Hydrochar boosts soil carbon storage and structure more effectively than biochar, study finds

Biochar Editorial Office, Shenyang Agricultural University
Peer-Reviewed Publication

Improving soil health is essential for sustainable agriculture and global food security. A new study reports that hydrochar, a carbon-rich material produced from organic waste, may outperform traditional soil amendments such as biochar and crop residues in strengthening soil structure and storing carbon.

Oregano, rosemary and ‘time’: Long-term swine study shows natural-compound benefits

University of Arkansas System Division of Agriculture
Peer-Reviewed Publication

In a rare long-term public study that compared the effects of phytochemicals from rosemary and oregano with antibiotic growth promoters, animal scientists with the Arkansas Agricultural Experiment Station found that the natural agents given to weaned pigs supported favorable gut health and growth performance later in their lives by preserving microbial diversity to improve nutrient utilization.

Aquaculture is shifting toward less sustainable species: new UBC study

University of British Columbia
Peer-Reviewed Publication

The study, published in Fish and Fisheries, analyzed global aquaculture production from 1950 to 2023 and found that, since the 1980s, the industry has shifted toward a smaller number of intensively farmed species—particularly finfish—that tend to have lower overall sustainability potential.

Hiroshima University
Peer-Reviewed Publication

A review finds that antibiotic resistance genes—capable of undermining modern medicine—can travel through the air across both cities and farmland, and argues that airborne spread represents an overlooked public health risk.
