What approach is being used to separate crops and wheels and to prevent extensive soil damage?

In agriculture, it's essential to minimize soil compaction as it can decrease crop yields and damage the soil structure. One innovative approach being used to prevent extensive soil damage is Controlled Traffic Farming (CTF).

Controlled Traffic Farming is an approach where the crop area and the traffic lanes are permanently separated. In CTF, all machinery is matched to a particular track or gauge width, and the field operations from planting to harvest are conducted on these permanent tracks. This system confines soil compaction to the least possible area of land (about 15-20%), leaving the majority of the soil uncompacted for crop growth.

This system has several benefits: it reduces soil erosion, enhances water absorption, and increases crop yield by reducing soil compaction. Moreover, it also improves efficiency by making field operations more predictable and manageable, thus saving energy, time, and costs.
