Effect of supplementary foliar fertilization on maize: A 15 N tracer study
Supplementary foliar nitrogen (N) fertilization at low rates has been explored as an alternative strategy to supply N to field crops when soil application is impractical. However, its effects on maize ( Zea mays L.) yield and fertilizer N recovery remain poorly understood. We conducted a 2‐year field experiment i...
