Chemical soil testing data for the ploughed 0-25 cm layer are presented in the paper to make evident the agrochemical evolution of two soil-luvic Brown soils and Albic Luvisols under the influence of long duration liming and fertilization at Livada- Satu Mare agricultural research station during 32 years of field experiments. Through the systematic application of annual fertilisation and periodical liming from 1961 through 1994 basic chemical soil properties substantially improved. The humus content increased 1.50-1.90 times, the degree of base saturation (V) increased by 60 per cent, while the pH (H2O) increased from 4-5 units to 6-8. Correspondingly, the plant available N, P, K, Zn, B contents also increased, while the exchangeable aluminium content diminished to none. As a result of these positive changes in the soil, maize and winter wheat yields increased due to liming and adequate fertilisation from 700 - 1000 kg/ha to 6-7000 kg/ha.
