Long-term cattle manure application significantly influences soil phosphorus (P) cycling and associated microbial communities in agricultural systems. However, the mechanisms by which P-transforming microbial communities and their ecological networks mediate P cycling and crop productivity under sustained organic amendment remain poorly understood.

The input of fresh carbon can either enhance or suppress the mineralization rate of native soil organic carbon (SOC), a process known as the priming effect. The priming effect plays a crucial role in terrestrial carbon cycling. Although previous studies have attempted to elucidate its mechanisms and responses to nitrogen (N) addition, existing findings remain inconsistent. 

Microbial necromass plays a crucial role in soil organic carbon (SOC) formation, yet the underlying abiotic and biotic factors remain poorly understood, particularly the trophic interactions between protists and fungi/bacteria that drive soil fungal and bacterial necromass accumulation. A groundbreaking 27-year field study reveals that how soil protists differentially control fungal and bacterial necromass accumulation—a key process governing SOC storage. These findings, published in Soil Ecology Letters, redefine our understanding of soil carbon dynamics.

A latest study published in Soil Ecology Letters sheds new light on how mangrove forests adapt to rising salinity levels, a critical threat amplified by climate change. The research, led by Mr. Shamim Ahmed from the Technical University of Munich, demonstrates how soil nutrients and leaf area index (LAI) interact with species and structural diversity to buffer mangrove productivity against salinity stress.

New ultrasound technology developed at Johns Hopkins can distinguish fluid from solid breast masses with near perfect accuracy, an advance that could save patients, especially those with dense breast tissue, from unnecessary follow-up exams, painful procedures and anxiety.

As global populations continue to grow, so does the need for nutritious food and efficient manufacturing processes. Current food production practices generate side streams that could be recycled. Researchers reporting in ACS’ Journal of Agricultural and Food Chemistry fed the side streams of carrot production to fungi, generating a sustainable source of protein. They incorporated the new protein into proof-of-concept vegan patties and sausages that testers ranked as tastier than food made from plant-based proteins.

What if instead of taking a water or soil sample to the lab, you could take the lab to the sample? That’s what a team of researchers reporting in ACS Sensors did with a new nitrate-monitoring “lab-on-a-drone” system. The drone allows for easy, real-time water sampling and analysis in hard-to-reach areas like steep ditches or swampy lowlands. The technology could help farmers optimize their fertilizer use and prevent waterway pollution from excess nitrate runoff.
