The research focused on examining the possibilities of improvement of productive properties of acidic soil (pH 5.4) by applying microbe inocula and CaCO3. First CaCO3 (5 t/ha) was introduced into half of the pots. Then, fifty seeds of red clover were sown into each bottle and 20 ml of inoculum containing rhizobium, azotobacter and actinomycetes in relation 2:1:1 (the number of cells is 10**6 in 1 ml) was added. The control pots were not inoculated. Twenty and forty days after setting the experiment, the length and the dry matter of plant were observed, as well as the number of microorganisms in the soil. Both treatments (inoculation and liming) affected the growth of the plant, but the best effect was achieved when they were combined. The total number of microorganisms and actinomycetes was smaller in the variant without liming. The number of fungi was even in all variants. Twenty days after the treatments, the number of azotobacter was smaller in the variants without liming, whereas forty days later, the number of azotobacter decreased in the variant with liming, too.
