This paper describes the method of analyzing soil extracts using the Agilent 725-ES Inductively Coupled Plasma-Optical Emission Spectrometer. By analyzing the content of micronutrients in soil samples, the nutrient levels available for plants can be assessed, providing an indication of possible nutrient deficiency. The article describes the analysis of different soil extracts using ICP-OES technique.
The document details a method for analyzing soil samples for available metals such as Zinc, Iron, Manganese, Copper, Sodium, Potassium, Calcium, Magnesium, and Sulfur. It utilizes Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) to assess nutrient levels in agricultural science.
The estimated method detection limit is 15 g/L.
The primary line at 181.972 nm is recommended over the secondary line.
The polychromator can be purged with either argon or nitrogen gas.
