Nitrate Occurrence in Some Soils With and Without Natric Horizons Academic Article uri icon


  • The effect of animal activity and fertilizer practices on the nitrate content in soils with and without natric horizons was investigated in a field study in southern Illinois where excessive ground-water nitrate levels were reported. Most of these soils are poorly drained. A comparison is provided by the poorly and well-drained soils without natric horizons observed in cen? al Illinois. The results indicate that soils with natric horizons at shallow depths or dark-colored poorly drained soils had low levels of nitrate in the profile; all other soils showing increased nitrate levels in the entire profile or below the root zone were related to the amount of fertilizer used or the amount of nanimal activity. Animal operations resulted in larger amounts of nitrate in similar soil profiles than did fertilizer applications. Increased nitrate content of the ground water, sampled in Washington County, similarly was related to fetilizer practices and animal activity in all soils, except under soils with natric horizons at shallow depths.
