| Abstract | The intensification of agricultural production, livestock and aquaculture in regions of La Araucanía, Los Ríos and Los Lagos, has provoked negative impacts on agroecosystems which has been confirmed as significant accumulations of nitrate (NO3 -), nitrite (NO2 -) and agrochemicals in agricultural soils and waterways. The reduction of NO3 to nitrogen gas (N2) via denitrification route, carried out by heterotrophic soil bacteria under anaerobic conditions is a subject of great economic and environmental significance, considering the effect of this process in reducing NO3 leaching into groundwater. The use of remediation methods to remove NO3 and other contaminants in soils helps to remediate already polluted agroecosystems and other under risks. |
