Efficient use of fertilizer N has become a first-order concern in modern citrus production due to nitrate contamination of ground and surface waters. Excessive N fertilizer rates typically increase N leaching and may also result in ground water contamination (Alva & Paramasivam, 1998; McNeal et al., 1994).
