wherein a plurality of cam surfaces are provided associated with said stationary cam shaft; and wherein a plurality of sprinkler nozzle assemblies are provided, each of said sprinkler nozzle assemblies comprising a nozzle, a spring loaded valve, and a cam follower responsive to one of said plurality of cam surfaces to adjust the spring loaded valve in the sprinkler nozzle assembly between an open position wherein water passes therethrough, and a closed position wherein water flow is substantially prevented therethrough. 3. The sprinkler as set forth in claim 2, wherein said upper housing comprises at least a first side, and wherein a first group of nozzles are provided on the first side. 4. The sprinkler as set forth in claim 3, wherein said upper housing further comprises a second side, and wherein second group of nozzles are provided on the second side. 5. The sprinkler as set forth in claim 2, wherein said upper housing comprises X sides, wherein X is a positive integer, and wherein a group of sprinkler nozzle assemblies is provided on each of said X sides. 6. The sprinkler as set forth in claim 5, wherein each nozzle in said group of sprinkler nozzle assemblies is provided having a selected outlet diameter D, and wherein said selected outlet diameter D varies amongst nozzles in said group of sprinkler nozzle assemblies. 7. The sprinkler as set forth in claim 6, wherein sprinkler nozzle assemblies in each group of sprinkler nozzle assemblies are mounted in a vertical array, one above another. 8. The sprinkler as set forth in claim 7, wherein the outlet diameter D of nozzles in each group of sprinkler nozzle assemblies varies between sprinkler nozzle assemblies in each vertical array. 9. The sprinkler as set forth in claim 8, wherein the outlet diameter D in each group of sprinkler nozzle assemblies varies vertically. 10. The sprinkler as set forth in claim 9, wherein the outlet diameter D in each group of sprinkler nozzle assemblies decreases vertically in an upward direction. 11. The sprinkler as set forth in claim 9, wherein the outlet diameter D in each group of sprinkler nozzle assemblies decreases vertically in a downward direction. 12. The sprinkler as set forth in claim 5, wherein said cam surfaces are each provided by a cam element having a thickness T, and wherein said cam element is detachably affixed to said cam shaft. 13. The sprinkler as set forth in claim 12, further comprising a plurality of retaining clamps, and wherein said cam shaft further comprises pairs of retention grooves, said pairs of retention grooves spaced apart a distance G, said distance G approximately equal to said thickness T, and wherein one retaining clamp in each pair of retaining clamps is secured to said cam shaft below a cam element, and wherein one retaining clamp in each pair of retaining clamps is secured to said cam shaft above a cam element, to thereby secure a cam element at a selected vertical location along said cam shaft. 14. The sprinkler as set forth in claim 13, wherein said cam shaft further comprises an inwardly extending keyway slot, said keyway slot defined by a vertically extending keyway wall. 15. The sprinkler as set forth in claim 13, wherein said cam element comprises an inner sidewall, said inner sidewall further comprising a key structure therein, said key structure sized and shaped for interlocking sliding engagement with said keyway slot in said cam, said key structure and said keyway slot cooperating to prevent said cam element from rotary movement. 16. The sprinkler as set forth in claim 15, wherein each cam element is sized and shaped to provide cam follower movement correlated to water delivery quantity through an associated sprinkler nozzle assembly, for watering a surface of a land parcel having a selected size and shape. 17. The sprinkler as set forth in claim 16, wherein said nozzles N in said sprinkler each have nozzle diameters D selected to deliver water a selected range of radial distances R from said sprinkler, for watering a surface of a land parcel having a selected size and shape. 18. The sprinkler as set forth in claim 17, wherein said nozzles N in said sprinkler each have nozzle diameters D, which in co-operation with said sprinkler nozzle assembly and with said cam element, deliver a selected volume of water along a selected radial for a radial distance R from said sprinkler, for watering a surface of a land parcel having a selected size and shape. 19. The sprinkler as set forth in claim 5, further comprising a generally cylindrical outer housing, said outer housing having an outer diameter OD approximately corresponding to the spacing between distal ends of nozzles in first and second groups of nozzles oriented at one hundred eighty degrees from each other. 20. The sprinkler as set forth in claim 1, wherein said upper housing further comprises an annular gear, and wherein said output gear drives said annular gear, rotating the upper housing rotates. 21. The sprinkler as set forth in claim 1 or in claim 19, further comprising a pressurizable receiver, said pressurizable receiver sized and shaped to receive at least said base therein, vertically house and slidingly cradle said base, wherein upon pressurization by water, said base rises vertically from said pressurizable receiver, to provide a pop-up sprinkler. 22. The sprinkler as set forth in claim 1 or in claim 2, wherein each one of said at least one sprinkler nozzle assembly comprises a cam follower responsive to said cam surface, upon rotation of said cam follower, to adjust the spring loaded valve to regulate the flow of water therethrough by increasing, or by decreasing, or by keeping constant the flow of water therethrough.
