Soil baked to clean up contamination...
Can an old drill site be cleaned up without adding truckloads of contaminated soil to the landfill? Chevron Canada will be using a technology called thermal desorption to clean up a site located 13 kilometres southwest of Pincher Creek. Leif Sollid, spokesman for Chevron, who is the operator of the site, said they considered two options for the clean up. The soil is classified as a non-dangerous waste, but by law it cannot stay as it is. `There`s not a set deadline to clean it up, but we want to ... |

CQESTR simulation of management practice on long-term soil organic carbon
Management of soil organic matter (SOM) is important for soil productivity and responsible utilization of crop residues for additional uses. CQESTR, pronounced `sequester,` a contraction of `C sequestration` (meaning C storage), is a C balance model that relates organic residue additions, crop management, and soil tillage to SOM accretion or loss. Our objective was to simulate SOM changes in agricultural soils under a range of climate and management systems using the CQESTR model. Four long-term ... |
