Study Finds Greenhouse Gas Reduction Strategy May Be Safe for Soil Animals

03.06.2011
A new study has found that an emerging tool for combating climate change may cause less harm to some soil animals than initial studies suggested.

Earthworms perform many essential and beneficial functions in the soil ecosystem, including soil structure improvement and nutrient mineralization. However the earthworms’ ability to perform these crucial functions can be suppressed when they are exposed to toxic substances.

A Baylor University geology researcher, along with scientists from Rice University, tested a new soil additive called biochar for its effects on the common earthworm. The researchers found that wetting the biochar before applying it to the soil mitigates the harmful effects of biochar to earthworms and the earthworms’ avoidance of soil with biochar.

“Because of the high potential for widespread application, it is essential to proactively assess and mitigate any unintended consequences associated with biochar soil enrichment,” said study co-author Dr. Bill Hockaday, assistant professor of geology at Baylor. “The results show us that depending on rainfall patterns and irrigation, wetting biochar either before or immediately after soil application would be needed to prevent the disappearance of earthworms and enable their beneficial effects on plants.”

The results appeared on-line in the journal Soil Biology and Biochemistry.

Biochar is of increasing interest because of concerns about climate change caused by emissions of carbon dioxide and other greenhouse gases. It is a byproduct of renewable energy and fuel production from plant materials like forest wastes and crop residues. Biochar is a form of charcoal that enhances soil fertility and plant growth by increasing soil water and nutrient retention, and can store carbon in the soil for hundreds of years.

The researchers found that earthworms avoided soil enriched with dry biochar, and when they were exposed, their weight decreased. After performing several different tests, the researchers found that insufficient moisture was a key factor affecting earthworm behavior in soil enriched with dry biochar. The researchers also found that biochar did not affect earthworm reproduction.

“Most importantly, we are the first to demonstrate that biochar did not stress the immune system of a very sensitive soil organism,” said Dong Li, study co-author and a graduate student at Rice. “This is an important step forward for a very promising strategy in combating climate change.”

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Im Focus: Researchers Imitate Molecular Crowding in Cells

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
