Abstract

The objective of this study was to evaluate the potential benefits of field-specific N management (FSNM) in rain-fed maize farming systems of Northeast China. Two farmer's fields (black and sandy soils) were selected to determine the field-specific optimum N application rates. The results indicated that the optimum N rate was 231 and 224 kg/ha for black soil and sandy soil fields, respectively. The FSNM increased the N use efficiency (NUE) by 7-41 and 5-34% relative to farmer N management (FMNM) for black and sandy soil fields, respectively, while maintaining the corresponding N surplus at about 6 and 59 kg/ha.
