Dribble bar opens way for variable rate application

摘要

Design refinements for the specialist equipment used to apply liquid fertilisers are improving accuracy and rate versatility and making life easier for operators. Peter Hill reports. With the new Auto-Streamer applicator, Billericay Farm Services believes it has achieved the holy grail of liquid fertiliser application - a "dribble bar" with wide-ranging rate capability that can be adjusted without leaving the tractor cab. "With conventional dribble bars and nozzles, scope for rate adjustment is limited," notes BFS general manager, Stephen Kateley. "But with AutoStreamer, operators can go from 60 to 600 litres/ha simply by resetting the sprayer's rate control system."
