Leached Nitrate Reduces the Abundance of Antibiotic Resistance Genes in Deep Soil Layers up to 10 mNARA Subscribed
Antibiotic resistance genes (ARGs) represent a threat to human health. Factors impacting ARGs have been well studied in surface soils, but how such factors affect ARGs in deep soils (> 2 m) remains unknown. This in situ study investigated how long‐term excessive nitrogen (N) fertilisation, specifically leached nitrate (NO 3 − ), influenced ARGs up to 10 m depth. Under replicated 26‐year fertilisation (600 kg N ha −1 ) plots, s...
Spartina alterniflora invasion controls organic carbon stocks in coastal marsh and mangrove soils across tropics and subtropicsNARA Subscribed
Coastal wetlands are among the most productive ecosystems and store large amounts of organic carbon (C)—the so termed “blue carbon.” However, wetlands in the tropics and subtropics have been invaded by smooth cordgrass ( Spartina alterniflora ) affecting storage of blue C. To understand how S. alterniflora affects soil organic carbon (SOC) stocks, sources, stability, and their spatial distribution, we sampled soils along a 250...
