CORRELATION BETWEEN STANDARD AND ISOTACHOPHORETIC DETERMINATION OF AVAILABLE NUTRIENTS IN SOILS

Simultaneous determination of numerous available nutrients can be achi eved in one step by means of electromigration methods, including isota chophoresis (ITP). Our goal was to explore the possibilities of access ing both cations and anions in soil by means of capillary isotachophor esis and of showing possible correlations with the standard methods. T he displacement percentages of the respective ions were 17.3 % in Ca2, 20.0 % in Mg2+, 51.4 % in K+, 22.6 % in PO43- and 72.1 % in NO3- com pared with the standards methods.
