Background

The decision to adopt controlled traffic farming (CTF) is a difficult one as it generally involves a significant capital outlay and small reduction in total cropping area. This management strategy aims to alleviate the effects of traffic related soil compaction by restricting machinery movements to designated tramlines. In doing this, farmers are limited to specific types of machinery all based on identical wheel widths. On soil types susceptible to compaction, CTF has the potential to markedly improved yields through improved rooting depth and access to water.
