More specifically, I showed that diminishing marginal returns is equivalent to a marginal physical product( MPP) that declines with increases in the level of fertilizer that is used.
具体地说，我说明了边际报酬递减就是边际产量随着肥料用量的增加而递减。
5.
In particular, an increase in the amount of nitrogen applied has the effect of increasing the MPP of potash.
特别是氮肥用量的增加具有提高钾肥边际产量的作用。
6.
In this situation, maximum yield occurs when the MPP for both fertilizers are equal to zero.
在这种情况下，最高产量产生在两种肥料的边际产量都等于零的时候。
7.
The estimate of the MPP of potash is positive and statistically different from zero.
对钾肥边际产量的估计是正值，而且统计上显然不等于零。
8.
Table 2 also shows that a change in the level of nitrogen application affects the MPP of potash use for any given level of potash use.
表2又表示在钾的各个用量水平，氮肥用量的变化对钾肥边际产量的影响。
9.
To determine the optimal allocation of fertilizer in this situation, it is necessary to know the relative size of the MPP of potash in all regions.
在这种情况下，为了肥料分配最优化，需要知道所有地区钾肥边际产量的相对大小。
