Abstract
The ability of Rhizobium leguminosarum by. guar cells to denitrify nitrate in soils under several conditions was tested. All the strains tested were able to remove large amounts of nitrates from soils. Both water filled pore space 40% and temperatures above 20°C greatly increased nitrogen losses. However, even under optimal conditions for denitrifica­tion and the highest rhizobial populations found in agricultural soils, the contribution of Rhizobium to the total denitrification was virtually negli­gible as compared to other soil microorganisms.
