Variable Rate Irrigation: Worth Another Look

• The number of sprinklers defines how tightly you may want to control a zone as the pivot approaches a region of the field. If you want tighter control, you may use fewer sprinklers in the zone. If it is a big area, you may get by with more sprinklers.
• Set up all of that in the software, then overlay the background image of the field on the grid. Then it's just a matter of the farmer deciding where he wants zero water or any amount between zero and 200 percent of his normal amount of water.
• 100 percent is what a producer puts out at any one time. If he wants a half-inch as his base rate, that becomes the 100 percent. If he wants 30 percent in a zone, then he gets about one-third of that half-inch.
