CTF Worldwide

This page aims to identify all those areas in the world where CTF activities are being pursued, and particularly those in commercial use. As this page has only just been launched (2005), it will not yet be extensive in its coverage and that's where you the reader may be able to help. Are you aware of any CTF activities in your geographic region? If you are, just give us a name and contact details if they wish to be included on this page.

World Activities - Further Information

Netherlands

The comparison between conventional and controlled traffic continues on two neighbouring farms growing organic vegetables. CTF increased the yield of spinach harvested mechanically in June 2005 by 15%, and field measurements of N2O (nitrous oxide) emissions showed a reduction in the range 20-50%. The farmers have also reported a reduction in weed pressures due to controlled traffic.

UK

The field demonstration of CTF continues at Unilever in the Uk with support from John Deere and John Dale Drills. The site, on a Hanslope clay soil is in a five-year rotation of wheat, beans, oilseed rape and a spring crop. A module width of 8 m is presently used together with a 2.2 m track gauge on all vehicles other than the harvester which is around 2.7 m. Tramlines for chemical applications are set at 24 m.
