Nitrogen is a critical limiting element for plant growth and production. It is a major component of chlorophyll, the most important pigment needed for photosynthesis, as well as amino acids, the key ...

Nitrogen is essential for all life on Earth. In the global oceans, however, this element is scarce, and nitrogen availability is therefore critical for the growth of marine life. Some bacteria found ...

All known life forms require nitrogen. However, more than 70% of all nitrogen on Earth occurs as inert, triple-bonded dinitrogen gas in the atmosphere, which is generally biologically unavailable. A ...

I was taken back a significant period of years by the article in C&EN on nitrogen fixation as a potential answer to the massive overuse of fertilizers (July 31, 2023, page 24). The underlying reasons ...

Nitrogen is vital for all known life. Yet most nitrogen on Earth is in the atmosphere as di-nitrogen gas, which many organisms can’t use. Fortunately, there are microbes that can tap into this ...

A new research initiative led by associate professor of bacteriology Betül Kaçar is positioned to transform agriculture and address some of the world’s most pressing ecological and economic challenges ...

A new evaluation of biological nitrogen fixation for inland and coastal waters concludes that these habitats are an overlooked but important source of fixation globally. Robinson Fulweiler and ...

Most organisms require nitrogen to produce biological molecules, such as nucleotides and amino acids, but until recently, only prokaryotes were known to fix nitrogen from the atmosphere. “It’s a very ...

A typical day for Jieshun Lin began with a long bus ride to the greenhouses. “For 10 hours each day, I would pull up plants and wash their roots, looking carefully at each individual plant. [Up to] 10 ...

A nifty move with nitrogen has brought the world one step closer to creating a range of useful products — from dyes to pharmaceuticals — out of thin air. The discovery comes from a team of Yale ...

I am often asked, “Can I graze cover crops?” The answer is yes, you can. Sometimes a label we give something pigeonholes it ...

A tiny protein tweak may unlock nitrogen-fixing super-crops that slash global fertilizer demand. Scientists discovered a small protein region that determines whether plants reject or welcome ...
