ABSTRACT:
A process for making organic slow release nitrogenous fertilizers from pyrolysis products obtained from the pyrolysis of biomass uses a chemical reaction to combine a nitrogen compound containing the --NH.sub.2 group with the pyrolysis products to form a mixture. The mixture is heated to form organic nitrogen compounds. Various sources of biomass can be used. The mixture can be heated to remove water and to cause polymerization and solidification to occur. The mixture can also be combined with an absorbent. Previously, nitrogenous fertilizers had been produced using an ammoxidation process requiring long reaction times of up to several hours.
