Determining the Critical Nitrogen Application Rate for Maximizing Yield While Minimizing NO<sub>3</sub><sup>−</sup>-N Leaching and N<sub>2</sub>O Emissions in Maize Growing on Purple Soil

Optimization of nitrogen (N) fertilizer application is essential to achieve higher crop yields at lower environmental costs. This study investigated the impacts of N application rates (0, 180, and 360 kg N ha<sup>−1</sup>) on maize productivity, N use efficiency (NUE), NO<sub>3<...
