soil biology

National Guard units are conducting training exercises focused on responding to chemical and biological threats. The drill prepares specialized teams to detect and handle hazardous materials in emergency scenarios, part of ongoing efforts to maintain readiness for weapons-of-mass-destruction incidents on US soil.

New reporting suggests soil biology could play a central role in reducing synthetic nitrogen inputs in Canadian winter wheat production. Researchers are examining how soil microbial communities affect nitrogen availability and uptake, with potential benefits for both crop yields and the environmental footprint of fertiliser use. The findings are of interest to farmers and agronomists seeking more sustainable cropping systems.
