Davis >> A previously unrecognized source of nitrogen oxide is contributing up to about 40 percent of the NOx emissions in California, according to a study led by UC Davis.

The study traces the emissions to fertilized soils in the Central Valley.

In the study, published Jan. Both the model and flight data suggested that between 25 and 41 percent of NOx emissions comes from soils with heavy nitrogen fertilizer applications.

Smog forming nitrogen oxides, or NOx, are a family of air polluting chemical compounds. They are central to the formation of ground level ozone and contribute to adverse health effects, such as heart disease, asthma and other respiratory issues.

NOx is a primary component of air pollution, which the World Health Organization estimates causes 1 in 8 deaths worldwide.

Fossil fuels have long been recognized as a major contributor to NOx pollution. Technologies like the catalytic converter have helped greatly reduce NOx emitted from vehicles in urban areas.

But some of the state worst air quality problems are now in rural areas, particularly the San Joaquin Valley, which is home to some of the poorest communities in California.

The Central Valley is also one of the world most highly productive agricultural areas. Roughly half of the fruits and nuts produced in the United States are grown there. This includes nearly all the nation almonds, walnuts, raisins, avocados and tomatoes. need to do it on the land we have. But we need to do it using improved techniques.

Only about half of the nitrogen fertilizer applied to crops is used by the plant. But slow release fertilizers that deliver nutrients in a way that more closely mimics nature have been shown to greatly improve nitrogen use efficiency of crops, reducing emissions of nitrogen in the environment.

Healthy soils programs that restore carbon in the soil can also help fight climate change and are likely to increase nutrient retention and cycling to crops.

And precision agriculture practices help improve water and fertilizer efficiencies, particularly in perennial crops, such as almonds.

The state also began a program this year in which growers work in coalitions to gather information on efficient uses of nitrogen so they can evaluate how and where the state needs to manage nitrogen in agricultural areas. This work aims to reduce nitrate in the groundwater, but it may have a double benefit in reducing NOx emissions. critical that new policies focus on incentives to bring the latest nutrient management technologies to farms so that growers can produce food more efficiently, increasing their bottom line and improving rural health.
