<div class="htmlview paragraph">The Cal Poly electrically powered controlled traffic farming (CTF) system was designed to achieve three major objectives: (<span class="xref">1</span>) to reduce soil compaction caused by conventional tractor-based farming practices, (<span class="xref">2</span>) to increase utilization of off-peak power, and (<span class="xref">3</span>) to operate solely under computer control. The CTF system performed all the routine cultural crop-growing activities without putting wheel traffic over the growing field. Field testing was performed to document the operational performance of the CTF system as compared to a conventional wheel-type diesel tractor. Routine field operations were used to determine the extent of soil compaction and the energy consumed by each system.</div>
