A six-year field experiment involving diluted sulphuric acid treatment
of a sandy soil maintained as bare fallow was carried out. Irrespecti
ve of the experimental variant (0, 0.5, 1.3, and 1.8 acid equivalents
per m(2) per year), neither accumulation of sulphate nor other pronoun
ced changes in the chemical composition of the soil were observed, whe
reas the saturation degree of the cation exchange capacity (5.6 meg/10
0 g soil in the control) decreased in the surface layer from ca. 65-13
%, respectively. After half of plots were sown with grass, the soil un
der grass contained more mineral nitrogen compounds and less organic n
itrogen, compared to bare fallow, irrespective of the soil treatment.
