Abstract:

To introduce a conventional method to detect exchangeable Ca and Mg in soil, the inductively coupled plasma spectrometer( ICP-OES) was used as detection means, and ammonium acetate was used as ion-exchange extractant after the exchangeable Ca and Mg in soil samples were obtained by vibrating extraction. The results show that the data of this method have high degree of accuracy, indicating that the method is suitable for the exchangeable Ca and Mg determination in all kinds of soil. At the same time, compared with existing methods, the new method has the advantage of less reagent amount, simple process, and capacity to handle bulk detection.

Key words: Soil, Calcium, Magnesium, Exchanger, Vibration, ICP-OES
