NWRI contribution ; no. 01-210 Digitized edition from print [produced by Environment and Climate Change Canada]. Includes bibliographic references. "This report investigated the nitrate levels in precipitation and in tile effluents including the effect of nitrate-nitrogen on corn development and yield in a pair of field plots. The plots were kept under grass with zero input of fertilizer or manure for more than five years. The levels of nitrate in tile effluents from both plots were compared with the nitrate input from precipitation where the influences of nitrogen fertilizer on the com developmentand yield were evaluated in terms of length and width of corn leaf, stern size and height of corn between the fertilized and the unfertilized plots"--Management Perpsective.
