Photo gallery: High-speed anhydrous applicatorsJan 17, 2012
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.
