230 BORON IN SATURATED PASTE EXTRACT
Saturated Paste Extract: B
ICP-AES determination of amount of boron in saturated paste extract.
Summary: This method quantitatively measures the concentration of boron in the extract of the saturated paste. It is based on the determination of boron in the extract using an Inductively Coupled Plasma Atomic Emission Spectrometer (ICP-AES). Plant tolerance to soil boron can be related to the boron concentration in the saturated paste extract. The method has a detection limit of approximately 0.1 mg/L.
