Precision agriculture has the capability to reduce excess nitrogen (N) from crop production being released into the environment. This research evaluates the profitability and N use efficiency of utilizing real-time optical sensing with variable-rate technologies (VRT) to manage spatial...

Costs differ among variable rate application systems. Most feasible in Tennessee are the 1-bin and 2-bin spreader beds mounted to existing chassis with an owner-added variable rate controller and global positioning system. Truck spreader systems required more acreage or larger custom charges...

Adoption of precision agriculture technology has arrived considerable attention, but abandonment has received little. This paper identified factors motivating adoption and abandonment of precision soils sampling in cotton. Younger producers who farmed more cotton area, owned more of their...
