| Research Abstract |
Nitrogen concentration of stream waters and landuse in the agricultural area
The relations between NO3-n concentration and landuse were investigated in Hokkaido area
High concentration of NO3-N were measured in the ground water under the vegetable field in Kanto area
Nitrogen removal in paddy fields
Nitrogen removal were measured in paddy fields
The effect of NO3-N concentration and temperature on nitrogen removal were investigated, and the equation of nitrogen removal was introduced
