摘要

Hansen et al. conclude in their paper "regulation and technical improvements in the intensive fanning in Denmark have succeeded in decreasing the N surplus by 40% since the mid-1980s, while at the same time maintaining crop yields and increasing the animal production of especially pigs. Trend analyses prove that the youngest (0-15 years old) oxic ground-water shows more pronounced significant downward nitrate trends (44%) than the oldest (25-50 years old) oxic ground-water (9%).
