ABSTRACT
It was studied the effect of some anionic polyelectrolytes from maleic acid ammonium salt copolymers or terpolymers with vinyl acetate, methyl methacrylate or styrene on the structure of Cambic Chernozem soil Fundulea, Romania. This effect is determined by the chemical structure of the polyelectrolyte (the nature of comonomer(s)) and its concentration, the aggregate size being less important.
