Removing the Nitrogen Bottleneck in the World's Food Soupply

Removing the Nitrogen Bottleneck in the World's Food Soupply

By Marc Arakaki

A University of Hawaiʻi at Mānoa researcher is a part of a team that developed a synthetic way to transform nitrogen into a bioavailable form that could allow for the production of ammonia fertilizer at a much lower cost and ultimately lead to greater food production across the globe. Though nitrogen is inexhaustible in the atmosphere, scientists say creating enough bioavailable forms of nitrogen remains one of the most crucial bottlenecks in Earth's ecosystem.

UH Mānoa Department of Chemistry Professor Emeritus Roger Cramer and 13 researchers from universities in Japan have developed a synthetic way to transform nitrogen into a bioavailable form, which only happens naturally during lightning storms and by a type of microorganism called diazotrophs. The research was published in Nature on July 6.

"This research is an essential step toward removing the nitrogen bottleneck on the world's food supply," Cramer said.

Cramer and fellow researchers have discovered a method that uses a synthetic metal-sulfur cluster, and have shown that the  can capture a nitrogen molecule and create a bioavailable form of nitrogen under specific treatment conditions.
