Soil temperature drives nitric oxide emission

Nitric oxide (NO) is a significant contributor to air pollution, and forest soil is a significant source of NO emissions. However, due to a lack of high-frequency NO emission measurements, there are significant uncertainties in global forest soil NO emission. In Northeast China, forest soil...

How to store more carbon in the soil during climate change

Researchers from Cornell University, Ohio State University, Technical University of Munich, and the Connecticut Agricultural Experiment Station are using synchrotron light to study how moisture affects soil carbon - an important ingredient for healthy crops and fertile fields. "Because of climate change, the Earth is warming and humidity events are becoming more dramatic," said Itamar Shabtai, a science assistant at the Connecticut Agricultural...

Study provides methods for obtaining source apportionment of soil heavy metals

Previous studies have indicated that soil heavy metals (HMs) contaminating the surrounding of mining areas mainly emanates from industrial emissions. Research on the quantification of specific risks from various sources is still lacking. Researchers from the Xishuangbanna Tropical Botanical Garden (XTBG) of the Chinese...

Soil analysis finds significant contamination from heavy metals in UK churchyards

Dangerous elements like lead are present in concentrated levels in graveyard soils around UK churches. It presents potentially major problem for surrounding communities and potential redevelopment of sites like this. Scientists used portable X-ray fluorescence techniques to analyse soil in two U.K. churchyards. The sites chosen featured known...

New research reveals cadmium’s route into chocolate

Researchers have chased the source of cacao's cadmium contamination for years. An array of distinct sampling methods and sites led to mixed results. University of Illinois scientists consider the soil factors influencing cadmium's ride into cacao beans. They aimed feasible and cost-effective ways farmers can minimize uptake. Scientists...

Maidenhair trees survived Hiroshima bomb

A "living fossil" is any organism that appeared millions of years ago. That fossil survives today and it is relatively unchanged. The maidenhair tree or Ginkgo biloba, ticks all the boxes of this definition. It is well known in China and Japan. It has special...
