Is controlled traffic farming altering crop performance across seeder widths in CWFS districts? locations
Aims

To identify any possible impacts on crop growth in controlled traffic systems where the header residue maybe inconsistently spread back across the tram track width over a number of seasons.

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.
