Soil viruses are crucial for microbial life, biogeochemical cycles of carbon and nutrients, and for microbial necromass formation. We hypothesized that the effects of viruses on these processes depend on organic matter and nutrient availability in soils. Here, we combined a 34‐year long‐term fertilization trial, 150 sequenced soil metagenomes, and microcosm experiments to explore how viruses modulate carbon and nutrient dynami...

Increasing soil sodicity represents a critical threat to global agroecosystem health, but how exchangeable sodium percentage (ESP) modulates relationships between biodiversity and ecosystem multifunctionality (BEF) is unresolved. We surveyed 378 soil samples from 189 paired saline–sodic lands and adjacent farmlands across four major saline–sodic regions of China spanning ~2000 km. Random forest models demonstrated that ESP eme...

Aim Soil fauna has a wide range of ecosystem functions. Anthropogenic atmospheric nitrogen (N) deposition affects the structure and function of soil fauna by changing the microenvironment and resources. Given that soil faunal responses can vary considerably among taxonomic groups, N deposition rate, and ecosystems, however, there is little consensus. We aimed to evaluate the effects of N deposition on different soil faunal tax...
