  1. Soil Respiration of Native Saskatchewan Grassland Calculated from Carbon Dioxide Concentration Profiles

    Schappert, H.J.V.University of Saskatchewan1972

    … to monitor soil respiration by measuring CO2 concentrations in soil throughout the growing season. The technique of gas chromatography was used to obtain CO2 concentration profiles on native grassland and cultivated soils. The CO2 concentration gradients were then used to calculate CO2 …

  2. Root Dynamics, Management Effects and Carbon Sequestration on Invaded and Native Semi-Arid Grasslands

    Balogianni, VasilikiFaculty of Graduate Studies and Research, University of Regina2014

    … cycle through changes in tissue lignin content, CO2 evolution via decomposition, and soil water and C content. Crested wheatgrass had significantly lower root tissue lignin content, higher CO2 evolution from root decomposition, and did not change soil C content. These results suggest that the …

  5. The use of organic materials as amendments in the remediation of soils contaminated by lead, copper and zinc

    Nwachukwu, Olayinka IbiwumiUniversity of Glasgow2007

    … Pb, Cu and Zn toxicity led to an inhibition in CO2 evolved in all amendments, as addition of any amount of Pb, Cu or Zn led to a decrease I amount of CO2 evolved when compared with the non-contaminated amendments. The effect of increasing metal toxicity on CO2 evolution was reflected best in …
