A study in Iceland found that microbes are hoarding more nitrogen for themselves, altering nutrient cycling and leaving less for plants.

Denitrification Looks Different in Rivers Versus Streams
A study directly comparing waterways of different sizes revealed important differences in nitrogen dynamics across seasons.
Microbial Genes Could Improve Our Understanding of Water Pollution
New research in Germany’s Ammer floodplain examines microbial biomarkers to help improve modeling of denitrification.
全球气候模型需要全面纳入氮循环
氮在气候变化、人类健康和农业等领域发挥着重要作用。一位研究人员认为,气候模型若能更全面地纳入氮的影响,将会受益匪浅。
Global Climate Models Need the Nitrogen Cycle—All of It
Nitrogen plays important roles in areas including climate change, human health, and agriculture. A researcher argues that climate models would benefit from more fully incorporating its influence.
A medida que el Ártico se calienta, los suelos pierden nutrientes clave
El cambio climático calienta tanto el aire y el océano, como el suelo, donde los procesos clave que determinan la fertilidad y la captura de carbono operan en un delicado equilibrio.
How Plant-Fungi Friendships Are Changing
A new framework shows how much carbon plants allocate to their endosymbionts and how that amount might change in the face of warming soil and rising carbon dioxide levels.
Shallow Injection Imperfectly Filters Florida Wastewater
Injection of wastewater into shallow wells is meant to filter nutrients like nitrogen and phosphorus out of the wastewater. But a new study suggests that nutrients aren’t entirely eliminated—and may be polluting coastal waters.
Free-Roaming Bison Graze Life into Grasslands
A new study suggests that Yellowstone’s herd of bison accelerates nutrient cycling, offering a glimpse into the North American plains of yesteryear.
Nitrogen Needs Could Be Limiting Nature’s Carbon Capacity
A new study suggests that past calculations of biological nitrogen fixation were overestimated by up to 66%—and that farms growing nitrogen-fixing crops may be filling in the gaps, for better or worse.
