  4. Treatments(assigned randomly): well watered (1.2 x ET) mild drought (0.8 x ET) severe drought (0.6 x ET) extra North Experimental layout for 2012 Greenville Farm Single species - 3 water treatments This is an example that matches the program in the manual Multiple species and water treatments can be accommodated 1 12 23 24 13 2 25 3 14 4 15 26 5 26 16 17 6 27 28 18 7 19 8 29 9 20 30 21 10 32 null 22 11 Notes: Once treatments are assigned, the multiplexer and relay driver (SDM-CD16AC) must be rewired in the order of the treatments. For the above example, trees 1,2,6,10,14,15,17,19,21,25,27,&32 are wired into multiplexer 1 channels 1-12; and irrigation valves 1,2,6,10,14,15,17,19,21,25,27,&32 are wired into relay driver 1 channels 1-12. trees 6 and 14 are extra and included in the well watered treatment in this example. They could be assigned to other treatments. Trees 3,4,8,11,16,20,23,26,29 & 30 are wired into multiplexer 1 channels 13-16 & multiplexer 2 channels 1-6; and irrigation valves 3,4,8,11,16,20,23,26,29 & 30 are wired into relay driver 1 channels 13-16 & relay driver 2 channels 1-6. Trees 5,7,9,12,13,18,22,24, 26 & 28 are wired into multiplexer 2 channels 7-16; and irrigation valves 5,7,9,12,13,18,22,24, 26 & 28 are wired into relay driver 2 channels 7-16.
