Abstract

The accurate determination of available soil O₂ is problematic due to the dynamic interaction of physical and biological soil properties. This study was conducted to evaluate combined effects of soil bulk density, water content, and organic and inorganic amendments on available soil O₂ using CO₂ evolution from soil respiration as an index. Optimal levels of soil aeration vary with respiratory O₂ consumption, which is influenced by soil amendments. Comparisons were made between Pima clay loam [fine-silty, mixed (calcareous), thermic, Typic torrifluvent] amended with inorganic fertilizer or anaerobically digested liquid sewage sludge at equivalent N loading rates. Respiration rates in the inorganic-fertilizer- and sludge-amended soil samples were equivalent.
