Scientists discover that charcoal traps ammonia pollution

Cornell University scientists Rachel Hestrin and Johannes Lehmann, along with collaborators from Canada and Australia, have shown that charcoal can mop up large quantities of nitrogen from the air pollutant ammonia, resulting ...

Gene network lets plant roots handle nitrogen

With robotics, computers and advanced genetics, researchers at the University of California, Davis and Cold Spring Harbor Laboratory are unraveling how plant roots take up and metabolize nitrogen, the key to plant growth ...

Ammonia synthesis—the greatest innovation of the 20th century

In addition to being a well-known cleaning product, ammonia is essential in the manufacture of fertilizers. The chemical process to synthesize ammonia has hardly changed in 100 years, and is still essential, although scientists ...

Quick soil test aims to determine nitrogen need

Healthy soil contributes to healthy crops. Farmers know this, so they do what they can to ensure their soil is in good shape. They send samples of their soil for lab testing to find out if it is low in any important nutrients. ...
