Miami-Dade County Superintendent Alberto Carvalho announces Miami-Dade schools will be closed on Monday due to Tropical Storm Isaac. MIAMI (CBSMiami) â Miami-Dade County Schools superintendent Alberto Carvalho announced Saturday that all classes have been canceled for Monday, August 27.
Biochar is charcoal used as a soil amendment. Like most charcoal, biochar is created by pyrolysis of biomass. Biochar is under investigation as an approach to carbon sequestration to produce negative carbon dioxide emissions. Biochar thus has the potential to help mitigate climate change, via carbon sequestration.re-Columbian Amazonians are believed to have used biochar to enhance soil productivity. They produced it by smoldering agricultural waste (i.e., covering burning biomass with soil) in pits or trenches. European settlers called it terra preta de Indio.
In addition to creating a soil enhancer, sustainable biochar practices can produce oil and gas byproducts that can be used as fuel, providing clean, renewable energy. When the biochar is buried in the ground as a soil enhancer, the system can become carbon negative..Biochar and bioenergy co-production can help combat global climate change by displacing fossil fuel use and by sequestering carbon in stable soil carbon pools. It may also reduce emissions of nitrous oxide.We can use this simple, yet powerful, technology to reduce carbon emissions.iochar and bioenergy co-production can help combat global climate change by displacing fossil fuel use and by sequestering carbon in stable soil carbon pools.
