Investigations of the quantity and behaviour of variable positive charges in soils of temperate climatic zone were conducted. The experiments were carried out using sodium forms of clays separated from selected acidic soils of different origin. The clay fractions investigated possess considerable quantities of positive charge connected with mineral components surfaces. It was noted that organic matter presence leads to a considerable decrease of positive charge even when the positive charge observed after organic matter removal was rather high so the organic colloidal particles strongly block the positive charge probably by electrostatic bonds. A linear relationship between iron oxide charge and surface area was obtained.
