The potential benefits and drawbacks of controlled-traffic farming (CTF), according to Jacob Bolson, an agricultural engineer who researched CTF as a student, include:

*Improved soil structure

*Increased water infiltration and storage

*Increased nutrient-use and moisture-use efficiencies

*Reduced fuel consumption and pesticide costs

*CTF offers a risk-management bonus, by improving soil-moisture retention and use when it’s dry, and by allowing equipment access in the fields even under very wet conditions. CTF growers say they can access their fields when neighbors are bogged down in mud.

 Compacted soil does not hold water; it lacks pores for air, water and plant roots for easy movement in the soil profile. The tracks become compacted and trafficable most of the time.
