Increasing the Nitrogen Content of Humic Substances in Compost Via Amide Formation Reactions

Abstract / Excerpt:

Humic substances were extracted from compost, and then chemically modified to increase its nitrogen content. The addition of amino groups to the humic substances was attempted using three different synthesis techniques; 1.) thionyl chloride reaction, 2.) aryloxyacetic acid synthesis, and 3.) diethylamine synthesis. The result of chemical analysis showed that the most effective way of increasing the nitrogen in the humic substances is via aryloxyacetic acid synthesis, which showed an increase of 2.10% nitrogen content compared with natural humic substance. In comparison, diethylamine synthesis gave an increase of 1.49% nitrogen content while thionyl chloride reaction lowered the nitrogen content of the natural humic substances.
