  1. Macro and micro-elements content were measured on pellets of N. lotus leave samples (32 mm diameter × 3 mm thickness) using energy dispersive x-ray fluorescence (ED-XRF) spectroscopy (SPECTRO X-Lab 2000 spectrometer). Measurements were done in triplicate and data presented are expressed in ppm and are mean value ±3σ. The limit of detection for light elements (Si, Al, Mg, and Na) was in the range of 25–50 ppm and 1–5 ppm for heavy metals
