Question

Quizplus · Accepted Answer

Humans contribute to nitrogen fixation primarily through the production of artificial fertilizers and the burning of fossil fuels. Artificial fertilizers add fixed nitrogen directly to the soil, enhancing plant growth. Burning fossil fuels releases nitrogen oxides into the atmosphere, which can eventually deposit as fixed nitrogen on the earth's surface.
