Low-disturbance openers for liquid sidedressing rigs have been available for several years. (A typical style is the coulter/injection nozzle shown on the opposite page.) In contrast, low-disturbance NH3 openers like the ones shown here are a new development. The newest low-disturbance opener for NH3 is the Dawn Model 6000 (top photo) introduced a few months ago. It's the first example of Dawn's modular design concept and offers a lot of flexibility. "The ability to place dry, liquid, and ammonia - orall three at once - at high rates allows the producer to react to volatile fertilizer markets," says Joe Bassett, director of operations at Dawn Equipment (800/554-0007) in Sycamore, Illinois. "This one opener can be used fall, spring, or at sidedressing time at depths up to 7 inches and speeds up to 10 mph."
