Avnv Efficient Technique Removes Ammonia From Agricultural Wastewater
Adding crushed volcanic rock to cropland could play a key role in removing carbon from the air. In a field study, scientists at the University of California, Davis, and Cornell University found the technology stored carbon in the soil even during an extreme drought in California. Thestudywas published in the journal Environmental Research Communications.Rain cap <a href=https://www.nike-dunk.es>nike dunk low</a> tures carbon dioxide from the air as it falls and reacts with volc <a href=https://www.adidas-yeezys.es>nike dunk</a> anic rock to lock up carbon. The process, called rock weathering, can take millions of years ?too slow to offset global warming. But by crushing the rock into a fine dust, rock weathering speeds up. Previousstudieshave estimated this nhanced?rock weathering could store 215 billion tons of carbon dioxide over the next 75 years if spread across croplands globally.But until now the technology hasn been field-tested in dry climates.Wan <a href=https://www.nike-dunk.es>dunk low mujer</a> t more breaking news?Subscribe to Technology Networks?daily newsletter, delivering breaking science news straight to your inbox Indonesia plans to pursue Alphabet Inc's Google for five <a href=https://www.nbbalance.fr>new balance grise</a> years of back taxes, and the search giant could face a bill of more than $400 million for 2015 alone if it is found to have avoided tax payments, a senior tax official told Reuters.Muhammad Hanif, head of the tax office's special cases branch, said its investigators went to Google's local offic <a href=https://www.valela.at>ugg</a> e in Indonesia on Monday.The tax office believes that PT Google Indonesia paid less than 0.1% of the total income and value-added taxes it owed last year.Apple hit with record 13 bn euro Irish tax billMost of the revenue generated in the country is booked at Google's Asia Pacific headquarters in Singapore.
