Dr. Jonas Baltrusaitis demonstrates sustainable sulfur-based fertilizer engineering in a recent publication

In a paper that appeared in the journal "ACS Sustainable Chemistry and Engineering", Dr. Jonas Baltrusaitis, Assistant Professor of Chemical and Biomolecular Engineering, and his co-workers have demonstrated a novel pathway for synthesizing sustainable sulfur-based fertilizers.

The availability of large elemental sulfur amounts in oil refining and natural gas processing facilities, in combination with the decreasing sulfur deposition into the soil from natural and anthropogenic sources in a bioavailable sulfate form, calls for innovative engineering solutions that bridge this gap via sustainable sulfur processing. Authors devised an adjustable N:S ratio diurea sulfate liquid fertilizers while also successfully obtaining compound granulated N-P-K-S fertilizers.

This work will allow to use currently immobilized large elemental sulfur deposits via their incorporation into the compound fertilizers, which is essential for the plants to efficiently absorb nitrogen.
