ABSTRACT
The effect of hard coal fly ash applied on surface of forested (formerly arable) rusty soil on chemical composition of soil surface horizons was evaluated in field experiments conducted between the years 1992-1995. The application of fly ash at the dose 15, 30, 60 and 120 t ha–1
on the soil surface caused a decrease of acidity of soil surface layer which was dependent on the fly ash rate. The deacidification of soil lasted only two years. The application of fly ash increased also the content of macro- and microelements in the soil as well as in Scotch pine needles.
