UC Riverside scientists aim to find how some fungi and bacteria manage to thrive post-wildfires

Scientists have found microbes living in the charred soil that wildfires leave behind. They don't know how some fungi and bacteria manage to thrive when everything else has died, but a new project aims to change that.

Nitrous oxide emissions from agricultural soils contribute to climate change

Poorly drained agricultural soils emit enough of the greenhouse gas nitrous oxide that the resulting climate change effects could far exceed the benefits of using the same soils as a means of sequestering carbon, according to a recently published scientific study.

New study helps figure out how agricultural runoff contributes to global warming

Nitrous oxide (N2O) is a potent greenhouse gas, with 300 times the warming ability of carbon dioxide. Due to fertilizer runoff from farm fields, an increasing load of nitrogen is washing into rivers and streams, where nitrogen-breathing microbes break some of the fertilizer down into N2O, which the river releases into the atmosphere as it tumbles toward the ocean.

Study finds higher levels of air pollutants in regions near oil and gas wells

In a 14-year analysis of air quality across California, Stanford researchers observed higher levels of air pollutants within 2.5 miles of oil and gas wells, likely worsening negative health outcomes for nearby residents.

Exploring sunn hemp and its numerous ecological benefits

Sunn hemp is a superhero in the plant world. And it is a powerful solution to many agricultural challenges related to degradation of natural resources and food security. The October 7th, 2021 Sustainable, Secure Food Blog explores more this plant that can grow in inhospitable environments yet still provide numerous ecological benefits.

UC Riverside scientists aim to turn edible plants into mRNA vaccine factories

The future of vaccines may look more like eating a salad than getting a shot in the arm. UC Riverside scientists are studying whether they can turn edible plants like lettuce into mRNA vaccine factories.

Growing wheat endowed with biological nitrification inhibition raises productivity, quality

An international collaboration has discovered and transferred to elite wheat varieties a wild-grass chromosome segment that causes roots to secrete natural inhibitors of nitrification, offering a way to dial back on heavy fertilizer use for wheat and to reduce the crop's nitrogen leakage into waterways and air, while maintaining or raising its productivity and grain quality, says a new report in the Proceedings of the National Academy of Sciences of the United States of America.

Profound changes in human behavior can meet the challenges of climate emergency

In a year marked by unprecedented flooding, deadly avalanches, and scorching heat waves and wildfires, the climate emergency's enormous cost—whether measured in lost resources or human lives—is all too apparent.

Keeping more nitrogen in soil can minimize environmental damage associated with intensive agriculture

Modern-day agriculture faces two major dilemmas: how to produce enough food to feed the growing human population and how to minimize environmental damage associated with intensive agriculture. Keeping more nitrogen in soil as ammonium may be one key way to address both challenges, according to a new paper in the Proceedings of the National Academy of Sciences (PNAS).

New iron-nitrogen-doped carbon catalyst could reduce harmful air pollutants

Our reliance on fossil fuels as a primary energy source has pushed air pollution to an all-time high, resulting in several environmental and health concerns. Among the major pollutants, nitrogen oxide (NOx) accumulation can cause severe respiratory diseases and imbalance in the Earth's nitrogen cycle. Reducing NOx accumulation is, therefore, an issue of utmost importance.

Climate-smart practices may reduce greenhouse gas emissions from corn production

For corn, using dairy manure and legume cover crops in crop rotations can reduce the need for inorganic nitrogen fertilizer and protect water quality, but these practices also can contribute to emissions of nitrous oxide -- a potent greenhouse gas.

Raising water levels in agricultural peatlands could reduce greenhouse gas emissions

Substantial cuts in global greenhouse gas emissions could be achieved by raising water levels in agricultural peatlands, according to a new study in the journal Nature.

High ozone concentrations decrease crop yield in maize

Although stratospheric ozone protects us by filtering out the sun's ultraviolet radiation, tropospheric ozone is a harmful pollutant. A new study has shown that ozone in the lower layers of the atmosphere decreases crop yields in maize and changes the types of chemicals that are found inside the leaves.

Mycorrhizal fungi can control the emission of N2O from agricultural soil

One of the most significant greenhouse gases that cause global warming is nitrous oxide (N2O).
