The Movement of Nitrate Nitrogen Through Columns of Coarse-Textured Soil Materials1

  1. Thomas E. Bates and
  2. Samuel L. Tisdale2



A laboratory investigation was undertaken in which the movement of nitrate nitrogen through columns of coarse-textured soil materials was studied. Eight soil materials from the Coastal Plain region of North Carolina were used, and the movement of added nitrates as a function of the porosity of these soils and the quantity of water added to the columns was determined. A multiple regression equation was developed which permitted an estimate of the mean nitrate movement from a knowledge of the value of these two variables.
