The aim of the study was to determine the effect of liming and applying varied doses of sludge (10, 20 and 40 % of fresh mass relative to the weight of soil in a pot) on the content of nitrogen and carbon in plants and in soil, in a four-year pot experiment. Italian ryegrass (Lolium multiflorum) was used as the test plant in the first year, maize and silage sunflower in the second and third years and Italian ryegrass again in the fourth year. The total nitrogen and carbon content was determined in soil samples, taken after each harvest, by the elemental analysis method using a CHN autoanalyser. The nitrogen and carbon content in the test plants cultivated on the soil in limed pots was found to be lower than, or comparable with, those cultiv...
