Influence of Soil Water Content and Bulk Density on Oxygen Diffusion Rate

Akbar Singh Tomar

Abstract

Influence of soil water content and bulk density on oxygen diffusion rate (ODR) of Vertisols was studied in a pot experiment. Significant reduction in ODR was observed with the increase in soil water above 60 per cent of saturation and bulk density above 1.25 Mg m−3. The interaction of water and bulk density (M x B) was also found to be significant.
