Farm Manure Boosts Greenhouse Gas Emissions -- even in Winter

28th January 2019

Researchers have shown, for the first time, that manure used to fertilize croplands in spring and summer can dramatically increase greenhouse gas emissions in winter. While it's known that farmers' decisions to add nutrients to their fields affects greenhouse gas emissions during the growing season, the study is the first to show that these choices have long-lasting effects, especially as winters warm and soils thaw more frequently.

Forest soils need many decades to recover from fires and logging

24th January 2019

A landmark study from The Australian National University (ANU) has found that forest soils need several decades to recover from bushfires and logging -- much longer than previously thought.

Lead researcher Elle Bowd from the ANU Fenner School of Environment and Society said the team found forest soils recovered very slowly over many years from these events -- up to 80 years following a bushfire and at least 30 years after logging.
