In this paper,We mainly studied the seasonal change of NO_3-N content in soil profile ofdifferent experiment plots and the relationship between land use and crop growth in the middle partof Hessen,Germany.Moreover,the variations of NO_3-N in the soil were detected and their effectson the pollution of underground water were also discussed.Still more,Mulching effects of fallowland crops were evaluated.
