Sensor-Controlled Fertilizer Spreader

Sensor-Controlled Fertilizer Spreader FERTILIZER APPLICATION Fertilizer Application (58f) 22-4-6 A new dry fertilizer spreader varies the rate of application by "reading" the color of the crop with special sensors that tell the machine how much nutrient the crop needs. Sensors mount on arms off to either side of the machine. They're able to actually determine the amount of chlorophyll content in the leaves. The data goes into a computer which instantly calculates the amount of fertilizer needed. That information runs through electronic controls that vary rate of application on-the-go. The sensor-controlled applicator - designed primarily for spreading nitrogen on growing crops - was a joint effort of four European companies - Amazone-Werke, Massey Ferguson, Dronningborg, and Hydro-Agri.
