Abstract
Ammoxidized kraft lignin has been tested as a slow-release fertilizer for the cultivation of sorghum in pot experiments. In comparison to am monium sulfate as a conventional inorganic fertilizer; this modified l ignin was a satisfactory source of nitrogen when applied in high dosag e, producing similar grain and biomass yields as the reference. The so il fertilized with N-functionalized lignin showed essentially lower am ounts of NO3- in the percolation water than soil fertilized with ammon ium sulfate.
