A major new technology has been developed by The University of Nottingham, which enables all of the world's crops to take nitrogen from the air rather than expensive and environmentally damaging fertilisers.
Nitrogen fixation, the process by which nitrogen
is converted to ammonia
, is vital for plants to survive and grow. However, only a very small number of plants, most notably legumes (such as peas, beans and lentils) have the ability to fix nitrogen from the atmosphere with the help of nitrogen fixing bacteria. The vast majority of plants have to obtain nitrogen from the soil, and for most crops currently being grown across the world, this also means a reliance on synthetic nitrogen fertiliser.

A leading world expert in nitrogen and plant science
, Professor Cocking has long recognised that there is a critical need to reduce nitrogen pollution
caused by nitrogen based fertilisers. Nitrate pollution is a major problem as is also the pollution of the atmosphere by ammonia and oxides of nitrogen.
In addition, nitrate pollution
is a health hazard
and also causes oxygen-depleted 'dead zones' in our waterways and oceans. A recent study estimates that that the annual cost of damage caused by nitrogen pollution across Europe is £60 billion—£280 billion a year.1
