Answer:

adding denitrifying bacteria to the soil

Explanation:

Denitrifying bacteria refer to microorganisms in soil that carry out the conversion of nitrates in soil to free atmospheric nitrogen.

Nitrogen gas (N2) is ultimately the product of denitrification of soil, however certain intermediate nitrogen species are also formed in the process. Some of these intermediates may include the following sequence of conversion; NO3− → NO2−→ NO + N2O → N2.

The chemical equation for denitrification is; 2 NO3− + 10 e− + 12 H+ → N2 + 6 H2O.
