| Research Abstract |
Summary of research results on The Research of Underground-water Contamination by Nitrate-nitrogen is as follows.
(1) Nitrate-nitrogen and other fertilizer elements, underground-water contaminations were measured, and they showed the same patterns.
(2) Positive correlation between the past use of nitrate-nitrogen as a fertilize and the nitrate-nitrogen in the underground-water was recognized.
(3) Correlation between rainfalls and nitrate-nitrogen was recognized.
(4) Researching by boring for the tendency of contamination speed and the expanding, no clear result was derived.
