title = "Precision nitrogen management strategy for winter wheat in the North China Plain based on an active canopy sensor",
abstract = "The objective of this research was to develop a precision nitrogen (N) management strategy for winter wheat using a Crop Circle ACS-470 sensor and compare it with the GreenSeeker sensorbased precision N management strategy in North China Plain (NCP). Four site-years of field N rate experiments were conducted to investigate the relationships between in-season sensor measurements and yield of winter wheat in Quzhou Experiment station, China. Nine on-farm experiments were conducted at three different villages in Quzhou County in 2012/2013 to evaluate the performance of the N management strategy. Preliminary results indicated that the Crop Circle ACS-470 sensor could significantly improve estimation of early season plant N uptake and grain yield at Feekes growth stage 6 compared with the GreenSeeker sensor. A Crop Circle sensor-based precision N management strategy was proposed, which needs to be evaluated under on-farm conditions.",
