The food production sector also contributes to GHG emissions. As a result of bacterial breakdown in soil, farm fields have become a source of nitrogen emissions.  Researchers at NMBU present research showing how new bacteria could reduce agricultural greenhouse gas emissions.

A recent research published by Norwegian scientists focuses on how nitrogen fertilization leads to GHG emissions of nitrous oxide (N2O). This accounts for a significant portion of agriculture’s total greenhouse gas emissions.

Up until now N2O emissions was considered inevitable. But as per a recent research, as nitrous oxide forms in the soil, a new type of bacteria can consume it. This will prevent it from escaping into the atmosphere.

According to the researchers, it is possible to reduce N2O emissions from agriculture by a third in Europe. However, Norway is also showing interest in this research.

For more than 20 years, researchers have been trying to find out how microorganisms in soil convert nitrogen. Researchers also studied how they react to hypoxia, a condition where microbes do not receive enough oxygen.

What Actually Happens?

After fertilization and rainfall, few parts of the soil become hypoxic. Now, there is insufficient supply of oxygen to microbes and they look for other ways to get energy.

Researchers discovered, in such a situation, microbes tend to use nitrate instead of oxygen through denitrification. Through this process, microbes convert nitrate to other gasses, including nitrous oxide. Thus, leading to greenhouse gas emissions.

After gathering in-depth information about this process, researchers found a unique way to study denitrification. Using robotic solutions in the laboratory and field, researchers have developed a special robot to make real-time measurements of nitrous oxide emissions from soil.

Now researchers are working to find out more such types of bacteria and to test them in different soil types of organic waste including fertilizer. After discovering new bacteria could reduce agricultural greenhouse gas emissions, another research project is already underway to find better solutions.
