It used to be that growers who wanted to inject anhydrous ammonia in their fields basically had one option. Knives, fitted with nozzles and closing wheels, dug a furrow in the ground about 6 to 8 in. deep and filled it with fertilizer. But recently, some manufacturers have introduced an alternative to this — “high-speed, low-draft” (HSLD) applicators that use single-disc coulters instead of knives to place the fertilizer. The new applicators work at a shallower depth, typically 3 to 5 in. Here is just a sampling of coulter-based anhydrous applicators on the market. Read the related story with further details here.
1. Dawn Anhydra 6000 universal fertilizer applicator
Launched last fall, the Andhydra 6000 universal fertilizer applicator is the industry’s newest coulter-only applicator. It can apply multiple products — anhydrous, granular, liquid or manure — at field speeds as high as 14 mph. Users can set a true gauge wheel from 2 to 6.5 in. deep — only as deep as needed to properly apply product.
Suggested list price: $3,985/row unit or $91,000 for a 23-row unit.

3. Exactrix Mustang P-51 high-speed disc opener
The new Mustang P-51 high-speed single disc opener from Exactrix (pictured) works with the Exactrix high-pressure NH3 injectors, which inject a streaming liquid flow of fertilizer into a narrow slot in the ground.
Suggested list price: At $1,850 each, fits toolbars at 4 x 4, 6 x 6 or 7 x 7.

5. John Deere 2510H nutrient applicator
The new 23-row 2510H nutrient applicator from John Deere is a larger unit than the applicator launched in 2008, so growers can cover more ground in less time. A single disc opener is used to place anhydrous.
Suggested list price: around $97,000.

6. Case IH Nutri-Placer 940
Case IH is staying with a knife-based fertilizer applicator, the Nutri-Placer 940, for now until more studies are done to prove the sealing ability of coulter-only machines. The anhydrous applicator is the widest in the industry at 65 ft.
Suggested list price: $102,000 for 65-ft. model.
