A research team from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences has introduced a soil amendment called humic acid-modified bentonite (HAMB). This amendment effectively enhances a soil’s ability to hold onto ammonium while significantly reducing harmful nitrogen losses. These results were published in the Journal of Soils and Sediments on January 14.
