The Optimization and Validation of the Method for the Determination of Micronutrients in Organic Fertilizers by Inductively Coupled Plasma Optical Emission Spectrometry
Inductively coupled plasma optical emission spectrometry (ICP-OES) analytical method was optimized to determine the micronutrient concentrations from the fertilizers used as inputs in organic farming. The calibration curves showed good linearity for all elements (R2 > 0.999). Recoveries were in t...

Zusammenfassung: | Inductively coupled plasma optical emission spectrometry (ICP-OES) analytical method was optimized to determine the micronutrient concentrations from the fertilizers used as inputs in organic farming. The calibration curves showed good linearity for all elements (R2 > 0.999). Recoveries were in the range of 94.9–97.9%. The values of extended uncertainty with a probability of 95% (k = 2) for the liquid organic fertilizer samples were between 0.004% for Mo and 0.12% for Fe. The results have shown good accuracy and reproducibility, and the optimized method was validated. |
