Denmark
• Overlap 1 – 8 %• 160 tractors with auto steering - 10 cm • 40 tractors with auto steering - 2 cm• ≈ 0,7 % of full time farmers• 3 Farmers do CTF on 1.000 ha.
Danish Agricultural Advisory ServiceNational Centre
Australia
• 200+ farmers do CTF on 1.000.000 ha.• 200+ farmers consider CTF on 1.000.000 ha• 200+ tractors with 2 cm auto steering• 1.000+ tractors with less accurate auto steering• 20-70 % of farmers use auto steering

High accuracy requires own base

Will auto steering companies develop interfaces?

Random traffic is not sustainable
Danish Agricultural Advisory ServiceNational Centre
Controlled traffic farming- sustainable future farming
Danish Agricultural Advisory ServiceNational Centre
Controlled traffic farming- main decisions
• Working width
• Wheel space
• Position of tracks
Danish Agricultural Advisory ServiceNational Centre
Trials with controlled traffic farming
• Grain, Europe: -9 → 21 %(Chamen et.al. 1992)
• Grain, Australia: avg: 16 %(Tullberg et.al 2001)
• Energy used during tillage -70 → -37 %(Chamen et.al. 1992)
• Energy used in total: - 17 %(Dickson & Campbell 1990)
