Establishment of simple measurement method of nitrate nitrogen by using coupling reaction
1993 - 1994
Investigating Researcher (2)：
They say that a high concentration of nitric acid-type nitrogen is contained in fodder crops produced by using cattle excreta in an excess amount. When content of nitric acid-type nitrogen goes up to 0.2% in a dried material, there is a possibility of acute poisoning by nitric acid. To prevent this, we establish a cropping method in an optimum period and at an optimum position by utilizing a simple measuring method.
