Test kit for analysis of nitrate nitrogen concentration in soils and its analysis method for detection using the same

摘要

The present invention relates to a kit to detect nitrate nitrogen (NO_3-N) concentration in soil, and a nitrate nitrogen concentration detecting method using the same. When nitrate nitrogen in the soil is measured in accordance with the detection method of the present invention; not only a same accuracy as that of a conventional method is able to be secured, but a reaction time of the nitrate nitrogen and a coloring reagent is also able to drastically be shortened. In addition, expensive analytical equipment is not required, and it is possible to provide nitrate nitrogen detection reagent harmless to the human body by supplementing disadvantages of using heavy metals.
