Aims
To test the hypothesis that over time in controlled traffic farming systems the repeated uneven spreading of header residue back over the tram track width would result in changed soil conditions that would ultimately lead to different “management zones” along the tram track.
Key messages
Although not statistically validated a trend of either higher or lower NDVI’s in the centre of the tram tracks was observed on 7 of the 14 farms investigated.
The trend to wider header fronts makes the practicalities of redistributing residue evenly back across the width of the header all the more difficult and may accelerate any rate of change in crop performance.
In the short term CTF producers should target even redistribution of crop residue across header widths
Further work is needed and the author would welcome collaboration from others in helping to design a future experiment and statistical analysis.

The author acknowledges the support of cooperating farmers in allowing access to both their crops and paddock records. It is hoped that in the future with further work a more definitive result can be found.
