空气不能穿透土壤颗粒，这使得土壤中缺少氧气。
Air cannot penetrate between the soil particles, making the soil oxygen-poor.
我们给土壤充气，允许氧气通过我们的蚁丘而少量充满在土壤中。
We aerate the soil allowing oxygen to be present in small amounts through our anthills.
随后氧气就被其它表面活性剂附着而运输到土壤中的更深地方，来滋养那些需要这些养分的植物。
The oxygen then is carried by other surfactants that attach unto it deeper into the soil to nourish those plants requiring such sustenance.
他们也在研究如何从从月球的岩石和土壤中提取氧气和其他重要元素。
They are learning how to extract oxygen and other vital elements from lunar rocks and soil.
好的介质能够让氧气进入土壤，让二氧化碳和其他废气排出，因此重量上会非常轻。
A quality mix will allow oxygen to enter and carbon dioxide and other gasses to escape and therefore must be light in weight.
然而科学家们正致力于研究一种从月球土壤中的氧化铁里获得氧气的方法。因为未来月球基地意识到在地球上以这种方式炼钢更好。
But scientists working on a way to harvest oxygen from the iron oxide in lunar soil for future moon bases realized that they happened on a better way to make steel here on Earth.
太多的盖土会阻止氧气和水流入土壤，同时还会对根系有害。
Too much mulch can restrict oxygen and water flow to the soil and harm roots.
本发明应用于盐碱地土壤，能够改善泥土的结构及提供足够的水分、氧气及营养，提高作物的产量及质量。
The invention is applied to saline soil, can improve soil structure and provide sufficient water, oxygen and nutrient to improve the output and the quality of crops.
月球上的土壤有约50%是氧气，科学家们认为氢气来自于刮到月球表面的太阳风。
The lunar soil is nearly 50 percent oxygen, and the scientists think that hydrogen comes from the solar wind that pounds the moon's surface.
实验结果表明：改进的汉普仪法测土壤中氧气百分含量，操作简单，能够满足现场测定，可以通过干洁空气为标准气体进行误差校正。
Experimental results showed: Industry oxygen can measure soil oxygen content percent meet the site measurement, ready to measure air as gas calibration standards.
树木的减少扰乱了生态系统，因为固定表层土壤，保持旱季降雨，净化地下水和将二氧化碳转化为氧气都需要树木。
The loss of trees upsets the ecosystem as trees are necessary to build topsoil, maintain rainfall in dry climates, purify underground water and to convert carbon dioxide to oxygen.
