Crop production kept stable and sustainable with the decrease of nitrogen rate in North China Plain: An economic and environmental assessment over 8 years.

ABSTRACT: In pursuit of maximum grain yield farmers in the North China Plain usually apply excessive N fertilizer, resulting in wasted resources and environmental pollution. To assess the economic and environmental performances of different nitrogen rates will be conductive to sustain cleaner crop production. An 8-year field experiment was carried out with four treatments, N0 (0 kg ha^-1 for winter wheat and summer maize), N1 (168 kg ha^-1 for winter wheat and 129 kg ha^-1 for summer maize), N2 (240 kg ha^-1 for winter wheat and 185 kg ha^-1 for summer maize) and N3 (300 kg ha^-1 for winter wheat and summer maize), on the double cropping at Dawenkou research field (36°11'N, 117°06'E), Shandong Province, China.
