Human fertilizer use has doubled the amount of nitrogen and phosphorous entering rivers .
化肥的使用使进入河流的氮和磷增加了一倍。
But the effects of these loads of nitrogen and phosphorous extend beyond the field and past the growing season .
然而,土地中的氮和磷所产生的效力扩散到了农田之外,且持续到生长季节之后。
The situation is aggravated by government distribution of chemical fertilizer containing extra phosphorous to poor farmers who liberally apply it to their fields .
There is also the alleged use of white phosphorous shells : permitted as a smokescreen , but not over civilian areas .

Gordon sato found a way to provide these minerals by putting nitrogen , phosphorous and iron into small plastic bags at the base of each tree .
佐藤通过将氮、磷和铁放入每棵树根部的小塑料袋,找到了提供矿物质的办法。
Known life on earth is based on five main elements carbon , hydrogen , oxygen , nitrogen and phosphorous but it is possible that organisms could use arsenic instead of phosphorous .
地球上已知的生命包含5种主要元素碳、氢、氧、氮和磷有机体也可能用砷代替磷。
I think we will see a lot of upcoming debate on whether or not the amount of phosphorous present was enough for the bacteria to have " normal dna " .
我认为,更多的讨论将围绕磷的量是否足够产生“正常dna”。
The results showed changes to turbidity and dissolved oxygen , pollution levels of nitrogen and phosphorous , dense phytoplankton blooms , and high fecal coliform concentrations .
结果表明,浑浊度和溶解氧的变化,氮和磷的污染程度,密集的浮游生物,高浓度粪便大肠菌群。
Less well known but just as profound are the similar impacts of human activities on other critical natural systems , such as the nitrogen , phosphorous , sulfur , and water cycles .
