FOREST INK: Air current burners are environment friendly wood waste disposal systems

"...Biochar, as a porous carbon substance that retains water, makes nutrients more available thereby strengthening plants in agriculture, gardening and woodlands. It is produced naturally by forest fires (especially large burn piles) and agricultural field burning but relatively little biochar is produced and a lot of smoke pollution also results..."

Scientists come up with new method for simultaneous processing of different types of waste

"...An international research team has come up with an innovative method for metal recovery from industrial waste. The new method allows the simultaneous recovery of multiple metals from waste oxides in a single process. This novel route will lower the burden on waste storage facilities with significant contributions to the economic and environmental sustainability of industrial waste management..."

Kelp for corn? Illinois scientists demystify natural products for crops

"...According to the researchers' classification system, half of the products are live microorganisms, including nitrogen-fixing bacteria, mycorrhizal fungi, phosphorus-solubilizing microbes, or other beneficial microbes. The other half are chemistries or chemical byproducts from "formerly living" organisms, as Sible puts it. These include seaweed extracts, humic and fulvic acids, concentrated enzymes, and biochar..."

Synchrotron aids research into cleaning up mine waste

"...Jon Chorover, a professor and head of the Department of Environmental Science at the University of Arizona, wants to clean up acid mine drainage that contains substantial amounts of heavy metals like arsenic and lead. These top priority pollutants are released when rock materials are exposed to oxygen and rain. The toxic compounds can leak into the ground and contaminate water used for drinking and farming, which can be detrimental to human health..."

FOREST INK: A closer look at our blue grouse family

"...After living on a south-facing Douglas fir forested slope for over four decades we have come to appreciate some of the wildlife species. The mule deer enjoy the addition of shrubs, vegetables and flowers along with some fruit and berry trees which have necessitated the building of fences. We have also appreciated a family of blue grouse that uses the domestic plants as part of their summer food supply..."

Biochar from agricultural waste products can adsorb contaminants in wastewater

"..."Most sewage treatment plants are currently not equipped to remove emerging contaminants such as pharmaceuticals, and if those toxic compounds can be removed by biochars, then wastewater can be recycled in irrigation systems," he said. "That beneficial reuse is critical in regions such as the U. S..."

Biochar helps hold water, saves money: Rice study shows sandy soils benefit most by retaining water, cutting irrigation needs

"...The study co-led by Rice biogeochemist Caroline Masiello and economist Kenneth Medlock provides formulas to help farmers estimate irrigation cost savings from increased water-holding capacity (WHC) with biochar amendment..."

No major phosphorus reductions reported from pilot project

"...A pilot project near Kent Bridge testing absorption materials to prevent phosphorus runoff on farms has not produced major reductions, a virtual panel was told Thursday. Ryan Carlow, soil and water quality technician for the Lower Thames Valley Conservation Authority, presented the results of the project over the last year. During this time, the system was using biochar – a charcoal-like substance – to try to remove phosphorus from the tile drainage on the Roesch Farm..."
