- 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。
- Typically, magnesium levels in soils under no tillage do not change materially from those under conventional tillage. 免耕和传统耕作制相比,土壤中镁的含量没有实质的变化。
- Application of phosphorus fertilizer to no tillage cropping systems appears to be complicated by the fact that it cannot be incorporated. 免耕耕作制下磷肥的施用似乎很复杂,因为此时无法将磷肥和土壤掺混。
- Immobilization effects are notable in the early years of no tillage, but with time they tend to disappear and even reverse themselves. 在所有作物上液氨都必须和土壤掺混(在条施时必须把缝隙封好)。

- Summarizing phosphorus fertilization under minimum and no tillage, it can be said that surface broadcast applications generally work very well in terms of plant uptake and for maintaining adequate soil levels of available soil phosphorus. 综上所述,免耕制和少耕制下磷肥的施用,从植物吸收的角度和从维持足够有效水平的角度来考虑,地表撒施一般效果很好。
