In the paper the results of evaluation effects of liming on the changes agrochemical
soil properties are shown. The experimental part of trial was carried out on the
pseudogley soil of strongly acid reaction and low availability of plant nutrients, during
the three years period. The obtained results show that the use of lime together with the
mineral and organic fertilizers resulted in the decrease of soil acidity for 0.9 pH units in
H2O and 1.0 pH units in KCl. It also increased the phosphorus content for 4.3 mg 100-1
g of soil compared to the control variant, while the potassium content was not significantly
changed. The humus content after the liming was redused by 0.217 % compared to the
control. U radu su prikazani rezultati ispitivanja uticaja kalcizacije na promene
agrohemijskih osobina zemljišta. Eksperimentalni deo ogleda izveden je na
pseudoglejnom zemljištu jako kisele reakcije i slabe obezbeđenosti biljnim hranivima, u
trajanju od tri godine. Dobijeni rezultati pokazuju da je primena krečnog materijala
zajedno sa organskim i mineralnim đubrivom uticala na smanjenje zemljišne kiselosti, i to
za 0,9 pH jedinica u H2O i 1,0 pH jedinica u KCl. Povećan je i sadržaj lakoristupačnog
fosfora za 4,3 mg 100-1 g zemljišta u odnosu na kontrolnu varijantu, dok se sadržaj
kalijuma nije značajnije promenio.
