  • Nitrogen in the Environment: Leaching | MU Extension

    When soil becomes excessively wet through rainfall, the soil will reach a point where it cannot hold any more water. This happens because the air spaces between soil particles become filled with water. As these air spaces fill, gravity will cause water to move down through the soil profile. (It can also pound or run off the surface of the soil.) As water moves down through the soil, nitrogen ...
