Shifts in the Efficiency of ¹⁵N-Ammonium Sulfate Fertilization to Sugarcane Varieties Inoculated with Diazotrophic Bacteria

Agronomy
Nitrogen is an essential plant nutrient, but N fertilization contributes to greenhouse gas emissions through its production and application as well as nitrous oxide emissions when applied to soil.

Snapshots of Coastal Ecology Using Multiproxy Analysis Reveals Insights Into the Preservation of Swamp and Marsh Environments Since the Late Pleistocene

Geochemistry, Geophysics, Geosystems
The southeastern United States Coastal Plain ecosystem contains baldcypress (Taxodium distichum) swamps and grass‐dominated marshes. These ecosystems also occurred on the exposed continental shelf during lower sea levels but are rarely preserved due to ...
