Optimizing Management of Alfalfa (<i>Medicago sativa</i> L.) Nitrogen Fertilizer Based on Critical Nitrogen Concentration Dilution Curve Model

Optimizing Management of Alfalfa (<i>Medicago sativa</i> L.) Nitrogen Fertilizer Based on Critical Nitrogen Concentration Dilution Curve Model

The critical nitrogen dilution curve (CNDC) model enables precise nitrogen management by quantifying the threshold of nitrogen deficiency in crops, thereby enhancing both crop productivity and nitrogen use efficiency. However, its applicability to perennial crops remains unclear. In this study, alfa...
