One American investigation into the potential for storing CO2 on agricultural lands is taking place in California.

美國的一個關於在農業土地上儲存二氧化碳的可能性的研究正在加利福尼亞州進行。

Soil scientist Whendee Silver of the University of California, Berkeley,

來自伯克利市加州大學的土壤學家Whendee Silver，

is conducting a first-of-its-kind study on large cattle farm in the state.

正在對該州的大型養牛場進行首次這類研究。

She and her students are testing the effects on carbon storage of the compost that is created from waste

她和她的學生正在測試由廢物製造的堆肥中儲存的碳的作用，這些廢物既來自農業廢料，

both agricultural, including manure and cornstalks, and waste produced in gardens, such as leaves, branches, and lawn trimmings.

包括糞肥和玉米杆，也來自花園中產生的廢物，比如落葉、樹枝和修剪草坪產生的廢料。

In Australia, soil ecologist Christine Jones is testing another promising soil-enrichment strategy.

在澳大利亞，土壤生態學家Christine Jones正在測試另一種可能的土壤增肥策略。

Jones and 12 farmers are working to build up soil carbon by cultivating grasses that stay green all year round.

Jones和12位農民正在一起通過培育全年常綠的草來增加土壤中的碳質。

Like composting, the approach has already been proved experimentally;

和堆肥一樣，這種方法在試驗階段也已經被證明有效，

Jones now hopes to show that it can be applied on working farms and that the result in carbon capture can be accurately measured.

Jones現在希望證明這種方法能夠應用在運營中的農場裏，以及獲取的碳的結果是能夠精確計算的.。

It's hoped in the future that projects such as these

我們希望將來像這樣的項目，

will demonstrate the role that farmers and other land managers can play in reducing the harmful effects of greenhouse gases.

會證明農民和其他土地管理者在減少温室氣體的有害影響中能夠發揮的作用。

For example, in countries like the United States, where most farming operations use large applications of fertiliser,

比如，在像美國這樣的，大部分農業操作過程中都會使用大量肥料的國家，

changing such long-standing habits will require a change of system.

改變這種存在已久的習慣將需要一種系統的變化。

Rattan Lal argues that farmers should receive payment not just for the corn or beef they produce

Rattan Lal認為農民應該不僅從他們生產的玉米和牛肉中獲利，

but also for the carbon they can store in their soil.

還應該為他們在土地中能夠儲存的碳質獲得報酬。
