- 要約等<jats:p>Increased fertilizer N uptake efficiency (FNUE) leads to more economical corn (<jats:italic>Zea mays</jats:italic> L.) production and lower environmental impact. Excessive N application reduces FNUE and may affect subsequen......se through its influence on NO<jats:sub>3</jats:sub>–N carryover and the amount of readily mineralizable organic N in the soil. Our objective was to determine how prior fertilizer N application rate affects (i) grain yield and agronomic optimum N rate, (ii) contributions of fertilizer‐ and soil‐derived N to N uptake, and (iii) FNUE.
