So it keeps these areas warmer, which causes increased microbial activity.

因此它让这些区域变暖，这导致微生物活动增加。

Particularly, the infusion of large amounts of nitrogen fertilizers caused disruption to this microbial activity and changed the population dynamics.

尤其是氮肥的大量使用导致了微生物活动的紊乱，改变了微生物种群的动态。

And of course as mentioned, more microbial activity means more food and nutrients for the shrubs, which leads to more shrub growth.

当然如前所述，更多的微生物活动意味着灌木丛有更多的食物和营养，从而导致更多的灌木生长。

This little bacteria [that] used to be a small, subdued microbial activity in the soil biological activity, has grown now into a monster.

这小小的细菌曾经那么微不足道，只是土壤生物活动中微小的一环，现在却成了一个大麻烦。

This little bacteria used to be a small, subdued microbial activity in the soil biological activity, has grown now into a monster.

这种小细菌曾经是土壤中生物活动受抑制的小型微生物，现在已经成长为怪物。

As I said, what used to be a small, insignificant microbial activity in the soil has grown into a monstrous proportion, sucking up all the fertilizer nitrogen we are applying.

如我所说，以前土壤中这微不足道的微生物活动已经长成了庞然大物，吸收了我们投入的所有氮肥。
