Nitrogen use efficiency in high soil-plant nitrogen pool: Fertilizer management optimization via the DNDC model in rice fields
Published 2025-08-01Subjects: “…Soil-plant nitrogen pool…”Enhancing the soil-plant nitrogen (N) pool (SPNP) in paddies system can mitigate environmental N pollution. However, a larger SPNP does not inherently improve N use efficiency (NUE), strategies to enhance NUE under high SPNP remain poorly understood. This study employed the DeNitrification-DeComposi...

Optimized nitrogen application methods to improve nitrogen use efficiency and nodule nitrogen fixation in a maize-soybean relay intercropping system
Published 2018-03-01Subjects: Get full textIn China, the abuse of chemical nitrogen (N) fertilizer results in decreasing N use efficiency (NUE), wasting resources and causing serious environmental problems. Cereal-legume intercropping is widely used to enhance crop yield and improve resource use efficiency, especially in Southwest China. To...

Nitrogen Use Efficiency as Affected by Phosphorus and Potassium in Long-Term Rice and Wheat Experiments
Published 2014-03-01Subjects: “…apparent nitrogen balance…”Improving nitrogen use efficiency (NUE) and decreasing N loss are critical to sustainable agriculture. The objective of this research was to investigate the effect of various fertilization regimes on yield, NUE, N agronomic efficiency (NAE) and N loss in long-term (16- or 24-yr) experiments carried...

Measuring the Sustainability of Nitrogen Fertilization in EU Agriculture: A New Index-Based Assessment in the Context of Sustainable Intensification
Published 2025-07-01Subjects: Get full textThis study comprehensively evaluated nitrogen (N) management in 27 European countries from 1990 to 2021, utilizing the FAO and LUCAS databases. The EU countries were categorized into four groups based on their agricultural production intensities: low (L), medium–low (ML), medium–high (MH), and high...
