UC Davis researchers found olive trees produce the same yields and high-quality oil when using 25-50% less fertilizer.

Researchers in China have developed an advanced biochar-based material that dramatically improves the removal of harmful nitrate nitrogen from agricultural soils and water, offering promising new avenues for sustainable farming and environmental protection. The study, led by Dr. Lan Luo with colleagues from the Chinese Academy of Agricultural Sciences, explores how biochar loaded with nanoscale zero-valent iron (nZVI) can mitigate nitrogen leaching, a major contributor to groundwater contamination and soil degradation.

From medicine to agriculture and aquaculture, bacteriophages are poised to have a huge global impact. As viruses which target only bacterial cells, they hold promise as an alternative to antibiotics, overcoming increasing issues around antibiotic resistance. However, the size, complexity and growth conditions of phages make them difficult to study, limiting progress in the field. Now in Science Advances, researchers from the Okinawa Institute of Science and Technology (OIST) and University of Otago describe the bacteriophage Bas63 in unprecedented detail, supporting new mechanistic understanding into how these viruses function.

A research team at Hosei University and the University of Tokyo has achieved the world’s first stable production of edamame in an artificial light-type plant factory. Using the NFT hydroponic method, yields surpassed open-field cultivation while enhancing sugar and isoflavone content. This breakthrough enables year-round production of high-quality, nutritious edamame in diverse environments from urban buildings to deserts and even outer space, marking a significant step toward sustainable food systems and healthier diets.

As a mentor, Sindhu Jagadamma, associate professor of soil science at the University of Tennessee Institute of Agriculture, helps her students increase their self-confidence and push themselves to persevere through adversity, traits she learned to improve in herself as a young girl from a small town in India.

Former mentees who worked with Jagadamma in the Sustainable Soil Management Lab nominated her for the Women in Science Mentoring Award, given by the American Society of Agronomy, Crop Science Society of America and Soil Science Society of America. She received the award at the three societies’ annual conference (CANVAS 2025), held November 9-12 in Salt Lake City.
