Controlled Traffic Farming
At Dale Drills we support the research and demonstration carried out by CTF Europe and Unilever R + D Colworth at Sharnbrook Bedfordshire, into Controlled Traffic Farming. We have supplied a specially adapted 8 meter Dale Zero Till drill with wheels at 3m centres which drills approximately 120 ha each year to demonstrate the advantages which CTF delivers to British soils.
Further information on the work done at Unilever R + D Colworth can be seen at www.controlledtrafficfarming.com.
On all our own cropped land (1200ha) we practice Controlled Traffic Farming. All combining, cultivating if required and drilling is done at 8 meter widths. Wheels are set to the same track settings and as a result wheelings cover approximately 24% of the field area. Before we practiced CTF we would run on 80% to 90% of the field. Although all tyres and combine tracks are set to exert less than 0.7 bar, if we do have a wet time when we have to travel on the field, we know where the soil damage has occurred, and only need to rectify the damage on this area.
CROP ESTABLISHMENT COST COMPARISONS
This bar chart shows the comparison in cost between the different establishment methods. More detailed prices are listed below.

The effect of Controlled Traffic Farming on machinery costs.
Due to the absence of random wheelings across the field, there is no
need for deeper cultivation, except on the headlands where machines have
turned. The soil in CTF also becomes lighter and more easily workable,
enabling a 160hp tractor to comfortably cultivate or drill 40 ha in an
average day, pulling 8m wide equipment.
In the autumn, with 40 available days between 1st August and 31st
October, 800 ha could be cultivated once and a further 800 ha could be
drilled.
In the spring, with 30 available days between 1st February and 30th
April, then a further 600 ha can be cultivated and 600 ha can be
drilled.
Although there is a need to level lift and possibly roll down the
headlands where machinery has turned, which amounts to 15% of the total
area, it would be possible for one 160 hp tractor to do all the landwork
on a 1000ha farm, in controlled traffic farming conditions. In a wet
season another tractor may be required to repair damage in the
controlled wheelings.
Dale Drills used in CTF
As the Eco-Drill works so well in CTF systems, a number have been sold to farmers throughout the uk who use them in such a way. Two cases in particular are Neesham Farms who have used a 9m Eco-Drill in a CTF system since Autumn 2010 and L E Barnes and Son who have used a 12m Eco-Drill in a CTF system since Autumn 2010.
