INTRODUCTION

The content of water-soluble forms of inorganic cations is one of the substantial characteristics in agrochemical, land reclamation, and sanitary assessments of soils (arable, hayland, pasturable, forest nursery soils). The cation balance should be controlled during ecological soil monitoring for the human activity impact assessment.

The method is used for the determination of the mass concentrationwater-soluble forms of ammonium, potassium, sodium, magnesium and calcium in soils, clays, peats, wastewater silts, activated, sludge, bottom sediments by capillary electrophoresis.
