How soil variability is shaping ag tech

Agriculutral technology companies’ efforts to standardize soil data run up against the reality of complex, living systems

New soil testing and digital agriculture tools are being designed to work with variability as experts say soil complexity can’t be standardized without losing meaning.

New Iridium technology helps block GPS spoofing

New chip can fit into personal devices and farm vehicle systems

A tiny new chip will allow Iridium’s Positioning, Navigation and Timing (PNT) signals to be received much smaller devices, create a security backstop against Global Positioning Systems (GPS) spoofing.

Smoke can be seen rising from near a metal "arm" hanging beneath a machine that has been inserted into a crop by a robotic weeding machine to zap weeds with a laser.

Robots, lasers, and AI, oh my!

Advanced field robotics is transforming agriculture with AI-driven precision, lower labour costs, and reduced soil disturbance.
