| Abstract: | The advances in the researches on nitrogen leaching from vegetable soils, and effects of the leaching on underground water are reviewed in this paper. Meanwhile, lysimeter, soil solution distill utensil and 15N isotope trace technique for determining the leaching are also introduced. Some key factors influencing the leaching are discussed and some control measures are put forward. |
| Keywords: | vegetable field nitrogen leaching control measures |
