A New Method for Winter Wheat Critical Nitrogen Curve Determination

2013-11-01

Abstract excerpt

As a plant-based N diagnostic tool, critical N curves can be used to adjust the N input in a field according to the crop demand. Because the existing critical N curve determination methods may overestimate the critical N point, making the designed N curve above the actual one, this study presents an improved method to overcome this drawback. An N experiment was conducted during 2 yr (2010–2012) using different win...
