Precision Agriculture Technology Overview

Precision agriculture technology has transformed farming practices with advancements such as GPS guidance, remote sensing, variable rate application, and autonomous vehicles. Adoption rates of technological innovations vary, with some being embraced quickly like herbicide-tolerant crops while others, like the transition from horses/mules to tractors, have been slower. Key technologies include GPS guidance for autosteer and section/row control, yield monitoring with data management, remote sensing with satellite imagery, and variable rate fertilization equipment. Field management zones and application maps play a crucial role in maximizing efficiency and productivity in modern agriculture practices.
