The reason this process … WebThere are two ways in which nitrogen fixation can occur. 1. The first method is through lightning. Nitrogen is fixed into nitrates when energy produced by lightning causes nitrogen gas to react with surrounding oxygen in the air. The nitrates then dissolve into water (either through rain or surface water), enter the soil and are used by plants. 2.
