It was found that on average 41.8% to 52.4% of nitrogen in sludge underwent hydrolysis. Yet, it should be stressed that 14.4% to 21.3% of the total amount of nitrogen included bonds characterised by water-soluble fractions, and thus easily accessed by plants.}, type={artykuł}, title={Azot i jego frakcje w komunalnych osadach ściekowych = Nitrogen and its fractions in municipal sawage sludge}, keywords={osady ściekowe, frakcje azotu, sewage sludge, nitrogen fractions}, }
