Yara turns smartphones into nitrogen sensors

摘要

A new innovation from Yara International will allow farmers to measure crop nitrogen requirements using their smartphones.The company launched the new precision farming tool,known as Yaralhx,in March Nitrogen analysis has traditionally required expensive equipment beyond the reach of most growers.Yara's aim in introducing the new tool is to make precision agriculture accessible to all farmers.Yaralrix includes a free-to-download app available for both Android and Apple's iOS.The app uses the smartphone's camera to determine the nitrogen demand of different crops in the early stages of growth.For measuring nitrogen demand during later growth stages,the app requires an additional N-Tester hardware device.This is available as either a smartphone clip-on,or as a separate Bluetooth-enabled device.
