Study of agricultural watersheds and carbon losses

Dissolved organic carbon (DOC) losses from tile drains are an underquantified portion of the terrestrial carbon cycle. This is particularly important in the eastern corn belt where tile drainage dominates the agricultural ...

Key players in the marine nitrogen cycle use cyanate and urea

The ammonia oxidizing archaea, or Thaumarchaeota, are among the most abundant marine microorganisms. Yet, scientists are still discovering which factors allow them to thrive in the ocean. A research team from the Max Planck ...

Perks of parasitic plants revealed

Parasitic plants, sworn enemy of many a farmer, can carry surprising benefits for wildlife, according to new research.

Tree species composition influences nitrogen loss from forests

Throughout the world, nitrogen compounds are released to the atmosphere from agricultural activities and combustion of fossil fuels. These pollutants are deposited to ecosystems as precipitation, gases, and particles, sometimes ...

Lack of copper in ancient soil regulates nitrification

Researchers from The University of Western Australia and Newcastle University (UK) have discovered copper levels in the soil affect the delicate balance of microbes responsible for soil nitrification, which affects how well ...

Understanding microbial competition for nitrogen

Nitrogen is a hot commodity in the surface ocean. Primary producers including phytoplankton and other microorganisms consume and transform it into organic molecules to build biomass, while others transform inorganic forms ...
