Wenchao Li from Hebei Agricultural University and Lingling Hua from Beijing University of Agriculture et al. have developed an online monitoring system for NPS pollution in continuous cropping farmland based on a serial pipeline. The system, with diversion trenches, online flowmeters, and dynamic acquisition devices as the core, realizes real-time monitoring and automated sampling of farmland runoff through innovative design. Compared with traditional runoff pools, the design of diversion trenches and transmission pipelines in the new system significantly reduces the project scale, lowers construction costs and land occupation, and avoids interference with agricultural production activities.

From agriculture and urban land clearance to loss of habitat and feral animal predation, native wild animals and their food sources face a rising tide of threats caused by human activities.
A new study led by Flinders University warns traffic noise is one more pressure faced by one of southern Australia’s rare songbirds, the threatened Southern Emu-wren (Stipiturus malachurus).
A groundbreaking approach to turning waste into wealth is set to take center stage in an upcoming international webinar.
Bedding choice is a crucial factor in both cow comfort and udder health, and dairy farms in the Midwest are increasingly turning to recycled manure solids (RMS) as a cost-effective and readily available option. But because RMS originates from manure, questions remain about whether it can harbor mastitis-causing bacteria or other pathogens. A new cross-sectional study in JDS Communications, published by Elsevier, explores how different processing methods affect pathogen levels, giving producers clearer insight into the benefits and limitations of RMS bedding.
A study published in the journal CABI One Health has revealed major inequalities in One Health research.
The new study, which sheds light on global trends in One Health research over the past decade, has found that the volume of research labelled ‘One Health’ has increased exponentially since 2018, and Europe, Asia and Africa have experienced the most marked growth in originating research.
Recently, a review study led by Professor Xuejun Liu from the College of Resources and Environmental Sciences at China Agricultural University and Tianxiang Hao et al. systematically analyzed the current status of China’s farmland carbon budget, providing a scientific solution to this dilemma.
