Sažetak
In order to examine the residual effect of liming on soil pH and plant available phosphorus and potassium, soil samples from two field trials were analyzed. First trial was conducted in 2000 on Pleternica site where increasing rates of carbocalk (refuse from sugar factory with total Ca content 344 g kg-1) was applied (0, 15, 30, 45, 60 and 90 t ha-1), while soil samples were taken four years after liming. The second trial with 0, 6, 12, 18 and 24 t ha-1 of dolomite containing 56% CaO and 40% MgO was set up at Badljevina locality in 2006 and soil sampling was done in 2009. Liming considerably affected the soil pH in the both trials. Carbocalk gradually raised soil pH from initial very acid to the slightly alkaline reaction, while dolomite application affected pH only at higher rates. Liming increased soil available phosphorus content for 12, 1 mg 100 g-1 four year after carbocalk application and for 8.3 mg 100 g-1 three years after liming with dolomite. Liming with carbocalk significantly decreased potassium availability at 45 t ha-1 and following higher rates, whilst dolomite didn‘t affected potassium content.
