Damiano says that in extreme heat, and when that heat is dry, soil moisture evaporates quickly.

达米亚诺说，在极端高温下，当又干又热时，土壤水分蒸发得很快。

Mulch not only keeps things looking clean, but it also helps to keep soil moisture and soil temperatures even.

护根物不仅让植物看起来干净，而且还有助于保持土壤水分和土壤温度均匀。

And within each plot we will take soil moisture measurements.

在每个地块中，我们将进行土壤水分测量。

El Nino is likely to help increase soil moisture in the U.S. Plains – an area stretching through the middle of the country.

厄尔尼诺现象可能有助于增加美国平原的土壤湿度，该地区一直延伸到美国中部。

In its August analytical report, the European Drought Observatory said some 47 percent of Europe is under warning conditions due to a severe lack of soil moisture.

该观察站 8 月发布的分析报告中指出，由于严重缺乏土壤水分，欧洲有大约 47% 的地区处于警告状态。

So, the same extra heat pulls the soil moisture out of the ground and causes these deeper, longer, more pervasive droughts and many of them are underway right now.

所以，同样的，额外的热量让土壤中的水分蒸发了出来，造成了更严重的，更长时间的，和更普遍的干旱，并且这种情况正在持续发生。

Still, the findings suggest that, in the absence of soil moisture, pea plants can detect the sound of water in pipes and follow it to its source.

尽管如此，研究结果表明，在缺乏土壤湿度的情况下，豌豆植物可以检测管道中的水声并追踪其源头。
