- Contrary to data available in the literature, minimum tillage in our investigation did not give exceptionally good results. 与文献中出现的资料相反,在我们的研究中对田地作最小量的耕翻并没有产生特别良好的结果。
- Nitrate leaching, although slightly higher under no tillage, is generally not a major pathway of loss in summer crops. 实施免耕的初期,氮的生物固定明显,但随着时间的推延,这种作用逐渐消失,以至到了后期,与初期的情况正好相反。
- Denitrification, on the other hand, can be very serious with a combination of no tillage and imperfectly drained soils. 硝态氮的淋失虽然在免耕制下稍高一些,但在夏季作物上,一般不是氮损失的主要途径。
