Revolution the Ground

摘要

From the relative unknowns to the big names, these three precision technologies are helping shape the future of agriculture.NETHERLANDS-BASED WEEDit, which made its debut in 2011, is an optical spot sprayer that's retrofitted on existing sprayers. A relative throwback from the next generation of "green-on-green" precision technologies that distinguish between weeds and crop,the "green-on-brown" WEEDit has made a name for itself through its simple yet effective system utilizing pulse-width modulation (PWM) and flat fan nozzles. If the infrared sensor detects chlorophyll, it will apply chemistry to that plant. The system is most widely used in Australia, where chem fallow periods are long and the payback is quicker.
